EXTERIOR: In the south wall of the nave is a blocked C12 doorway.
This has a roll-moulded round-headed arch with colonnettes with cable mouldings and carved capitals and a tympanum decorated with hatched triangles.
The porch has been restored and rebuilt on taller north and south side walls but the surviving flamboyant heads to the timber traceried sides appear to be original, as does the timber arched outer doorway with carved spandrels.
INTERIOR: small C12 style round-headed chancel arch of two orders.
On the north wall of the chancel there is a feature considered to be a C14 Easter sepulchre.
The circa C12 font has a large plain bowl with a square section moulding above the later stem.
The stem on this font is Victorian, but the bowl and base is Norman.
Encaustic tiles to the chancel.
Jacobean pulpit and reader's desk in one with carved decoration below the cornice and tiers of panelling.
