there is evidence for considerable medieval alteration to the fabric: the chancel was extended, and the roofs appear to have been raised.
Above the arch of the south-west window are 2 blocks of reused stone with Norman chevron ornament
3 lancets on north side, 2 C19 insertions, but that in the chancel C13.
3-light east window with C19 memorial glass
The small unbuttressed C15 west tower has a crenellated and stepped parapet with flushwork.
There is no chancel arch, but the junction of nave and chancel is marked by an unusual carved timber decoration in the ceiling with droplets, and a wheel at each end, one with mouchettes, the other with daggers.
C15 octagonal font: alternating Tudor roses and blank shields around the bowl, supported by 4 seated lions round the stem.
