Sir Christopher Wren was 33 years old and near the beginning of his career as an architect when the Great Fire of London in 1666 destroyed many of the city's public buildings, including 88 of its parish churches. Wren's office was commissioned to build 51 replacement churches and St Paul's Cathedral. Many of these buildings survive to this day; others have been substantially altered or rebuilt. Some others were completely or partially destroyed during the German Blitz of 1940âÂÂ41; others were demolished for different reasons.
Many of Wren's churches were demolished as the population of the City of London declined in the 19th century and more were destroyed or damaged during the Blitz.
The Blitz in 1940âÂÂ1941 damaged nearly all the churches in the City of London and many were nearly destroyed leaving just the outer walls and tower. However most of them were rebuilt to Wren's original design.
These churches were destroyed in the Blitz or demolished in the 19th century. Only their towers remained with perhaps a short section of the outer wall. They are no longer working churches.
The population of the City of London declined sharply in the 19th century, and the Union of Benefices Act 1860 reduced the number of parish churches. The surplus churches were demolished.
These churches were destroyed in the Blitz and their ruins demolished afterwards.
These churches were outside the area of the Great Fire of London.
