London's architecture is worth studying because the city has been rebuilt again and again on its old ground. The Great Fire of 1666, which destroyed about nine tenths of the city, was a turning point. Wren's grid plan was set aside: the city was rebuilt on its medieval streets, under a 1667 act asking for brick houses of uniform height and plot size. Pevsner praised Wren's dome for St Paul's as among the most perfect in the world. Most of the city walls came down in the 18th century so London could grow; Victorian London built the world's first underground railway. John Nash laid out Regent Street with James Burton and remodelled Buckingham House into Buckingham Palace.
