The church has chancel, nave with N and S aisles and arcades of three bays and S porch, and W tower. The tower appears to be early 13thc. as a simple, blocked pointed window in the S wall may suggest. There is also a blocked pointed window in the S wall of the S arcade. There is a blocked doorway with a depressed arch in the N wall of the N aisle and the tower arch is also depressed. The church seems mainly Perp. 12thc. sculpture is found on a reset doorway used as the churchyard entrance, to the S of the church. The fabric of the church is mainly granite, in regular blocks although the N wall has shale interspersed with the granite. The tower is shale with granite quoins.
