The Great Hall did not completely escape damage in the Great Fire of London in 1666; it was partially restored (with a flat roof) in 1670. The present grand entrance (the east wing of the south front), in "Hindoostani Gothic", was added in 1788 by George Dance. A more extensive restoration than that in 1670 was completed in 1866 by the City of London architect Sir Horace Jones, who added a new timber roof in close keeping with the original hammerbeam ceiling. This replacement was destroyed during the Second Great Fire of London on the night of 29/30 December 1940, the result of a Luftwaffe fire-raid. It was replaced in 1954 during works designed by Sir Giles Gilbert Scott, though the original hammerbeam design was not retained.
