The church comprises chancel, nave and S porch with a wooden bell turret over the W end of the nave. The nave is 12thc., the chancel (originally 12thc.) was rebuilt in the 13thc. The brick porch is modern. The nave has a 12thc. S doorway, plain apart from a chamfered impost, and one of the original small, splayed 12thc. windows (now blocked) survives in the N wall of the nave. Romanesque sculpture is found on the exterior of the N doorway, and on the chancel arch. There are also some moulded fragments at the W end of the nave. The nave and chancel walls are of coursed rubble masonry with ashlar quoins, the W and S wall of the nave and the E wall of the chancel are rendered. VCH records that the church was restored in 1888, the chancel being shortened at this time.

The advowson was held with the manor of Little Hormead. It was in the hands of Count Eustace of Bologne at the time of DS. Occasionally, throughout its history it was held by individuals who did not hold the manor. by 1730 it had been bought by St John's College Cambridge.

The church is known for its 12thc. ironwork which is now displayed on the interior of the N door.

VCH dates the nave to 1140-1150.
