A single-vessel church with no architectural division between nave and chancel, but with a wide span. Assertive W tower with big Romanesque strip-buttresses on the corners, of three stories, with Romanesque round-headed windows in the top two stages, and two circular windows at the top of third stage. No sculpture on the tower except roll-mouldings between the stories and around the windows (the E face of the tower, and the whole parapet is of brick, with an attractively cogged lower frieze). Two inscriptions help date the fabric of the building and are likely also Romanesque in themselves. The font is also of the 12thc, but heavily mutilated.

The two inscriptions are of some use for dating the church building. The lord of the manor in 1066 were the monks of Winchester, but by 1086 it was Hugh of Port. His descendant Adam of Port held the manor from 1171 to his death in 1215, placing at least the tower and the walls of the nave in the last quarter of the 12thc. The mention of its founding by St Wilfrid (633-709) implies that there was a church on this site for some time when Adam of Port renovated it. The rectory was assessed at £21, 6s, 8d in 1291. The medieval dedication of the church is not recorded.

The church is in the private (but with a right of way to the church for for pedestrians) grounds of a now-demolished country house, a descendant of the now ruined hall just a short distance E of the building. This hall was a building of some ambition, built mostly it would seem in the 13thc, with extremely high columns that probably supported a timber ceiling. It demonstrates the close links the church must have had with the lord of the manor.
