The north aisle was added in the 14th century. The elegant three-bay arcade has shafts which are polygonal to the north and south, and semi-circular to the east and west. The nave was given a hammerbeam roof in the 15th century, which was replaced in Victorian times. A single truss with richly carved spandrels and moulded hammerbeams was retained. The plain, pointed chancel arch is 13th century.
