This little church is situated about 6 miles NW of Oxford in a quiet backwater just off the A44 road. Originally of limestone rubble with ashlar dressings, it retains the original 12thc. structure of chancel, nave and W tower. The third stage of the tower with a saddleback roof was added in the 14thc. The small gable window in the chancel and the window and openings in the lower stages of the tower are probably original. Although the nave and chancel were largely rebuilt in the 19thc., there is an unspoilt Romanesque S doorway with decorated shafts and capitals, and chevron over the arch. The Romanesque chancel arch was dismantled but rebuilt, probably re-using original materials, and it too has decorated shafts.
Extensive restoration and alterations took place in the 19thc. Until 1828 there were narrow single light 12thc. windows at the E end of the chancel and in the S end of the nave at the E end. These were replaced in the Romanesque style, that on the S side being given 15thc. exterior mouldings, and the walls were rebuilt down to below window level. In 1845 the rector dismantled the chancel arch and rebuilt it using the same materials. The 12thc. small gable window at the E end was discovered and opened up at that time (VCH). In 1982 a blocked N doorway was discovered opposite that on the S.
