In the heart of the French region of 00:03
Burgundy, the small town of Clooney 00:05
holds a secret. Once a gigantic church 00:07
stood here, now barely onetenth of the 00:11
original remains. 00:13
In its day, it was the largest abbey in 00:16
the world. 00:18
[Music] 00:21
Its pillars rose more than 30 m. 00:23
Its nave spans 60 m longer than 00:27
Notradamand de Pari. 00:30
300 windows illuminated the building. 00:33
It was called Mayor Ecclesia, Latin for 00:38
the largest church. 00:41
>> It was an absolutely incredible 00:44
technical feat. They managed to build 00:46
something that was simply oversized for 00:48
the era. 00:50
Built by 11th century monks in less than 00:52
70 years, it would remain Western 00:55
Christianity's largest church for five 00:57
centuries, defying all architectural 01:00
standards and declared a second Rome. 01:03
>> It looked directly to the papacy in Rome 01:08
for direction. 01:11
But after the French Revolution, this 01:13
peerless abbey was abandoned, destroyed, 01:16
and sold stone by stone. 01:19
>> The site completely deviated from the 01:24
concept of an abbey. 01:26
>> For nearly a century, archaeologists and 01:28
historians have searched for traces of 01:30
the abbey in the walls of the city. 01:32
They've discovered that the builders of 01:35
this church had mastered extraordinary 01:37
techniques. 01:39
And so they must have wanted to build 01:41
very high from from the from the word 01:43
go. You don't build vast foundations if 01:46
you're going to have a small church with 01:50
nothing on top of them. 01:52
How did the monks meet the challenge of 01:55
building such a tall and stately abbey 01:57
almost a thousand years ago? Where did 01:59
they find the materials? How did they 02:01
transport them? 02:04
[Music] 02:09
Now the greatest experts on the Clooney 02:11
Abbey, meticulous computerenerated 02:13
reconstruction and 20 years of hard work 02:16
will reveal the lost secrets of the 02:19
Mayor Ecclesia. 02:22
[Music] 02:26
Clooney Abbey was located in a remote 02:33
valley in the heart of Burgundy in 02:36
southeastern France. 02:38
Within the walls of the lost religious 02:42
city once stood the largest abbey ever 02:44
built in the Middle Ages. 02:47
More than 90% destroyed after the French 02:50
Revolution. Only a few vestigages 02:53
remained which were swallowed up by the 02:55
city that developed over the centuries. 02:57
[Music] 03:01
How could one calculate the dimensions 03:03
of the original church? What did it look 03:05
like? Today, only the large southern 03:07
transep remains with its octagonal 03:10
tower, the last vestage that proves the 03:12
once colossal size of the building. 03:15
>> Because it's the only bit of Clooney 03:21
that's left, one forgets just how 03:23
gigantic it is. 03:26
And the transcept that survives is, you 03:29
know, twice the size of the average 03:32
church, isn't it? In in its own right, 03:34
and it's only one of two transcepts. 03:36
The dimensions of the tower were unheard 03:40
of for a building from the Middle Ages. 03:42
It was more than 60 m high and 03:45
overlooked the valley. 03:47
The interior vaults measured up to 30 m. 03:49
[Music] 03:57
This tower awakened the curiosity of 04:01
historians to find the plans of the 04:03
missing abbey. 04:05
Only one existed, preciously preserved. 04:07
It dates from 1700 and was made by an 04:10
anonymous person. The precision of the 04:13
drawing is the only trace of what this 04:16
extraordinary church was like. 04:18
>> This is the oldest plan of the abbey. 04:21
the earliest testimony to its existence 04:24
in Clooney. 04:26
It was a huge monastery. 04:31
To give you an idea, from the end of the 04:34
11th to the 12th century, it housed 04:36
approximately 300 monks. 04:39
At the height of its existence, Mosame 04:43
Michelle had only 80 monks. So, it was 04:44
truly colossal in size. 04:47
[Music] 04:49
The abbey was a veritable city that 04:52
stretched over 15 hectares, almost half 04:54
the size of today's Vatican with 04:56
buildings that were oversized for the 04:59
time. 05:01
Some are still visible in the city, such 05:04
as the Miller 05:06
and the inn. 05:08
Yet, the highlight of the map that 05:12
intrigued the researchers was the size 05:14
of the aashial church in the middle. 05:16
When you look at the scale of the large 05:21
aial church, you see that it was 05:23
colossal. 05:25
>> It was 187 m long. To put it into proper 05:29
perspective, it was 60 m longer than 05:33
Notradam de Par. 05:35
The church was bigger than Notraam de 05:38
Pari, St. Peter's Basilica in Rome, 05:40
Chartra Cathedral, and the Basilica of 05:42
Sandini. 05:45
In size, it beat any other church in the 05:47
Middle Ages. 05:50
Its unrivaled length held double aisles, 05:55
11 spans, two transcepts, a small and 05:58
large with a width of 75 m. A chancel 06:02
and an apps composed of multitudes of 06:05
radiating chapels named Apicidol. 06:08
To understand the size of this 06:13
monumental church, we must go back to 06:14
the time of its creation, which began 06:17
with a key asset. 06:19
[Music] 06:21
The location on the site itself is 06:24
linked to a donation made in 1910 by the 06:27
Duke of Akiten. 06:30
He gave a plot of land, an old villa to 06:32
a handful of monks. 06:35
But he had the distinction of placing 06:38
this community under the direct 06:40
responsibility of Rome. 06:42
>> It was directly 06:45
subservient or looked directly to the 06:47
papacy in Rome for direction. So it 06:51
considered itself in a sense I suppose 06:54
to be a second row. 06:56
Its direct attachment to Rome gave it a 07:00
privileged status. But the abbey became 07:03
even more important a few years after 07:05
its creation thanks to a specific event. 07:07
They brought relics to Clooney first of 07:10
St. Peter and St. Paul and then relics 07:12
in numbers such as Clooney competed with 07:14
St. Peter's Basilica in Rome and gave 07:16
rise to a very large veneration of 07:18
relics. 07:20
One could come to venerate the relics of 07:24
St. Peter or at least pray around the 07:26
abbey. It was a bit like making a 07:28
pilgrimage to Rome. I'm slightly 07:30
exaggerating but not much. There was a 07:31
very strong connection to Rome. 07:34
>> The first church called Clooney 1 07:39
quickly became too small. 07:41
The monks built what was named Clooney 2 07:44
and little larger. But 20 years later, 07:47
this church was deemed to be too narrow. 07:49
They then built Clooney 3, the Mayo 07:56
Elesia or biggest church. 07:58
The idea was to build a church that 08:05
could perhaps accommodate up to 1,000 08:06
monks or at least a very large number of 08:08
them that were either on site or passing 08:11
through. It was absolutely vital to have 08:14
something more imposing that was really 08:16
in the image of this second Rome. 08:18
They wanted the best, the greatest, the 08:22
most beautiful, and the brightest to 08:25
manifest their faith in God, but also to 08:27
show his strength and his power. And 08:31
that the greatest, be they emperors or 08:34
even the pope, should do that with 08:36
Clooney. 08:38
At one point, Rome could not do without 08:42
the Clooney Abbey. The abbott of Clooney 08:44
was an essential person in medieval 08:46
Europe of the 11th and 12th centuries. 08:48
Abbert 08:50
Hugh of Seamur launched the construction 08:55
of Clooney 3, the Mayo Ecclesia in 1080. 08:58
His goal was to build the largest church 09:02
ever. But the monks were immediately 09:04
faced with a problem, the location. 09:06
How could a huge church be built on a 09:12
cramped site at the junction of two 09:14
rivers and on the steep slope of a 09:16
valley? 09:18
The site where Clooney was built wasn't 09:22
very good for construction. In fact, it 09:24
was somewhat of a flooded basin. To the 09:27
east, there was the Grown River that 09:29
flooded often, creating silt. The soil 09:31
was very unstable up to the level we're 09:33
at now, where natural terrain began. 09:35
>> The heart of the church had to face east 09:41
towards Jerusalem. So the monks had to 09:44
level the hillside to create a base by 09:46
removing thousands of cubic meters of 09:49
earth. 09:51
These were considerable earth works. 09:56
They had a bit of difficulty since they 10:00
were perpendicular to the slope of the 10:02
hill and consequently were forced to 10:04
carry out a number of works to try to 10:07
get it leveled. 10:09
There were layers of land that were not 10:14
very homogeneous 10:16
and the eastern parts were still quite 10:19
wet. 10:21
That's why they built extremely strong 10:23
foundations. 10:25
>> You need solid foundations to build 10:31
high. The Clooney monks understood that 10:33
very well. 10:35
The chapel of Jean de Bourbon at the 10:38
extreme southeast of the aial church was 10:41
redesigned in the 16th century. 10:43
Excavations are underway to find the 10:46
ancient foundations of the abbey led by 10:48
Fabis Orion, an archaeologist at the 10:51
center of medieval studies. 10:53
What's quite extraordinary is that we're 10:57
in the foundations. This is extremely 10:59
well-designed and well-built masonry. 11:01
And yet it wasn't visible but in the 11:04
ground buried in the foundation 11:06
trenches. 11:08
It's a very high quality construction. 11:09
The limestone blocks are perfectly cut. 11:16
Their thickness varies from 6 to 18 cm 11:18
and they're connected by mortar. 11:21
The foundations were deep because the 11:26
builders looked for hard ground to use 11:28
as a base. 11:30
Here 11:32
they were really trying to make deep 11:34
solid foundations in order to bear the 11:36
weight of the whole structure. 11:39
The depth of the foundations followed 11:44
the slope of the valley to reach the 11:46
hard rock up to 4 m deep in certain 11:47
places. 11:50
They were also extremely thick. On the 11:52
western part of the transcept, the 11:54
foundation wall was 5 m wide. 11:56
From the start, um, the foundations were 12:02
colossal. They're big and they're very 12:05
deep on a site which is not easy to 12:07
build on. And so they must have wanted 12:11
to build very high from from the from 12:14
the word go. You don't build vast 12:17
foundations if you're going to have a 12:19
small church with nothing on top of 12:22
them. 12:24
>> To stabilize the foundations, the monks 12:26
went even further. 12:28
Each wall and each pillar base were 12:31
connected by 3.5 m thick masonry. 12:33
All the structures were firmly anchored 12:38
to each other. 12:39
These walls were brought together 12:46
including those under the arches. 12:48
So from one wall to another or from one 12:50
pillar to another were foundations that 12:53
followed each other. 12:55
It's called a sill plate, which is a 12:57
kind of grid. 12:59
>> This grid stabilizing the soil was a way 13:04
of connecting the support points that 13:06
these pillars represented. 13:08
>> Once it was done, you could build 13:11
whatever walls you wanted. 13:12
>> If the ground moved, the entire building 13:13
moved, but it wouldn't fracture. There 13:16
lies the genius behind the construction. 13:19
Engineers from National 13:22
did a simulation and realized that these 13:24
foundations had enormous purpose. 13:27
Had they not been there, the monument 13:30
wouldn't have stood. 13:32
At the beginning of the 20th century, an 13:36
archaeologist also took a keen interest 13:38
in the foundations of the lost church. 13:40
American Kenneth John Conand would 13:43
change the fate of the abbey. 13:46
when he arrived everything was under 13:52
grass. There was no sign of of 13:53
foundations or anything like that. The 13:55
only thing that survived was the the 13:58
great transcept and the little eastern 13:59
transcept and the chapel bon Jean de 14:02
Borbong and so on that little group of 14:04
buildings but apart from that there 14:06
wasn't anything really visible. 14:08
>> The site had completely taken over the 14:11
area. It was a little like the Camair 14:14
temples where vegetation invades the 14:16
temples. In Clooney, the city took over 14:19
the area completely surrounding the 14:21
abbey. 14:23
[Music] 14:25
The site had completely deviated from 14:31
the concept of an abbey. 14:33
So, Conant worked for nearly 40 years to 14:35
find not only the plan, but to 14:38
reconstruct the lost volumes of this 14:40
exceptional building. 14:42
Using rare artist drawings from the 18th 14:49
century showing the abbey and its 14:52
church, Kenneth John Conand had only one 14:54
obsession to find the exact dimensions 14:57
of the building. 14:59
To do so, he analyzed the foundations, 15:02
their thickness, and their composition. 15:05
Finally drawing hundreds of plans which 15:07
revealed the abbey in volume for the 15:09
first time. 15:11
[Music] 15:14
Conant was the one who rediscovered the 15:18
Clooney Abbey. He was the first to have 15:20
proposed reconstitutions of the aial 15:23
church in all its original and later 15:25
splendor. 15:27
[Music] 15:29
Through his research, Conan discovered 15:30
the entire size of the building. 15:33
The nave of the church was composed of a 15:39
double span punctuated by 18 monumental 15:41
pillars. 15:44
[Music] 15:50
It also featured a transcept itself 15:52
followed by a smaller one. 15:55
Finally, there was the chancel with 10 15:59
pillars that formed an ambulatory. 16:02
Three floors of windows bathed the 16:09
church in light 16:11
and the vaults were 30 m high. 16:15
[Music] 16:19
In the 11th century, no other church 16:21
matched it in height and dimensions. It 16:23
was the largest, highest, and brightest. 16:26
But how did the monks manage to create 16:34
such a masterpiece using the techniques 16:36
of the Middle Ages? 16:38
The 10th century was the golden age of 16:42
Romanesque arts. Churches were modest in 16:44
size, not exceeding 20 m tall with thick 16:47
walls and small windows, far from what 16:50
the monks wished to achieve. 16:53
>> The churches of the 11th century were 16:56
darker, usually because their windows 16:58
were cut into the walls of the tribunes. 17:00
The naves were rarely lit directly. 17:03
The churches were rather squat. 17:07
The monks of Clooney decided to raise 17:10
the walls 17:13
to build very high vaults and to add 17:14
many windows. 17:17
[Music] 17:21
At the time, the vaults had a 17:23
semic-ircular arched shape typical of 17:25
Romanesque art. The semicircle supported 17:27
the weight. The diameter was therefore 17:30
equal to the width of the vault. The 17:33
height of the vault was the radius. 17:36
To increase the height, the nave had to 17:45
be widened. But the bigger it got, the 17:47
more the forces at hand weakened the 17:49
structure. 17:51
To build higher, they had to find a 17:53
solution other than the semic-ircular 17:55
arch. 17:57
They were driven by the necessity of 18:00
solving this technological problem to 18:02
guarantee the stability of the building. 18:05
At one point, the genius idea of using 18:08
Gothic arches must have come into the 18:10
mind of the site manager as a way to 18:12
solve this issue. 18:14
The Gothic arch is two half circles with 18:19
centers located at the extremities of 18:22
the vault. 18:24
They intersect and this forms a Gothic 18:27
arch. 18:29
The width is no longer related to the 18:32
diameter as it is for the semic-ircular 18:34
arch. It can reach 2/3 of the arch. 18:36
It's therefore possible to build higher 18:42
than with a semic-ircular arch. 18:44
>> The Gothic arch existed before Clooney. 18:48
It wasn't conceived specifically for 18:52
Cooney, but it was used because of its 18:53
interesting characteristics. 18:56
In the Romanesque style, all arches were 18:58
systematically semic-ircular. 19:01
For Clooney, however, they could not be 19:04
used for reasons of stability. 19:06
At that time, it was quite innovative 19:09
because it would allow the weight to be 19:11
better distributed over fully volted 19:12
parts. 19:15
With semic-ircular arches, the weight is 19:18
evenly distributed horizontally and 19:21
vertically. This requires thick walls to 19:23
prevent them from spreading under 19:26
pressure. 19:28
By breaking the arch into two half 19:30
circles, the horizontal component of the 19:32
weight is reduced and carried over to 19:34
the vertical component. 19:36
As a result, the walls can be thinner 19:39
and higher without the risk of 19:41
spreading. 19:43
From the moment these walls could be 19:47
higher in elevation, they could also be 19:48
cut more easily to create bay windows. 19:51
It was these openings that allow light 19:55
into all the vessels that made up the 19:57
nave and the aisles of Clooney 3. 19:59
[Music] 20:03
It's clear that behind what appears to 20:08
us to be essentially new forms, there 20:09
was above all technological research 20:12
at a level we would deem quite advanced 20:15
today. 20:17
But Gothic arches were not enough to 20:20
flood the nave with light while 20:21
maintaining the stability of the 20:23
building. It is this church plan that 20:25
allowed the architects to grasp the 20:27
level of mastery with which the Clooney 20:29
monks understood the balance of forces. 20:31
This is a cross-section of the large 20:36
nave of Clooney 3. 20:38
It was composed of a central aisle and a 20:41
double aisle. 20:43
The forces were redistributed by 20:47
staggering the aisles. 20:49
This shared distribution of lateral 20:53
force was achieved through the stability 20:55
of the outer walls with powerful 20:57
buttresses. 20:59
So it was a massive structure but a 21:03
particularly wellbalanced one. 21:06
There was a genuine effort made to 21:12
understand these forces. 21:14
These people displayed an exceptional 21:16
level of conceptualization. 21:18
There was a clear architectural and 21:20
engineering approach 21:22
typical of Romanes. The central naves 21:29
were buttressed with aisles. Here the 21:32
size of the building is such that the 21:35
monks added a third aisle maintained by 21:36
powerful outer buttresses. 21:39
The monks pushed Romanes art to its 21:42
limits. 21:44
The three floors of successive Gothic 21:47
arch vaults rose to 29.5 m, 17 m, and 10 21:49
m, allowing for a perfect balancing of 21:54
forces. 21:57
It was then possible to cut rows of 21:59
windows on each floor. 22:01
These windows represented a 45% void 22:04
compared to the walls. 22:07
[Music] 22:09
There were several rows of overlaid 22:12
windows which obviously allowed them to 22:14
create an unrivaled luminosity inside. 22:16
This is to evoke another spirituality 22:20
that of the divine that floods the place 22:22
of contemplation with his light. 22:24
[Music] 22:27
At that time, people didn't dare open 22:30
walls under vaults like this, especially 22:32
in a building as important as the Mayor 22:34
Elesia. So, this was very important and 22:36
very bold, and it foreshadowed what 22:39
Gothic architecture would later become. 22:42
>> In Gothic art, the structure carries the 22:48
building, not the walls. In Kuni, the 22:50
monks pushed the thought process of 22:54
force distribution to an extreme in 22:56
order to exceed the heights allowed in 22:59
Romanesque art right down to details 23:01
essential to balance. 23:04
This is notably the case with the 23:06
position of the pillars. 23:08
This narrowing, very subtle at each 23:11
level, allowed the springing point of 23:13
the vaults to be brought into the design 23:15
of the building and thus offer more 23:17
stability. 23:20
And so the oblique lateral strain was 23:24
better contained in the design of the 23:26
building. 23:28
The building was a balance between force 23:32
applied vertically and horizontally. 23:34
Butresses, arches, and the position of 23:37
pillars. Everything was present to allow 23:39
the monks to build a gigantic church. 23:41
[Music] 23:45
However, because the building was also 23:46
subject to torsional movement, the monks 23:48
paid attention to the slabs that 23:51
supported the top floor. 23:52
>> There was a whole system of staples that 23:55
actually locked the inner bands, the 23:58
last band at the top of the transcept. 24:00
So, all the parts were actually sealed 24:02
by these metal staples. 24:05
These were large staples 50 cm in length 24:12
by 2 cm in width and across. 24:15
The building was so large that they had 24:21
to take every precaution and resort to 24:23
any technique imaginable to achieve 24:25
stability and avoid deformation. 24:27
[Music] 24:31
But that wasn't enough. The monks were 24:38
still concerned about the pressure put 24:40
on the walls by the vault. So they 24:42
placed large iron bars along the entire 24:44
length of the nave. 24:47
Across the transcept there were these 24:52
bars of metal which held the thing taut. 24:54
These huge tier horn affair had to hold 24:59
the walls from from falling outwards. 25:03
You know 25:07
>> if they did it it was because there was 25:08
a need. So it's clear that the building 25:10
called for this kind of buttress. The 25:13
project was rather bold anyway. 25:16
Everyone in the middle ages knew Clooney 25:22
and the builders of the great cathedrals 25:24
knew it too. 25:26
They knew what the advantages or 25:29
disadvantages of various strategies 25:30
were. 25:32
That's why the Gothic arch implemented 25:34
in Clooney was reproduced in the great 25:36
cathedrals. The use of iron with staples 25:38
was used in Gothic architecture and so 25:41
on. 25:43
The abbey was splendid, grandiose, and 25:46
impressive. 25:49
The first stone was laid on October 25:51
25th, 1088. The monks began with the 25:53
southern arm of the great transep, the 25:56
only part that remains today. The site 25:58
then moved south to north and then to 26:01
the west. 26:04
[Music] 26:07
On the walls of the church, you could 26:13
see a multitude of holes left by the 26:15
workers scaffolding. These are called 26:17
putlog holes. 26:20
>> Putlog holes are small orififices that 26:24
were made into the wall at the time of 26:26
construction. That's how they could 26:30
stack the beams, trays, scaffolding, and 26:31
so on. 26:34
Their location provides information on 26:36
the evolution of the construction site, 26:39
notably the part that survived the 26:41
destruction, the large southern 26:43
transcept of the abbey. 26:45
We can see that the putlog holes which 26:51
are aligned horizontally on the first 26:54
two spans are not on the third. 26:55
There is a difference of 30 to 40 cm. 26:59
This is a sign that construction 27:03
stopped. What happened? 27:05
If we look at the third span in more 27:09
detail, the three highest windows are 27:11
not aligned with those just below. 27:14
Moreover, the band that marks the floor 27:19
suddenly stops and does not continue on 27:21
the third span. 27:24
All of these clues help us understand 27:26
what happened on the site at that time. 27:28
[Music] 27:31
There was a change of purpose. At first, 27:34
they set out to build a vaulted church 27:37
with 20 m under the vaults in order for 27:39
it to be lit directly. 27:42
But at this stage of construction, in 27:45
the middle of the transcept, they 27:46
decided to build 10 m higher. Plans were 27:48
changed. You can clearly see it in the 27:52
transcept. 27:54
[Music] 27:58
The first dome was 20 m high, the second 27:59
30 m, and the third was supposed to have 28:02
been 20 m high. 28:05
But the monks decided to go higher. By 28:07
placing this third dome 30 m high, they 28:10
were forced to shift the windows to the 28:13
north to leave room for the support 28:15
pillar. 28:17
[Music] 28:18
In their dream of gigantism, raw 28:26
material was essential. And in that 28:28
respect, the location of the abbey was 28:30
perfect. 28:32
>> For materials, it was perfect. 28:37
Everything needed was on site, both in 28:40
abundance and quality. That's 28:41
exceptional. There were limestone 28:44
quaries. 28:46
If you cook limestone, you get lime, 28:48
which is the binder needed to build. 28:49
They had sand from the grown river and 28:53
large quantities of clay to make the 28:55
floors, tiles, etc. 28:57
>> Not to mention, the valley was 29:00
completely covered with forests. 29:02
Near the construction site, less than 3 29:10
km away, were a multitude of quaries 29:12
with an abundance of stones. 29:15
[Music] 29:19
The farthest one was 18 km away. It's 29:24
the last still visible today. 29:27
The monks extracted white limestone 29:31
called piselite limestone. 29:34
We're here at the library. This is one 29:38
of the rare sources of soft stones in 29:40
the region. We know that stone was 29:42
extracted for sculpture. 29:44
The other quaries were composed of hard 29:49
stones used for construction. 29:51
There were three types of limestone with 29:54
different physical characteristics, 29:56
micrite, oyte and krenoidal. 29:58
There was also aros, a kind of 30:04
sandstone. 30:06
>> The programs were deliberately very bold 30:11
in terms of budget and technique. So 30:13
they looked for the best stone possible, 30:15
large sheets of bedrock that could make 30:17
big walls. 30:19
>> The most beautiful stones were cut 30:23
directly on site and placed so that they 30:24
were visible on the exterior. 30:27
>> The walls were made with two facades 30:31
that were relatively similar with rubble 30:33
stone cut more or less finely depending 30:35
on the area. 30:37
And in the middle was a mixture of 30:40
coarse mortar with all types of stone 30:42
waste to create a stable uniform block. 30:44
The wider it was, the higher it could 30:48
go. 30:50
>> It was an absolutely incredible 30:55
technical feat. They managed to build 30:58
something that was simply oversized for 31:00
the era with fairly simple means as the 31:02
walls were made with basic rubble. 31:05
That's how buildings had been 31:07
constructed since antiquity. 31:08
>> From these quaries, the monks extracted 31:17
a single stone 6 m long, 3 m high, and 31:19
45 cm thick. The tempanum. 31:23
It was placed at the entrance of the 31:28
large gate to impress visitors. 31:30
It was an extraordinary block in terms 31:34
of size considering the supply of the 31:36
local quaries. 31:38
>> Then it had to be moved which was also a 31:42
technical feat. 31:44
>> The idea was to use intelligence rather 31:47
than strength. 31:49
To carry the stone, the monks installed 31:52
a ramp that compensated for the slope of 31:54
the valley over 10 m in elevation. 31:56
The tempanum was then rolled on logs to 32:00
the large gate. 32:02
It was then lifted up using a hoisting 32:05
device called a jack, which reduced the 32:07
weight of the stone by a factor of 100 32:09
using the principle of traction levers. 32:12
The 28 ton stone was then placed on its 32:15
base. 32:18
>> This huge temp was lifted vertically on 32:24
these jams and was then sculpted. 32:26
They didn't want to take the risk of 32:31
creating that sculpture of Christ in his 32:33
glory before setting it up and digging 32:35
into the mass of the tempenum. Because 32:38
of the 45 cm thickness, they dug up to 32:40
40 cm to give depth to the sculpture. 32:43
[Music] 32:49
>> Christ was surrounded by four angels 32:50
whose remains found on the site show a 32:53
quality of sculpture that was unmatched 32:55
at the time. 32:57
In certain areas of the tempanum, only 5 32:59
cm of stone thickness remained. 33:02
>> From that moment on, an immense gate was 33:06
built that measured 14 m wide at the 33:09
base and 20 m high. 33:11
An architeure was placed at the top to 33:17
complete the composition. 33:19
ed as a genuine triumphal arch. 33:24
>> This was really in line with the idea 33:29
that Clooney would be restoring the 33:31
ancient world and Rome. 33:32
[Music] 33:36
>> The quality of the sculpture was just 33:42
breathtaking. When you came in through 33:44
the west door under that lintil that you 33:47
know and all the sculpture of the west 33:49
door and you looked down the whole 33:51
length of the church, what you saw was 33:53
the enormous Christ in the apps painted. 33:57
[Music] 34:03
There were more than,200 capitals 34:13
inside. which entails a gigantic number 34:15
of highquality decorations. 34:17
These were large capitals, 80 cm wide by 34:23
80 cm high. It was a colossal building, 34:26
the scale of which was quite remarkable. 34:29
>> Only eight capitals were found almost 34:35
intact. They adorned the pillars of the 34:37
ambulatory in the chancel. 34:40
Here 34:43
again the sculpture was carved with a 34:46
lot of depth so as to play with shadow 34:48
and light. 34:50
The majority of the capitals had 34:55
Corinthian themes. They were modeled on 34:57
Corinthian capitals. The reference to 34:59
antiquity was tremendous. 35:02
In antiquity you had temples with 35:04
columns and Corinthian capitals. 35:06
In the Clooney 3, they replicated the 35:10
colonade and borrowed Roman marble 35:13
columns that they trimmed and installed 35:15
around the chancel. 35:18
So, Clooney 3 was representative of 35:21
ancient Rome in all its splendor. 35:23
Above all, the monks wanted monumental 35:34
architecture. 35:36
With that 2 m diameter, the vestigages 35:38
of the pillars that punctuated the nave 35:41
bore witness to this desire. 35:43
The choice of the stones that composed 35:46
them wasn't the result of chance. 35:48
They didn't put just any stone in any 35:51
place. The base of the first pillars was 35:53
made of micrite limestone. With 35:56
moisture, the open transcept and the 35:58
destruction these stones degraded. Next 36:01
was a mixture of aros and limestone. Why 36:04
did they use micrite limestone which is 36:07
not particularly known for being of good 36:10
quality? Well, that stone is interesting 36:12
because it's very resistant to 36:15
compression. What was above it was 36:16
extremely heavy. the pillars, the 36:19
vaults, the dome all weighed on the 36:22
pillars. So they chose this stone to 36:24
support the vertical load. 36:28
>> Likewise, when the composition of the 36:34
walls of the still existent transcept is 36:36
analyzed, each stone has its function. 36:39
At the base, micrite limestone to 36:42
support the weight. In the middle, 36:44
strong and rigid sandstone. and at the 36:46
top soft limestone for the sculpted 36:49
capitals. 36:51
[Music] 36:54
At this point, 30 years had passed since 36:58
the first construction of the great 37:00
church Lamayo Ecclesia. The Clooney 37:02
Order was at the height of its power. 37:05
The Abbotts were in permanent contact 37:08
with the emperors, sovereigns, leading 37:10
figures of the world, and the papacy. 37:13
The Abbey couldn't be overlooked. 37:15
Gradually, it created what we called an 37:17
empire. They called it a religious 37:19
order, but it truly was an empire. 37:21
Today, for a company or a firm, it would 37:23
be called an empire. It was an abbey 37:25
that had subsidiaries, so to speak, and 37:28
throughout Europe, from England to 37:30
Italy, from Spain to Poland. It had an 37:33
enormous influence, spiritual of course, 37:36
but also temporal. 37:38
[Music] 37:41
More than 800 monasteries were created 37:43
and directly attached to the abbey. The 37:45
order was based on the rule of St. 37:48
Benedict, a return to spiritual life and 37:50
prayer. It resonated with world leaders. 37:52
The Abbotts also put into place an 37:58
entire strategy around the worship of 38:00
the dead, the feast of the dead, and the 38:02
need to pray for the dead. They 38:06
multiplied the altars, held more and 38:09
more masses for the souls of the 38:12
deceased and in each mass obviously the 38:14
coffers of the abbey increased. 38:18
Clooney had vast wealth at this time and 38:22
certain great sponsors 38:26
and it's clearly was the kings of of 38:28
Leyon and Castile. uh their their great 38:31
gold treasury which they the tribute 38:34
which which came to Clooney annually 38:37
from the northwest of Spain uh meant 38:40
that the coffers of Clooney were 38:43
bursting 38:45
and uh this incredibly ambitious 38:46
uh church project was was undertaken. 38:51
Clooney had colossal means. It was a 38:55
building that was erected very quickly. 38:57
>> Perhaps too quickly because in 11:25 an 39:01
event changed the structure of the 39:04
building. 39:06
>> In 11:25, the vault of the nave 39:08
allegedly collapsed. 39:11
>> One of the vaults most likely collapsed. 39:13
We don't know where. 39:15
>> It could be the great nave. It could be 39:16
an aisle. Could just be a little aisle 39:19
or a chapel or something. You know, it's 39:22
not it's not at all clear. Obviously, 39:24
the monks were devastated. Their dream 39:26
of greatness and prestige was ruined. 39:29
>> The monks had to review their plans and 39:33
determine what happened. How could a 39:35
building that had been so well thought 39:37
out be fragile? What was the mistake? 39:38
>> They didn't anticipate the fact that the 39:43
nave was very long. 39:45
The entire length of the nave had been 39:48
built using the same vault and the same 39:50
walls. But given that length, there was 39:52
a certain flexibility to it. 39:56
For example, if you take a pencil that's 40:00
5 cm long and you try to break it, 40:02
that's hard to do. But with a 30 cm 40:05
pencil, all it takes is a little snap 40:08
and you break it. So, what did they do 40:10
in the Middle Ages? They constantly 40:12
monitored the vaults. 40:14
The monks placed steep and narrow 40:17
staircases in the thick walls of the 40:19
abbey approximately 40 m in height. 40:21
From there, the monks could control the 40:26
structure. They might have noticed that 40:28
the vaults were fragile despite all of 40:30
their precautions. 40:32
What we do know is that they reinforce 40:36
the vault with walls called buttress 40:38
walls 40:41
in order to transfer some of the weight 40:43
and stabilize the vault of the central 40:46
aisle. 40:48
And to avoid having massive walls that 40:53
would change the perspective a little, 40:55
an arch was hollowed out in them. 40:57
The arches thus counterbalanced the 41:03
forces applied by the vaults onto the 41:05
walls. These arches would later emerge 41:07
in Gothic churches as flying buttresses. 41:10
>> Clooney 3 was really the transitional 41:18
building between typical classic 41:20
Romanesque art and Gothic art that would 41:23
flourish a few decades later. 41:26
It's traditionally believed that Gothic 41:30
art was developed in the Parisian region 41:32
and indeed most of the great monuments 41:35
of this period are concentrated there. 41:38
But the genius of the techniques that 41:42
allowed Gothic art to blossom really 41:44
took place in Clooney around 11:30. 41:46
In 1095, Pope Innocent II came to 41:52
consecrate the church. It wasn't 41:55
entirely finished. The last stone wasn't 41:57
laid until 11:30, 42:00
but as soon as it was completed, the 42:03
monks decided to build a 38 m long narex 42:04
that would end with two large towers 42:08
called barabans, culminating at 17 1/2 42:10
m. 42:14
There was a problem. The hill had to be 42:17
dug once again to integrate the 42:19
extension. 42:21
>> They wanted the narthx to extend into 42:25
the hill. topography. 42:27
>> The topography of the site and the 42:29
choice of location made by the monks at 42:31
the end of construction led to the fact 42:34
that one entered the church by going 42:36
down the steps, thus bowing to the saint 42:38
of saints represented by the magnificent 42:41
chancel of Clooney 3. 42:44
It was in Clooney that the legendary 42:48
Narthx was created, an anti-urch located 42:50
right in the front of the nave called 42:53
Galile because it refers to a very 42:55
specific liturgy pertaining to Easter 42:57
and the observance of Easter. 43:00
[Music] 43:03
>> Easter celebrates the resurrection of 43:07
Jesus. In all its grander, the front of 43:09
the Nate symbolized the passage to 43:12
eternal life. 43:15
[Music] 43:18
The aial church was finally finished. It 43:26
had risen from the earth in less than 70 43:29
years. 43:31
It imposed its power by its gigantism 43:36
dominating the center of the abbey. 43:39
This religious city was surrounded by 43:44
walls. 43:46
Its ramparts rose to more than 8 m and 43:53
were made of defensive towers and gates. 43:56
[Music] 44:01
The walls of the abbey weren't there 44:09
simply for the prestige. They were also 44:10
meant to protect in case of an attack 44:13
and there were several. And then you had 44:16
the city around the abbey along with the 44:18
walls of the city. So the abbey was a 44:21
small town within the town of Clooney. 44:24
When the abbey expanded, the 44:30
fortifications were enlarged as well. 44:31
And gradually by expanding, 44:33
it brought more and more people to these 44:36
sites. 44:38
Pilgrims had to be accommodated. So, a 44:40
hotel was built. 44:42
Visiting guests needed accommodating, 44:44
too. 44:46
We tend to forget that an abbey isn't 44:48
just a church, a closter, and a few 44:50
buildings. It's an entire economic and 44:52
cultural complex. 44:55
Very quickly the question of water 45:02
arose. How could it be provided to the 45:03
community? The monks resorted to two 45:06
rivers located on either side of the 45:09
abbey. The Medas and the Grun. 45:11
But this required making adjustments. 45:16
The medasau is a small stream that 45:21
originated west of Clooney and was 45:23
channeled under the city of Clooney. It 45:26
was used for the hydraulics of the 45:28
monastery and part of the city. 45:29
The water from the source of this stream 45:32
was transported into the monastery as 45:34
drinking water. 45:36
It was brought to the fountain of the 45:39
cloister and from there water was 45:40
distributed to the kitchen, to other 45:43
fountains and perhaps to the baths. 45:45
The monks used gravity. The slope went 45:50
from west to east and the midass flowed 45:53
naturally into the gon. The fountain of 45:56
the closter that received the water was 45:59
the highest in the abbey. 46:01
Once filled, it supplied the various 46:03
locations. 46:05
Using the drop in elevation, the monks 46:08
increased the pressure and made the 46:10
water gush. 46:12
The midas also served as sewer water. A 46:16
parallel network was to be created 46:20
evacuating sewage. 46:22
There were sewer systems that were 46:27
several hundred meters long. 46:28
Running water was injected into them to 46:31
carry away the waste. 46:33
There were flushing systems upstream of 46:35
the monastic latrines 46:37
which were large longitudinal buildings. 46:39
In these upstream systems, the valves 46:43
were opened and the fecal matter was 46:45
sent further downstream. 46:47
Very quickly, the abbey expanded towards 46:53
the GR and the monks diverted the course 46:56
of the river. They set up water 46:58
retention ponds upstream and downstream 47:00
of the river by building 5 m high and 47:03
370 m long dams capable of holding 200 47:06
hectares of water. In doing so, they 47:10
created a diverted canal that ran along 47:13
the valley and irrigated the entire 47:16
abbey. It was one of the most complex 47:18
hydraulic systems ever built in the 47:20
Middle Ages. 47:22
>> Clooney took a natural water system and 47:25
changed it into a completely artificial 47:27
network. 47:29
There was no natural water passing 47:31
through the city or the abbey at all. 47:32
[Music] 47:35
The monks set up 187 mills along the Gun 47:37
and inside the abbey which brought them 47:41
a colossal income. It was one of the 47:43
greatest senori of the Middle Ages. 47:45
In the middle ages, mastering water was 47:51
of course a sign of power and 47:53
technological knowhow. 47:55
The monks of Clooney were no exception. 47:58
Beyond the domestic dimension, there's a 48:01
spiritual dimension to water that helped 48:04
demonstrate the richness of the abbey. 48:06
The Clooney Abbey prospered for five 48:13
centuries thanks to a succession of 48:15
powerful amb. 48:17
The abbey started to decline in the 15th 48:25
century. In the 16th century, it was no 48:28
longer attached to Rome and lost a large 48:31
part of its income. In 1789, the French 48:33
Revolution brought about the end of the 48:36
abbey with its sale in 1798. 48:38
>> The Bashel church was sold in lots to 48:44
material traders and developers 48:47
who stone after stone patiently 48:51
dismantled the entire building. 48:53
In this huge church that was a 48:58
masterpiece of architecture, they only 49:00
saw a pile of stones that would allow 49:02
them to get richer. 49:04
>> The town encroached on a large part of 49:10
the abbey, namely the land located close 49:12
to the village. 49:15
As a result, there is currently an 49:17
interweaving between the current town 49:20
and the historic buildings of the abbey. 49:22
The site completely deviated from the 49:29
concept of an abbey. 49:31
>> Strolling through the city, one can see 49:38
a multitude of medieval houses, some of 49:40
which have pieces of the great abbey in 49:42
their walls. 49:44
In the masonry of the houses and in 49:50
private owned gardens, we often see 49:52
elements of a sculpture, a piece of 49:54
capital, a fragment of a portal or a 49:56
statueette that came from this great 49:59
church. 50:01
Over the centuries, the abbey was 50:03
transformed. A new closter was built on 50:05
the site of the old one in the 18th 50:08
century, 50:10
as well as desar. 50:12
The gardens were redesigned. 50:16
[Music] 50:18
But Clooney's greater basial church 50:22
lives on, scattered around the city. 50:24
This architectural prowess in gigantism 50:29
still radiates through its vestigages. 50:32
[Music] 50:34
It's true that relatively little 50:38
remains, but there is enough to get an 50:40
idea of what the abbey was like if one 50:42
takes the time to look and really study. 50:44
As a site, Clooney has to be earned. It 50:51
isn't just handed to you on a silver 50:54
platter. You have to dig. And when 50:55
you're given the opportunity to do so, 50:58
you'll find it's wonderful. 51:00
[Music] 51:02

Lyrics & Translation

[English]
In the heart of the French region of
Burgundy, the small town of Clooney
holds a secret. Once a gigantic church
stood here, now barely onetenth of the
original remains.
In its day, it was the largest abbey in
the world.
[Music]
Its pillars rose more than 30 m.
Its nave spans 60 m longer than
Notradamand de Pari.
300 windows illuminated the building.
It was called Mayor Ecclesia, Latin for
the largest church.
>> It was an absolutely incredible
technical feat. They managed to build
something that was simply oversized for
the era.
Built by 11th century monks in less than
70 years, it would remain Western
Christianity's largest church for five
centuries, defying all architectural
standards and declared a second Rome.
>> It looked directly to the papacy in Rome
for direction.
But after the French Revolution, this
peerless abbey was abandoned, destroyed,
and sold stone by stone.
>> The site completely deviated from the
concept of an abbey.
>> For nearly a century, archaeologists and
historians have searched for traces of
the abbey in the walls of the city.
They've discovered that the builders of
this church had mastered extraordinary
techniques.
And so they must have wanted to build
very high from from the from the word
go. You don't build vast foundations if
you're going to have a small church with
nothing on top of them.
How did the monks meet the challenge of
building such a tall and stately abbey
almost a thousand years ago? Where did
they find the materials? How did they
transport them?
[Music]
Now the greatest experts on the Clooney
Abbey, meticulous computerenerated
reconstruction and 20 years of hard work
will reveal the lost secrets of the
Mayor Ecclesia.
[Music]
Clooney Abbey was located in a remote
valley in the heart of Burgundy in
southeastern France.
Within the walls of the lost religious
city once stood the largest abbey ever
built in the Middle Ages.
More than 90% destroyed after the French
Revolution. Only a few vestigages
remained which were swallowed up by the
city that developed over the centuries.
[Music]
How could one calculate the dimensions
of the original church? What did it look
like? Today, only the large southern
transep remains with its octagonal
tower, the last vestage that proves the
once colossal size of the building.
>> Because it's the only bit of Clooney
that's left, one forgets just how
gigantic it is.
And the transcept that survives is, you
know, twice the size of the average
church, isn't it? In in its own right,
and it's only one of two transcepts.
The dimensions of the tower were unheard
of for a building from the Middle Ages.
It was more than 60 m high and
overlooked the valley.
The interior vaults measured up to 30 m.
[Music]
This tower awakened the curiosity of
historians to find the plans of the
missing abbey.
Only one existed, preciously preserved.
It dates from 1700 and was made by an
anonymous person. The precision of the
drawing is the only trace of what this
extraordinary church was like.
>> This is the oldest plan of the abbey.
the earliest testimony to its existence
in Clooney.
It was a huge monastery.
To give you an idea, from the end of the
11th to the 12th century, it housed
approximately 300 monks.
At the height of its existence, Mosame
Michelle had only 80 monks. So, it was
truly colossal in size.
[Music]
The abbey was a veritable city that
stretched over 15 hectares, almost half
the size of today's Vatican with
buildings that were oversized for the
time.
Some are still visible in the city, such
as the Miller
and the inn.
Yet, the highlight of the map that
intrigued the researchers was the size
of the aashial church in the middle.
When you look at the scale of the large
aial church, you see that it was
colossal.
>> It was 187 m long. To put it into proper
perspective, it was 60 m longer than
Notradam de Par.
The church was bigger than Notraam de
Pari, St. Peter's Basilica in Rome,
Chartra Cathedral, and the Basilica of
Sandini.
In size, it beat any other church in the
Middle Ages.
Its unrivaled length held double aisles,
11 spans, two transcepts, a small and
large with a width of 75 m. A chancel
and an apps composed of multitudes of
radiating chapels named Apicidol.
To understand the size of this
monumental church, we must go back to
the time of its creation, which began
with a key asset.
[Music]
The location on the site itself is
linked to a donation made in 1910 by the
Duke of Akiten.
He gave a plot of land, an old villa to
a handful of monks.
But he had the distinction of placing
this community under the direct
responsibility of Rome.
>> It was directly
subservient or looked directly to the
papacy in Rome for direction. So it
considered itself in a sense I suppose
to be a second row.
Its direct attachment to Rome gave it a
privileged status. But the abbey became
even more important a few years after
its creation thanks to a specific event.
They brought relics to Clooney first of
St. Peter and St. Paul and then relics
in numbers such as Clooney competed with
St. Peter's Basilica in Rome and gave
rise to a very large veneration of
relics.
One could come to venerate the relics of
St. Peter or at least pray around the
abbey. It was a bit like making a
pilgrimage to Rome. I'm slightly
exaggerating but not much. There was a
very strong connection to Rome.
>> The first church called Clooney 1
quickly became too small.
The monks built what was named Clooney 2
and little larger. But 20 years later,
this church was deemed to be too narrow.
They then built Clooney 3, the Mayo
Elesia or biggest church.
The idea was to build a church that
could perhaps accommodate up to 1,000
monks or at least a very large number of
them that were either on site or passing
through. It was absolutely vital to have
something more imposing that was really
in the image of this second Rome.
They wanted the best, the greatest, the
most beautiful, and the brightest to
manifest their faith in God, but also to
show his strength and his power. And
that the greatest, be they emperors or
even the pope, should do that with
Clooney.
At one point, Rome could not do without
the Clooney Abbey. The abbott of Clooney
was an essential person in medieval
Europe of the 11th and 12th centuries.
Abbert
Hugh of Seamur launched the construction
of Clooney 3, the Mayo Ecclesia in 1080.
His goal was to build the largest church
ever. But the monks were immediately
faced with a problem, the location.
How could a huge church be built on a
cramped site at the junction of two
rivers and on the steep slope of a
valley?
The site where Clooney was built wasn't
very good for construction. In fact, it
was somewhat of a flooded basin. To the
east, there was the Grown River that
flooded often, creating silt. The soil
was very unstable up to the level we're
at now, where natural terrain began.
>> The heart of the church had to face east
towards Jerusalem. So the monks had to
level the hillside to create a base by
removing thousands of cubic meters of
earth.
These were considerable earth works.
They had a bit of difficulty since they
were perpendicular to the slope of the
hill and consequently were forced to
carry out a number of works to try to
get it leveled.
There were layers of land that were not
very homogeneous
and the eastern parts were still quite
wet.
That's why they built extremely strong
foundations.
>> You need solid foundations to build
high. The Clooney monks understood that
very well.
The chapel of Jean de Bourbon at the
extreme southeast of the aial church was
redesigned in the 16th century.
Excavations are underway to find the
ancient foundations of the abbey led by
Fabis Orion, an archaeologist at the
center of medieval studies.
What's quite extraordinary is that we're
in the foundations. This is extremely
well-designed and well-built masonry.
And yet it wasn't visible but in the
ground buried in the foundation
trenches.
It's a very high quality construction.
The limestone blocks are perfectly cut.
Their thickness varies from 6 to 18 cm
and they're connected by mortar.
The foundations were deep because the
builders looked for hard ground to use
as a base.
Here
they were really trying to make deep
solid foundations in order to bear the
weight of the whole structure.
The depth of the foundations followed
the slope of the valley to reach the
hard rock up to 4 m deep in certain
places.
They were also extremely thick. On the
western part of the transcept, the
foundation wall was 5 m wide.
From the start, um, the foundations were
colossal. They're big and they're very
deep on a site which is not easy to
build on. And so they must have wanted
to build very high from from the from
the word go. You don't build vast
foundations if you're going to have a
small church with nothing on top of
them.
>> To stabilize the foundations, the monks
went even further.
Each wall and each pillar base were
connected by 3.5 m thick masonry.
All the structures were firmly anchored
to each other.
These walls were brought together
including those under the arches.
So from one wall to another or from one
pillar to another were foundations that
followed each other.
It's called a sill plate, which is a
kind of grid.
>> This grid stabilizing the soil was a way
of connecting the support points that
these pillars represented.
>> Once it was done, you could build
whatever walls you wanted.
>> If the ground moved, the entire building
moved, but it wouldn't fracture. There
lies the genius behind the construction.
Engineers from National
did a simulation and realized that these
foundations had enormous purpose.
Had they not been there, the monument
wouldn't have stood.
At the beginning of the 20th century, an
archaeologist also took a keen interest
in the foundations of the lost church.
American Kenneth John Conand would
change the fate of the abbey.
when he arrived everything was under
grass. There was no sign of of
foundations or anything like that. The
only thing that survived was the the
great transcept and the little eastern
transcept and the chapel bon Jean de
Borbong and so on that little group of
buildings but apart from that there
wasn't anything really visible.
>> The site had completely taken over the
area. It was a little like the Camair
temples where vegetation invades the
temples. In Clooney, the city took over
the area completely surrounding the
abbey.
[Music]
The site had completely deviated from
the concept of an abbey.
So, Conant worked for nearly 40 years to
find not only the plan, but to
reconstruct the lost volumes of this
exceptional building.
Using rare artist drawings from the 18th
century showing the abbey and its
church, Kenneth John Conand had only one
obsession to find the exact dimensions
of the building.
To do so, he analyzed the foundations,
their thickness, and their composition.
Finally drawing hundreds of plans which
revealed the abbey in volume for the
first time.
[Music]
Conant was the one who rediscovered the
Clooney Abbey. He was the first to have
proposed reconstitutions of the aial
church in all its original and later
splendor.
[Music]
Through his research, Conan discovered
the entire size of the building.
The nave of the church was composed of a
double span punctuated by 18 monumental
pillars.
[Music]
It also featured a transcept itself
followed by a smaller one.
Finally, there was the chancel with 10
pillars that formed an ambulatory.
Three floors of windows bathed the
church in light
and the vaults were 30 m high.
[Music]
In the 11th century, no other church
matched it in height and dimensions. It
was the largest, highest, and brightest.
But how did the monks manage to create
such a masterpiece using the techniques
of the Middle Ages?
The 10th century was the golden age of
Romanesque arts. Churches were modest in
size, not exceeding 20 m tall with thick
walls and small windows, far from what
the monks wished to achieve.
>> The churches of the 11th century were
darker, usually because their windows
were cut into the walls of the tribunes.
The naves were rarely lit directly.
The churches were rather squat.
The monks of Clooney decided to raise
the walls
to build very high vaults and to add
many windows.
[Music]
At the time, the vaults had a
semic-ircular arched shape typical of
Romanesque art. The semicircle supported
the weight. The diameter was therefore
equal to the width of the vault. The
height of the vault was the radius.
To increase the height, the nave had to
be widened. But the bigger it got, the
more the forces at hand weakened the
structure.
To build higher, they had to find a
solution other than the semic-ircular
arch.
They were driven by the necessity of
solving this technological problem to
guarantee the stability of the building.
At one point, the genius idea of using
Gothic arches must have come into the
mind of the site manager as a way to
solve this issue.
The Gothic arch is two half circles with
centers located at the extremities of
the vault.
They intersect and this forms a Gothic
arch.
The width is no longer related to the
diameter as it is for the semic-ircular
arch. It can reach 2/3 of the arch.
It's therefore possible to build higher
than with a semic-ircular arch.
>> The Gothic arch existed before Clooney.
It wasn't conceived specifically for
Cooney, but it was used because of its
interesting characteristics.
In the Romanesque style, all arches were
systematically semic-ircular.
For Clooney, however, they could not be
used for reasons of stability.
At that time, it was quite innovative
because it would allow the weight to be
better distributed over fully volted
parts.
With semic-ircular arches, the weight is
evenly distributed horizontally and
vertically. This requires thick walls to
prevent them from spreading under
pressure.
By breaking the arch into two half
circles, the horizontal component of the
weight is reduced and carried over to
the vertical component.
As a result, the walls can be thinner
and higher without the risk of
spreading.
From the moment these walls could be
higher in elevation, they could also be
cut more easily to create bay windows.
It was these openings that allow light
into all the vessels that made up the
nave and the aisles of Clooney 3.
[Music]
It's clear that behind what appears to
us to be essentially new forms, there
was above all technological research
at a level we would deem quite advanced
today.
But Gothic arches were not enough to
flood the nave with light while
maintaining the stability of the
building. It is this church plan that
allowed the architects to grasp the
level of mastery with which the Clooney
monks understood the balance of forces.
This is a cross-section of the large
nave of Clooney 3.
It was composed of a central aisle and a
double aisle.
The forces were redistributed by
staggering the aisles.
This shared distribution of lateral
force was achieved through the stability
of the outer walls with powerful
buttresses.
So it was a massive structure but a
particularly wellbalanced one.
There was a genuine effort made to
understand these forces.
These people displayed an exceptional
level of conceptualization.
There was a clear architectural and
engineering approach
typical of Romanes. The central naves
were buttressed with aisles. Here the
size of the building is such that the
monks added a third aisle maintained by
powerful outer buttresses.
The monks pushed Romanes art to its
limits.
The three floors of successive Gothic
arch vaults rose to 29.5 m, 17 m, and 10
m, allowing for a perfect balancing of
forces.
It was then possible to cut rows of
windows on each floor.
These windows represented a 45% void
compared to the walls.
[Music]
There were several rows of overlaid
windows which obviously allowed them to
create an unrivaled luminosity inside.
This is to evoke another spirituality
that of the divine that floods the place
of contemplation with his light.
[Music]
At that time, people didn't dare open
walls under vaults like this, especially
in a building as important as the Mayor
Elesia. So, this was very important and
very bold, and it foreshadowed what
Gothic architecture would later become.
>> In Gothic art, the structure carries the
building, not the walls. In Kuni, the
monks pushed the thought process of
force distribution to an extreme in
order to exceed the heights allowed in
Romanesque art right down to details
essential to balance.
This is notably the case with the
position of the pillars.
This narrowing, very subtle at each
level, allowed the springing point of
the vaults to be brought into the design
of the building and thus offer more
stability.
And so the oblique lateral strain was
better contained in the design of the
building.
The building was a balance between force
applied vertically and horizontally.
Butresses, arches, and the position of
pillars. Everything was present to allow
the monks to build a gigantic church.
[Music]
However, because the building was also
subject to torsional movement, the monks
paid attention to the slabs that
supported the top floor.
>> There was a whole system of staples that
actually locked the inner bands, the
last band at the top of the transcept.
So, all the parts were actually sealed
by these metal staples.
These were large staples 50 cm in length
by 2 cm in width and across.
The building was so large that they had
to take every precaution and resort to
any technique imaginable to achieve
stability and avoid deformation.
[Music]
But that wasn't enough. The monks were
still concerned about the pressure put
on the walls by the vault. So they
placed large iron bars along the entire
length of the nave.
Across the transcept there were these
bars of metal which held the thing taut.
These huge tier horn affair had to hold
the walls from from falling outwards.
You know
>> if they did it it was because there was
a need. So it's clear that the building
called for this kind of buttress. The
project was rather bold anyway.
Everyone in the middle ages knew Clooney
and the builders of the great cathedrals
knew it too.
They knew what the advantages or
disadvantages of various strategies
were.
That's why the Gothic arch implemented
in Clooney was reproduced in the great
cathedrals. The use of iron with staples
was used in Gothic architecture and so
on.
The abbey was splendid, grandiose, and
impressive.
The first stone was laid on October
25th, 1088. The monks began with the
southern arm of the great transep, the
only part that remains today. The site
then moved south to north and then to
the west.
[Music]
On the walls of the church, you could
see a multitude of holes left by the
workers scaffolding. These are called
putlog holes.
>> Putlog holes are small orififices that
were made into the wall at the time of
construction. That's how they could
stack the beams, trays, scaffolding, and
so on.
Their location provides information on
the evolution of the construction site,
notably the part that survived the
destruction, the large southern
transcept of the abbey.
We can see that the putlog holes which
are aligned horizontally on the first
two spans are not on the third.
There is a difference of 30 to 40 cm.
This is a sign that construction
stopped. What happened?
If we look at the third span in more
detail, the three highest windows are
not aligned with those just below.
Moreover, the band that marks the floor
suddenly stops and does not continue on
the third span.
All of these clues help us understand
what happened on the site at that time.
[Music]
There was a change of purpose. At first,
they set out to build a vaulted church
with 20 m under the vaults in order for
it to be lit directly.
But at this stage of construction, in
the middle of the transcept, they
decided to build 10 m higher. Plans were
changed. You can clearly see it in the
transcept.
[Music]
The first dome was 20 m high, the second
30 m, and the third was supposed to have
been 20 m high.
But the monks decided to go higher. By
placing this third dome 30 m high, they
were forced to shift the windows to the
north to leave room for the support
pillar.
[Music]
In their dream of gigantism, raw
material was essential. And in that
respect, the location of the abbey was
perfect.
>> For materials, it was perfect.
Everything needed was on site, both in
abundance and quality. That's
exceptional. There were limestone
quaries.
If you cook limestone, you get lime,
which is the binder needed to build.
They had sand from the grown river and
large quantities of clay to make the
floors, tiles, etc.
>> Not to mention, the valley was
completely covered with forests.
Near the construction site, less than 3
km away, were a multitude of quaries
with an abundance of stones.
[Music]
The farthest one was 18 km away. It's
the last still visible today.
The monks extracted white limestone
called piselite limestone.
We're here at the library. This is one
of the rare sources of soft stones in
the region. We know that stone was
extracted for sculpture.
The other quaries were composed of hard
stones used for construction.
There were three types of limestone with
different physical characteristics,
micrite, oyte and krenoidal.
There was also aros, a kind of
sandstone.
>> The programs were deliberately very bold
in terms of budget and technique. So
they looked for the best stone possible,
large sheets of bedrock that could make
big walls.
>> The most beautiful stones were cut
directly on site and placed so that they
were visible on the exterior.
>> The walls were made with two facades
that were relatively similar with rubble
stone cut more or less finely depending
on the area.
And in the middle was a mixture of
coarse mortar with all types of stone
waste to create a stable uniform block.
The wider it was, the higher it could
go.
>> It was an absolutely incredible
technical feat. They managed to build
something that was simply oversized for
the era with fairly simple means as the
walls were made with basic rubble.
That's how buildings had been
constructed since antiquity.
>> From these quaries, the monks extracted
a single stone 6 m long, 3 m high, and
45 cm thick. The tempanum.
It was placed at the entrance of the
large gate to impress visitors.
It was an extraordinary block in terms
of size considering the supply of the
local quaries.
>> Then it had to be moved which was also a
technical feat.
>> The idea was to use intelligence rather
than strength.
To carry the stone, the monks installed
a ramp that compensated for the slope of
the valley over 10 m in elevation.
The tempanum was then rolled on logs to
the large gate.
It was then lifted up using a hoisting
device called a jack, which reduced the
weight of the stone by a factor of 100
using the principle of traction levers.
The 28 ton stone was then placed on its
base.
>> This huge temp was lifted vertically on
these jams and was then sculpted.
They didn't want to take the risk of
creating that sculpture of Christ in his
glory before setting it up and digging
into the mass of the tempenum. Because
of the 45 cm thickness, they dug up to
40 cm to give depth to the sculpture.
[Music]
>> Christ was surrounded by four angels
whose remains found on the site show a
quality of sculpture that was unmatched
at the time.
In certain areas of the tempanum, only 5
cm of stone thickness remained.
>> From that moment on, an immense gate was
built that measured 14 m wide at the
base and 20 m high.
An architeure was placed at the top to
complete the composition.
ed as a genuine triumphal arch.
>> This was really in line with the idea
that Clooney would be restoring the
ancient world and Rome.
[Music]
>> The quality of the sculpture was just
breathtaking. When you came in through
the west door under that lintil that you
know and all the sculpture of the west
door and you looked down the whole
length of the church, what you saw was
the enormous Christ in the apps painted.
[Music]
There were more than,200 capitals
inside. which entails a gigantic number
of highquality decorations.
These were large capitals, 80 cm wide by
80 cm high. It was a colossal building,
the scale of which was quite remarkable.
>> Only eight capitals were found almost
intact. They adorned the pillars of the
ambulatory in the chancel.
Here
again the sculpture was carved with a
lot of depth so as to play with shadow
and light.
The majority of the capitals had
Corinthian themes. They were modeled on
Corinthian capitals. The reference to
antiquity was tremendous.
In antiquity you had temples with
columns and Corinthian capitals.
In the Clooney 3, they replicated the
colonade and borrowed Roman marble
columns that they trimmed and installed
around the chancel.
So, Clooney 3 was representative of
ancient Rome in all its splendor.
Above all, the monks wanted monumental
architecture.
With that 2 m diameter, the vestigages
of the pillars that punctuated the nave
bore witness to this desire.
The choice of the stones that composed
them wasn't the result of chance.
They didn't put just any stone in any
place. The base of the first pillars was
made of micrite limestone. With
moisture, the open transcept and the
destruction these stones degraded. Next
was a mixture of aros and limestone. Why
did they use micrite limestone which is
not particularly known for being of good
quality? Well, that stone is interesting
because it's very resistant to
compression. What was above it was
extremely heavy. the pillars, the
vaults, the dome all weighed on the
pillars. So they chose this stone to
support the vertical load.
>> Likewise, when the composition of the
walls of the still existent transcept is
analyzed, each stone has its function.
At the base, micrite limestone to
support the weight. In the middle,
strong and rigid sandstone. and at the
top soft limestone for the sculpted
capitals.
[Music]
At this point, 30 years had passed since
the first construction of the great
church Lamayo Ecclesia. The Clooney
Order was at the height of its power.
The Abbotts were in permanent contact
with the emperors, sovereigns, leading
figures of the world, and the papacy.
The Abbey couldn't be overlooked.
Gradually, it created what we called an
empire. They called it a religious
order, but it truly was an empire.
Today, for a company or a firm, it would
be called an empire. It was an abbey
that had subsidiaries, so to speak, and
throughout Europe, from England to
Italy, from Spain to Poland. It had an
enormous influence, spiritual of course,
but also temporal.
[Music]
More than 800 monasteries were created
and directly attached to the abbey. The
order was based on the rule of St.
Benedict, a return to spiritual life and
prayer. It resonated with world leaders.
The Abbotts also put into place an
entire strategy around the worship of
the dead, the feast of the dead, and the
need to pray for the dead. They
multiplied the altars, held more and
more masses for the souls of the
deceased and in each mass obviously the
coffers of the abbey increased.
Clooney had vast wealth at this time and
certain great sponsors
and it's clearly was the kings of of
Leyon and Castile. uh their their great
gold treasury which they the tribute
which which came to Clooney annually
from the northwest of Spain uh meant
that the coffers of Clooney were
bursting
and uh this incredibly ambitious
uh church project was was undertaken.
Clooney had colossal means. It was a
building that was erected very quickly.
>> Perhaps too quickly because in 11:25 an
event changed the structure of the
building.
>> In 11:25, the vault of the nave
allegedly collapsed.
>> One of the vaults most likely collapsed.
We don't know where.
>> It could be the great nave. It could be
an aisle. Could just be a little aisle
or a chapel or something. You know, it's
not it's not at all clear. Obviously,
the monks were devastated. Their dream
of greatness and prestige was ruined.
>> The monks had to review their plans and
determine what happened. How could a
building that had been so well thought
out be fragile? What was the mistake?
>> They didn't anticipate the fact that the
nave was very long.
The entire length of the nave had been
built using the same vault and the same
walls. But given that length, there was
a certain flexibility to it.
For example, if you take a pencil that's
5 cm long and you try to break it,
that's hard to do. But with a 30 cm
pencil, all it takes is a little snap
and you break it. So, what did they do
in the Middle Ages? They constantly
monitored the vaults.
The monks placed steep and narrow
staircases in the thick walls of the
abbey approximately 40 m in height.
From there, the monks could control the
structure. They might have noticed that
the vaults were fragile despite all of
their precautions.
What we do know is that they reinforce
the vault with walls called buttress
walls
in order to transfer some of the weight
and stabilize the vault of the central
aisle.
And to avoid having massive walls that
would change the perspective a little,
an arch was hollowed out in them.
The arches thus counterbalanced the
forces applied by the vaults onto the
walls. These arches would later emerge
in Gothic churches as flying buttresses.
>> Clooney 3 was really the transitional
building between typical classic
Romanesque art and Gothic art that would
flourish a few decades later.
It's traditionally believed that Gothic
art was developed in the Parisian region
and indeed most of the great monuments
of this period are concentrated there.
But the genius of the techniques that
allowed Gothic art to blossom really
took place in Clooney around 11:30.
In 1095, Pope Innocent II came to
consecrate the church. It wasn't
entirely finished. The last stone wasn't
laid until 11:30,
but as soon as it was completed, the
monks decided to build a 38 m long narex
that would end with two large towers
called barabans, culminating at 17 1/2
m.
There was a problem. The hill had to be
dug once again to integrate the
extension.
>> They wanted the narthx to extend into
the hill. topography.
>> The topography of the site and the
choice of location made by the monks at
the end of construction led to the fact
that one entered the church by going
down the steps, thus bowing to the saint
of saints represented by the magnificent
chancel of Clooney 3.
It was in Clooney that the legendary
Narthx was created, an anti-urch located
right in the front of the nave called
Galile because it refers to a very
specific liturgy pertaining to Easter
and the observance of Easter.
[Music]
>> Easter celebrates the resurrection of
Jesus. In all its grander, the front of
the Nate symbolized the passage to
eternal life.
[Music]
The aial church was finally finished. It
had risen from the earth in less than 70
years.
It imposed its power by its gigantism
dominating the center of the abbey.
This religious city was surrounded by
walls.
Its ramparts rose to more than 8 m and
were made of defensive towers and gates.
[Music]
The walls of the abbey weren't there
simply for the prestige. They were also
meant to protect in case of an attack
and there were several. And then you had
the city around the abbey along with the
walls of the city. So the abbey was a
small town within the town of Clooney.
When the abbey expanded, the
fortifications were enlarged as well.
And gradually by expanding,
it brought more and more people to these
sites.
Pilgrims had to be accommodated. So, a
hotel was built.
Visiting guests needed accommodating,
too.
We tend to forget that an abbey isn't
just a church, a closter, and a few
buildings. It's an entire economic and
cultural complex.
Very quickly the question of water
arose. How could it be provided to the
community? The monks resorted to two
rivers located on either side of the
abbey. The Medas and the Grun.
But this required making adjustments.
The medasau is a small stream that
originated west of Clooney and was
channeled under the city of Clooney. It
was used for the hydraulics of the
monastery and part of the city.
The water from the source of this stream
was transported into the monastery as
drinking water.
It was brought to the fountain of the
cloister and from there water was
distributed to the kitchen, to other
fountains and perhaps to the baths.
The monks used gravity. The slope went
from west to east and the midass flowed
naturally into the gon. The fountain of
the closter that received the water was
the highest in the abbey.
Once filled, it supplied the various
locations.
Using the drop in elevation, the monks
increased the pressure and made the
water gush.
The midas also served as sewer water. A
parallel network was to be created
evacuating sewage.
There were sewer systems that were
several hundred meters long.
Running water was injected into them to
carry away the waste.
There were flushing systems upstream of
the monastic latrines
which were large longitudinal buildings.
In these upstream systems, the valves
were opened and the fecal matter was
sent further downstream.
Very quickly, the abbey expanded towards
the GR and the monks diverted the course
of the river. They set up water
retention ponds upstream and downstream
of the river by building 5 m high and
370 m long dams capable of holding 200
hectares of water. In doing so, they
created a diverted canal that ran along
the valley and irrigated the entire
abbey. It was one of the most complex
hydraulic systems ever built in the
Middle Ages.
>> Clooney took a natural water system and
changed it into a completely artificial
network.
There was no natural water passing
through the city or the abbey at all.
[Music]
The monks set up 187 mills along the Gun
and inside the abbey which brought them
a colossal income. It was one of the
greatest senori of the Middle Ages.
In the middle ages, mastering water was
of course a sign of power and
technological knowhow.
The monks of Clooney were no exception.
Beyond the domestic dimension, there's a
spiritual dimension to water that helped
demonstrate the richness of the abbey.
The Clooney Abbey prospered for five
centuries thanks to a succession of
powerful amb.
The abbey started to decline in the 15th
century. In the 16th century, it was no
longer attached to Rome and lost a large
part of its income. In 1789, the French
Revolution brought about the end of the
abbey with its sale in 1798.
>> The Bashel church was sold in lots to
material traders and developers
who stone after stone patiently
dismantled the entire building.
In this huge church that was a
masterpiece of architecture, they only
saw a pile of stones that would allow
them to get richer.
>> The town encroached on a large part of
the abbey, namely the land located close
to the village.
As a result, there is currently an
interweaving between the current town
and the historic buildings of the abbey.
The site completely deviated from the
concept of an abbey.
>> Strolling through the city, one can see
a multitude of medieval houses, some of
which have pieces of the great abbey in
their walls.
In the masonry of the houses and in
private owned gardens, we often see
elements of a sculpture, a piece of
capital, a fragment of a portal or a
statueette that came from this great
church.
Over the centuries, the abbey was
transformed. A new closter was built on
the site of the old one in the 18th
century,
as well as desar.
The gardens were redesigned.
[Music]
But Clooney's greater basial church
lives on, scattered around the city.
This architectural prowess in gigantism
still radiates through its vestigages.
[Music]
It's true that relatively little
remains, but there is enough to get an
idea of what the abbey was like if one
takes the time to look and really study.
As a site, Clooney has to be earned. It
isn't just handed to you on a silver
platter. You have to dig. And when
you're given the opportunity to do so,
you'll find it's wonderful.
[Music]
Every detail immerses you in the
glorious past of this prestigious order.
It's thanks to the power and fervor of
the abbotts that the abbey was able to
compete with the greatest buildings to
the point of being compared to Rome.
By wanting to create bigger and higher,
these monk builders advance the
architecture of the Middle Ages. Today,
all you have to do is let yourself be
carried by these premises to understand
the scale of this project and its
challenges.
Heat. Heat.
