London, with it's ancient Roman roots, also had early Christian roots. The oldest known Bishop of London was Restitutus in the early 300s. It is believed he might have attended the Council of Nicaea, that all important early Church council that, among other things, established that Jesus was Man and God and gave the wording of the familiar Nicene Creed still spoken in Catholic churches today. It is not known if St. Paul's was dedicated at this time or not, but the building of a cathedral on that site began in 604, but it burned down in 675. In 962, it was built again and after the Norman Conquest a new cathedal was ordered and work began in 1087 on the same spot, completed in 1310. That's some union. It had a central spire and this is the cathedral my fictional detective, Crispin Guest, would have known well (below). In 1666, the Great Fire of London destroyed it and the more familiar Christopher Wren design with the soaring dome was begun in 1675 and finished in 1710, the cathedral we know today.
