Description

The Former Church of St Mary is constructed from random limestone rubble, featuring Bath stone quoins and dressings. Only the tower remains roofed, covered with stone slates. The nave and chancel are aligned with a south tower that also serves as the porch, and there is a small north vestry. The walls are intact, including the Decorated tracery in the east and west windows. The north wall contains three single light windows with cusped heads, while the south wall has two. The tower is complete, showcasing a flat entrance arch on the outside and a cranked one on the inside, along with a surviving plank door and holy water stoup. The tower is three stages high and square, with quoins; the second stage features a single light opening with a cusped head. The bell stage includes paired louvred openings with cusped heads, a small single light opening in the gable above, and another in the rear gable. The gables are coped with an apex cross at the front. The churchyard is home to a notable collection of 19th-century monuments, three of which are listed.

Inside, there are two small aumbries: one near the door with a cusped head and another by the altar with an arched head and decorated tracery infill.
