 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.
