The church consists of a nave measuring 17.5 x 5.6 m internally, with walls of rough uncoursed limestone and ashlar quoins. It is roofless, but the walls are intact and the W wall and doorway restored. A small mortuary was added to the E of the church in 1667. There is a flat-headed door on the N side, a 15thc. door on the S side, and windows at the E end of the N and S walls. The W door incorporates reused Romanesque stones and the E window is Romanesque, both probably built into a later medieval church.
