Church of St Mary

The Church of St Mary is a largely medieval building, with Victorian additions and repairs, constructed of fairly random limestone rubble with dressed stone quoins, and covered by Welsh slate roofs. The church consists of a nave, chancel, south porch, and an unbuttressed west tower.

The south wall of the nave features a centrally placed porch with a steep, coped gable and cross. The porch has a pointed arch for both the external and internal doorways, and a fine 18th-century door with raised-and-fielded panels. The internal doorway has two orders of chamfering, with the outer order featuring broach stops. The porch roof has decorated, panelled wallplates. To the left of the porch is a two-light Victorian window with trefoiled lights and a quatrefoil between. To the right is a Perpendicular window with hollow chamfered mullions. The east gable has a coped gable and an apex cross. Alterations to the roofline are visible against the tower, whereas to the right it aligns nearly with the chancel roof. The chancel south wall has two two-light pointed arch windows with Perpendicular tracery, possibly fitted into an earlier frame. The east gable contains a large three-light Perpendicular window, topped with a coped gable and cross. The north wall of the chancel is blind. The nave has a slight projection for the rood stair, containing a small rectangular window with a dripmould. The nave also features a large four-light Perpendicular window constructed of Bath stone with a king mullion, and a smaller two-light Bath stone window with cusping.

The west tower is three-stage, featuring a plinth and a substantial batter. A stair is located in the south-east corner. The west doorway has a pointed arch and a modern door, above which is a three-light Perpendicular window. A plain opening is visible on the south face, and two-light openings are present on each face of the bell-chamber. The tower is finished with a battlemented parapet and was repaired in 1893.

Inside, the walls are plastered and painted, with the exception of the dressed stones. The plain, pointed chancel arch with chamfered imposts represents the earliest feature. A fine, tall tower arch with double wave moulding dates to the 13th century, along with the tub font. The nave has a waggon roof, divided into four panels with light timber divisions, while the chancel has a Victorian boarded roof of 1860. A late 17th- or early 18th-century communion rail with turned balusters is also present. There are early 20th-century oak benches and oak and brass candelabra. A late Jacobean, octagonal pulpit is likely contemporary with the altar rail. The church contains several good 18th-century wall monuments, particularly those dedicated to the Jones family of Fonmon Castle.
