Church of St. Peter and St. Paul

The Church of St. Peter and St. Paul is a parish church located in Burgh Castle. The west tower dates from the late 11th century, while the nave and chancel, which retain a 13th-century character, were remodeled in the 15th century. The north aisle was added in 1847, and the south porch was constructed in 1857. The church is built from a combination of Quaternary and Quarry flint and chert, with Lincolnshire Limestone ashlar dressings and some brick, and it features partly rendered surfaces and slate roofs.

The tower is circular and consists of three stages, topped with a crenellated parapet. It has a lancet window on the west side, and although there are no ringing chamber windows, the belfry has lancets with brick surrounds. The tower's top has been rebuilt in brick. The nave is supported by diagonal stepped buttresses, and the gabled porch features a moulded entrance arch. On the south side of the nave, there are two two-light Perpendicular windows flanking a single lancet, and the south flank has stepped buttresses. The lean-to north aisle is pierced by two-light Perpendicular windows, while the chancel has two three-light Perpendicular windows under square heads and a three-light east window, with diagonal stepped buttresses at the east end.

Inside, the church features a tall chamfered tower arch and a three-bay north arcade in a 14th-century style, with tall plinths and piers formed of four lobes with hollows between, and wave moulded arches. The nave roof is scissor braced with renewed timbers and a decorated wall plate. The font, believed to date from 1387, is octagonal and features four crouching lions on the stem, with angels beneath the bowl and alternating panels of lions and shield-bearing angels. There are two high splayed windows above the south door, and the brick rood stairs are blocked at the top. The chancel arch is wave, hollow, and chamfered with circular responds, and the chancel contains remains of one irregular wall arch on both the north and south sides, with the southern arch interrupted to allow for a window. Additionally, there are bench sedilia and a trefoiled piscina.
