This medieval church has later features and a 19th century north aisle. The font is probably 12th century in date. A window in the chancel contains 15th century stained glass. A 17th century wall memorial and a coffin slab were originally at All Saints' Church, Oxwick (NHER 7127), but were brought to St Mary's after All Saints' was disused. Possible prehistoric pottery and medieval sherds have been found in the churchyard.
