three stages are of coursed ironstone with limestone ashlar cornerstone dressings; the top late 14th-century stage is entirely ashlar, as are the battlements, pinnacled at each corner, and the crocketed recessed octagonal spire. The spire is topped by a finial with weathercock, and at its lower part contains a single run of twin-light pointed arch lucarnes, these on each alternate face, each set in gables with a globed device attached above. The tower is drained by one gargoyle centrally placed on each side below the battlements. Each corner is buttressed to the full height of the tower on the west side and from the nave and aisles upwards on the east. Clasping buttresses run to the top of the third (belfry) stage, and angled buttresses run over the fourth. The tower first stage contains one large pointed arch Decorated window, this on the west side, with no hood mould and plain glazed with twin lights (lancets) leading to trefoil heads. The central mullion runs to an oval rosette with quatrefoil insets, characteristic of c.1250-1310 Geometrical tracery. The second stage contains small and narrow single light windows on all but the east side. The third stage lies above the line of the nave, with the achievement of a single window on all sides. Each of these windows are of similar pattern to the bottom stage west window, but smaller, with transom—separating horizontal bar—and with an attached hood mould. The fourth stage windows are elongated versions of the third stage, but with added label stops at the spring of the hood mould. The tower sits on a simple moulded socle (plinth) topped by a cill band—angled projection that allows water to flow from a building face—which continues around the whole church apart from the south aisle. The nave is defined only by the clerestory above the abutted north and south aisle roofs, and a gable surmounted by a cross running from the clerestory's coped parapet as it meets the east chancel. The clerestory contains vertically segmented clear glazed twin-light windows, four each north and south, all containing panel tracery—a Perpendicular style of upright straight openings above lower lights—within flattened arches with hood moulds with label stops. Attached to the nave are the north and south aisles. The early 15th-century north aisle is of string-coursed ashlar, buttressed, with four windows of same appearance and style—rectilinear with inset three lights of simple round head,
