Over the last millennium, a striking cathedral dedicated to St Paul has been a precious jewel for the city of London. It sits at the top of Ludgate Hill, the highest point in the City of London. What is now St Paul's Cathedral, London, is an Anglican cathedral, the seat of the Bishop of London and the mother church of the Diocese of London. Regularly, as the Cathedral is at the center of numerous nationwide events, innovations have been scrutinized and drastic new thoughts have found expression under the iconic dome. Bearing all those occasions in mind, it is certain that they would have left behind some physical evidence and reverberations in the imperceptible preservation of the Cathedral itself. There is a long history of St. Paul's Cathedrals dating back thousands of years from the initial construction of the first church to today's St. Paul's Cathedral, which is the fourth cathedral built on the site. The first Christian cathedral to be built on the site, dedicated to Saint Paul, was in 604 AD under the reign of King Æthelberht I. Historical reports show that the initial church was destroyed by fire. In 675-685 AD the church was replaced and demolished by Viking raiders in 962, and another was erected in 1087 AD to stand on the same site. At the end of the 11th century the famous Cathedral of San Paolo Vecchio was built. of the Caen stone. This was one of the largest structures in England at that time, with its spire taller than the existing cathedral dome. After the King of England, Henry VIII (1491 – 1547) separated the Church of England from the authority of the Pope, the Crown took control of the church in the country. Therefore, after the English Reformation of the 16th century, the Crown ordered... middle of paper... to suffer the civil war that broke out in 1642 in England. A few months after Wren's return from his self-instructional trip to France, in May 1666, he put forward a very radical suggestion for the restoration of the cathedral, instead of that, patched up with the proposals of the older men of the Commission, Sir John Denham the Surveyor, John Webb and Sir Roger Pratt. Wren suggested modifying the interior of the nave as well as the exterior and replacing the nave vault with saucer domes. "He noticed that it would be easy to do it in the Roman way, so as to follow the Gothic rudeness of the old design." In Wren's report there were also practical proposals for the erection of the new dome over the old tower, which would be used as scaffolding and then demolished when completed, a method which served him well during his trip abroad, a method that could save time and money.
