The church has a small rectangular barrel-vaulted nave (measuring 8.78m x 5.33m internally) with an upper chamber under a steep gabled stone roof. The chancel is lost but the chancel arch, plain, with chamfered imposts, remains. Small gabled windows survive on the N and S of the nave and in the E gable of the upper chamber. There is a round-headed window at the W end of the upper chamber. The only sculptural decoration is found on the W doorway. A collection of loose carved stone including some Romanesque pieces are housed in the church.
