A large church with W tower, a wide aisleless nave, chancel and N and S transepts. The W and S faces of the base of the tower, the chancel arch and the N and S nave walls and doorways are 12thc.

The W and S faces of the tower have chamfered round-headed windows, built into buttresses. The W window has been heavily repaired with mortar. Another window, round-headed of two plain orders is found in the N wall of the nave. There is also a chamfered (but otherwise plain) arch of four orders to the tower with three orders on the E.

The church, of brown Cotswold type stone, was drastically restored in 1846. (VCH)
