All Saints is notable primarily for its excellent medieval wall paintings. The oldest - at the west end of the aisles - date to the late 13th century, and are thought to represent the 12 apostles. Each apostle is portrayed life sized, with a covering canopy.
These figures tend to be overshadowed by a profusion of later heraldic figures. Some of these figures may be in honour of the Loryng family, local lords in the late 14th century. The church contains a 14th century memorial to Sir Nigel Loryng (d. 1386), one of the founding members of the Order of the Garter and hero of the Battle of Sluys.
