The interior was renovated or repaired four times since 1800. It was repaired by Henry Fairfax in 1838-39, again after the Civil War, and was significantly remodeled in 1908. The most extensive renovations were completed in 1959. At that time, the galleries - which had been anticipated in Wren's design, but were omitted from the original construction - were finally installed and a new chancel was added. The structure of the church, except for repairs of war damage and the chancel addition, is the original 1769 construction.
