Church of St. Mary

The Church of St. Mary is a medieval parish church, substantially restored in 1859. It is built of flint, chert, and Lincolnshire limestone with a slate roof dating to 1824. The church comprises a west tower, a nave, a chancel, a south porch, and the ruins of a north chapel.

The unbuttressed west tower is of three stages, built in coursed flint with stone dressings. It has a plain parapet, a gargoyle on the south side, and a projecting stair turret to the north. A two-centred west window is spanned by a central wooden mullion, and the wide bell openings have multi-cusped heads. A tablet on the south wall commemorates William Load, who died in 1734, and his wife Grace, who died in 1739.

The nave is of rendered coursed flint, with some iron conglomerate, and has eaves rebuilt in brick. Two 19th-century south windows provide two and three lights respectively. The south porch is constructed of rendered flint with stone dressings, partially rebuilt in brick. It features a plain chamfered arch and trefoil-headed lights on each side, as well as a continuous moulded doorway. The ledged and battened door has a lozenge-shaped iron plate with a ring, lattice bracing to the rear dated 174-, and a wooden lock dated 1748.

The east and south walls of the chancel are of coursed flint and iron conglomerate, with conglomerate quoins. The eaves to the south have been rebuilt in brick, and there is a central stepped buttress on the south side. A trefoil-headed light is positioned to the right and a two-light window is positioned to the left, both beneath square heads. Some bricks are visible in the east gable, which has been rebuilt with knapped flint, concealing an original blocked opening. A smaller 19th-century window of three lights with panel tracery has been inserted. The north chancel wall has been rebuilt in brick over a flint base, and contains a two-light window under a square head.

The north chapel is in ruins, with a flint north wall and gable showing an opening with internal brick dressings. Foundations are visible for the west and east walls, and the original arch to the nave has been blocked with an inserted 19th-century window featuring 'Y' tracery.

Inside the church, a 19th-century king post roof is present. The tower arch has chamfered jambs, and the chancel arch is pointed and segmental, with polygonal shafts. A doorway leads to the former roof loft to the north, and a wide piscina features a cinquefoil head and round shafts. The Sanctuary contains 17th-century panelling. The font is plain and octagonal, set on an octagonal stem, and is covered by a 17th-century cover. The pulpit, likely from the 18th century, is adorned with a figurehead of a winged female. A William IV achievement and an 1839 Tithe Commutation map are located above the north door. Brass memorial inscriptions are set in marble slabs on the chancel floor, commemorating William Lumnor, who died in 1481 (builder of Mannington Hall), and Margaret, daughter of Thomas Monseus, who died in 1504 and was the wife of William Lumnor.
