St Mary's church was originally built as a school and chapel of ease in 1870-1. It stopped acting as a school when the school in nearby Pentredwr was built in 1908, but continued as a church.
It is located at a junction of minor roads at the foot of the escarpment of Mynydd Eglwyseg. Constructed of coursed, rock-faced stone with finer dressings under slate roofs, it consists of a single chamber with polygonal apse, east bellcote, north porch under a catslide roof and lean-to extension on the west gable wall. The church is lit through lancet windows. The last service here was held in 1985. The building is now converted to a dwelling.
