the nave is adjoined by aisles on the north and south sides, the one to the south continuing across the south face of the west tower. the chancel has chapels on the north and south side. the tower was built in the 13th or early 14th century and comprises three stone-built stages with a fourth stage, containing the belfry added later in white painted weatherboarding with a pyramidal roof. louvred openings occupy the centre of each side of the belfry. small rectangular or pointed lancet windows pierce the stonework on each external face of the lower stages, except the south face which abuts the south aisle. a square stair turret with window slits adjoins the north-west corner of the tower.
