diamond-pattern leaded clear glazing, and flattened hood moulds. Three windows are placed on the north wall, the fourth serves as the aisle west window. Between the two north wall western windows is a simply moulded and slightly pointed door opening with hood mould and label stops, and a carved finial above. Within is a face-hinged oak door. The north aisle parapet is deeply crenellated to the same style as the tower battlements. Above the windows runs a moulding, defining the roof edge at the base of the parapet, holding two gargoyles which drain the aisle roof. Two double-stepped angle buttresses support the aisle on its north wall, with a third diagonal buttress at the north-west corner. The south aisle shows a plain parapet above coursed ironstone with ashlar edgings reflecting the lower stages of the tower. Three three-light windows, one plain glazed to the west of the porch, two stained to the east, are of same style to those of the north aisle, but with added facetted details between the head arches and the frames. The 1858-rebuilt ashlar south porch, which Pevsner describes as "imitation Early English", is entered though a pointed arch moulded opening supported by three columns, with a hood mould with label stops above. The porch roof parapet is coped and runs into the south aisle parapet, and above the doorway opening rises to a shallow pointed gable surmounted by a cross of Celtic appearance. On the west and east side are flat headed windows with twin lights, clear glazing, and tracery, and hood moulds with personified label stops. Inside the porch the nave door, with its elaborate hinges and handle surrounds, is set within a pointed arch opening surrounded by a multi-facetted moulded arch supported by columns with floriate capitals. The chancel with its side chapels—all c1325-1350 except north chapel early 15th century—are string-coursed: chancel east wall entirely ashlar; south chapel walls ironstone with east wall ashlar above; and north chapel ashlar with ironstone at its east half below a window cill band that continues onto the east wall of chapel and chancel. The chapel parapets are deep crenelated repeats of the tower battlements. At the east wall the parapets follow the angled roof line of both chapels and meet a plain coped gable at the east chancel wall. Four pinnacles define the corners of the chapels and the edge of the chancel gable. The pinnacles,
