Description

The Church of St Mary is a 19th-century building featuring a nave with a west bellcote and a south porch, along with a chancel that has a north vestry. It is built from local reddish limestone random rubble, with free (Bath) stone dressings and stone slate roofs. The nave includes two windows on each wall and corner buttresses with offsets. The south wall has a central porch with a pointed arch doorway and a steeply pitched gable above that contains a trefoil. The entrance features a flattened arch doorway that may be medieval, likely reused. Inside the porch, there is a neatly inscribed stone that once served as a stile into the churchyard, reading: "Who Ever hear on Sonday, Will Practis Playing at Ball, it May Be before Monday, The Devil Will Have you All." Flanking the porch are two-light windows with chamfered frames and decorated heads. The north wall has a single light window and a two-light window with trefoil heads. The roof is steeply pitched with coped gables. The west wall features a pointed arch window of two lights and a gabled bellcote above, which holds a single bell in a trefoil-headed opening, topped by another trefoil and an apex cross.

The chancel has a slightly lower roofline than the nave. Its south wall includes a doorway with a Caernarvon head and another two-light window similar to those in the nave. The north wall has a projecting vestry with a triple lancet. The east wall of the chancel features a three-light window with cusping, which shows signs of having been inserted, indicating that this wall may not have been entirely rebuilt. It has a coped gable with an apex cross.

The interior was not inspected during the resurvey but is believed to be entirely Victorian with standard furnishings, including a stilted chancel arch.
