The oldest visible parts of the present Church of England parish church of St Mary the Virgin include the early 12th-century Norman arches supporting the central bell tower, and a tympanum of the same date that is now over the vestry door. Beneath the floor of the chancel are the foundations of a former apse that also was built early in the 12th century. About 1250 the nave was rebuilt and north and south aisles were added, each linked with the nave by arcades of three bays. The transeptal chapel of Our Lady on the south side of the tower may be of the same date, and the apse was replaced with a rectangular chancel late in the 13th century.

The west window of the nave dates from the 14th century, as do two windows flanking a blocked 13th-century doorway in the north aisle. The east window of the chancel, west doorway of the nave and south doorway of the south aisle are also 14th century. In the 15th century a clerestory was added to the nave and a porch was added to the south door.The Lady Chapel was also rebuilt in the 15th century, and other late mediaeval additions include the Perpendicular Gothic windows of the south aisle and another Perpendicular Gothic window in the north aisle.
