Interior
The nave is of 2 bays, the roof supported by three medieval heavy arch-braced trusses of almost cruck-like form tapering up from within the walls and carrying 2 tiers of purlins with windbraces. The walls are plastered and have a panelled dado. Wood block floor. The form of the early trusses is repeated in both transepts and chancel, the latter entered by a low springing wide limestone arch. The rebuilt chancel is lined with brick, now whitewashed, and has open ashlared eaves. It is raised four steps above the crossing and ends with the quarry tiled sanctuary. Serving table set in a wall niche on the S side.
Fittings: chancel screen, C15 but restored in the C19. It has traceried openings either side of the wider central arch, and a moulded central rail with raised fleurons; font, by the W door, C19 limestone and octagonal with a panelled spire cover; pulpit: late C18 or early C19, panelled, square with angled corners, the panels engraved with a star motif; lectern: 1901, brass eagle; pews: a full and impressive set of early C19 low box pews with spindle galleries around the tops. At the W end a wall cupboard occupies the recess of the blocked S door, and has, at its side, a chunky medieval corbelled stoup. The vestry retains sections of panelling with various inscriptions. Two banks of C19 choir stalls, 5 each side of the chancel, and oil lamp brackets above.
