[Music] we're in st. Paul's Cathedral in London this huge Church map so beautifully to the history of Britain the first church was built here by the east saxons in the early six hundreds they would have been just recently Christian and then that church was burned down and another church was built which was destroyed by the Vikings during the Viking invasions and then that was replaced by a church that was built by the Normans after they invaded from France in 1066 and that church survived until the 17th century and at that point it really wasn't in good shape the English Civil War had just happened the Reformation had happened in fact during the civil war the church was used as a stable so horses were kept here and apparently there was a market here and a road running through the transept so the church was in tremendous disrepair but when the monarchy was restored and charles ii took the throne he saw this church as an expression of his authority as king and wanted to see it restored as well so Christopher Wren who was at that point a professor of astronomy at Oxford University and a scientist he was a mathematician an overall brilliant Renaissance man charles ii called on him to restore the church that was here and to rebuild parts of it so in 1665 Christopher Wren visited Paris he had an interview with Bernini who was there to consult about the architecture of the Louvre and he came back to England wanting to replicate the grand classical style that he saw in Paris and he came back armed with engravings and that was important because those engravings showed not only the great architecture in France but also the great architecture in Italy and Italy was a country he did not visit but nevertheless he understood the architecture that was being produced there and we think that there are direct references back to for instance Michelangelo's dome at st. Peter's and some of the designs of the Louvre in Paris as well as work by Bohr emini and some of the other great architects of the Renaissance and Baroque periods although was asked to supply designs for rebuilding and restoring this church there was a great Cataclysm ik event that allowed him to entirely rebuild it and that was the Great Fire of London in 1666 London was at that point dense with small wooden houses there had been a long hot dry summer and there was also a strong wind and this made what was initially a small fire grow uncontrollably and was not put out for between four and five days it destroyed most of what we think of as the city of London that is the oldest part of London the medieval city of London was gone the fire destroyed more than 13 thousand houses 87 churches as well as the church that was here what we now refer to as old st. Paul's it took years for the city to recover and Wren was brought in to the ruins of the church to see if it could be saved ultimately he said no and the old Norman Church was taken down and Wren was able to reconsider church from scratch as well as we conceived it within the fabric of a city that he also sought to design Wren reconceived a new city of London with wide streets and boulevards he didn't get to build that city but he did get to build st. pauls as well as dozens and dozens of parish churches that dot the city of London today almost 100 churches in the city of London alone and so although he was not an architect that was able to completely reconstruct London from whole cloth he did have a major permanent impact standing here it's impossible not to think about the church that from Monday conceived in Rome for the Vatican the new Church of st. Peter's it reminds me of that because of the scale of the building and the classicism of the building and if Wren had had his way one of his initial designs was even more closely aligned with Bramante it was a Greek cross that is instead of it being originally conceived of as a basilica with a long nave and in this case with a long choir it was equidistant on all four protruding sides with the dome in the center Wren was fascinated by the symbolic power and at the majesty of the dome and would build the first great dome in England rival st. Peter's in its size it rivals other great domed buildings like Hagia Sophia and the Pantheon in Rome or Brunelleschi's Great Dome in Florence this is enormous and it actually Dwarfs in some ways the rest of the structure the architecture of this building is a kind of late Renaissance Baroque structure that is borrowing both from the Italian Renaissance and in turn from antiquity that first idea of wrens to build a Greek cross across with equal arms was very classical in its inspiration but Wren was not allowed to build that the clergy here were not happy with the idea of a church that didn't look like a traditional English church they wanted to leave that was more traditional something that took the shape of a basilica with a long nave so Wren ended up building something that was somewhat of a compromise it has the enormous dome that he wanted in many ways it has the feel of a centrally planned church because of the enormity of the dome over the crossing but the church officials did get that extended East End the choir that they wanted and they did get an extended nave toward the west but wrens will really dominates on the exterior of the church which is so classicizing and makes a real effort to hide some of the more medieval structural elements of the church to create a seamless classical exterior Wren relied on flying buttresses but as you said he covered them up so obviously foremost on wrens mine must have been how to support a dome of this enormous width that must have an enormous weight if you look closely at the crossing you can see vast piers these are solid masonry structures that really do the weight bearing of this dome but as you go up the stone itself is more complex than it seems there are three structures here when you look up at the dome from below you're seeing a masonry dome but that's doing nothing but supporting itself because when you look at this building from the outside you also notice that there is a very hi lantern atop which is also masonry and that sits on what is in fact a lead roof and so when you look at a cross-section what you're seeing is first the masonry dome what you see from underneath then there's a conical brick wall it's about a foot and a half thick and that is built to support that masonry lantern on top above that the outer shell is made of lead which is supported by Timbers and there are also iron chains which circle the dome which work to support it you can almost think of it as a kind of belt that's tightened at the bottom of the dome itself to keep the weight from pushing outward with a kind of lateral thrust that is a real concern any time somebody builds an arch or a dome and I think we're so used to seeing domes that it might be hard to imagine how amazingly beautiful and Magisterial this looked when it was first raised so many ways this church is a negotiation between officials of the church and the architect to the needs and expectations of the monarchs that ruled when this church was being built but also that had to do with the very core use of this building this was built within a century and a half of King Henry the 8th breaking away from the church in Rome from the papacy and establishing the Church of England and so what we're looking at is a building that embodies a new type of church for a new Church of England we've just stepped out of st. Paul's Cathedral in order to look at the south transept from the outside in the pediment you can see a large bird this is meant to represent a phoenix mythological creature that was believed to live for a very long time and at the end of its life it was burned until there was nothing but ashes and then a young Phoenix would arise and so it had to do with his rebirth from fire and of course what a perfect metaphor for this church and for the Christian idea of the resurrection generally of life after death but there's a special story that goes along with this that has to do with Sir Christopher Wren when was planning the Cathedral he marked out the center of the dome and asked a workman to bring him a stone to mark that exact center the workman brought him a stone and when Wren turned it over this is all according to legend on that stone which turned out to be a gravestone was the word recirc um which means resurrection it's a common word we see on tombstones in Latin and so that word can be found inscribed just below the Phoenix on the transept and so we have this idea of Christian resurrection but also the idea of the resurrection of this church after the great fire in 1666 [Music]
