The chancel arch is small and two-centred, resting upon large Norman cushion capitals. Two small squints flank the arch. A large outer arch projects slightly from the chancel wall above the smaller arch. C19 scissor-truss roof to chancel and nave. Decorative C19 reredos, with three stone cusped and crocketted ogee arches supported on dark green marble (?) pillars, possibly incorporating earlier stonework. Norman pillar piscina to the SE corner of the chancel. A C19 Neo-classical memorial to the Jones family of Llandow is set into the S wall of the chancel, showing a classical white marble urn draped in black. The pulpit and pews date from the late C19 restoration. The Norman font is located immediately to the W of the S door and has a bold-roll moulding to the top. Narrow two-centred arch into tower.

Staged buttress to each corner of the E elevation of the chancel. Stone cross to coped gable. S elevation of the chancel has a central, narrow round-headed priest''s door. To the right of this is a monument set high up on the wall, close to the C19 buttress. The monument is inscribed in Latin "Hancorne, rector of Llandow A.M. from the year 1681, restored this chancel in the year 1712". The chancel is lit on the S side by a single, early lancet at the E end and a two-light window with square label. The nave has a central gabled porch with C19, two-centred outer arch, with a round-headed Norman inner doorway. On the E side of the porch are three upstanding C18 tombstones.

There is a single, square-headed stairlight to the S face. N elevation of the chancel lit by a single cusped, ogee window with trefoils to the spandrels under a flat, timber lintel.
