St Leonard's is set in an oval of period houses, creating an atmosphere not unlike a cathedral close. During the Civil War, the church was used by Parliamentary soldiers as a store for ammunition. A cannon shot caused the ammunition to explode, starting a devastating fire that swept through the town.
The church -- and town -- was restored. The major church restoration was executed under the direction of Rev George Bellett, a 19th-century rector whose monument stands within the church he helped to create.
The sheer size and width of the church are breathtaking, of almost cathedral proportions. The interior features extremely fine woodwork, stonework, tiles, and colourful stained glass. Among the numerous monuments is a quartet of fascinating memorials dated between 1692-1707, built of cast iron.
St Leonards is no longer in regular use for worship and is cared for by the Churches Conservation Trust.
