The church dates to the 11th century. It is one of the smallest recorded in Taylor & Taylor’s Anglo-Saxon Architecture, and exhibits Saxon features in the proportions, the thinness of the walls, a splayed window in the south chancel wall, long-and-short work quoins with large shaped stones, and some herringbone work in the stone rubble masonry of the walls. It consists of a nave and chancel which show these signs of construction in the Anglo-Saxon era, with a later west porch and bell turret.
