Interior
The chancel, vestry, S. transept and porch are all vaulted in stone. The nave and N transept have C19 boarded pine waggon-vault ceilings. The sanctuary is raised by three steps and paved with black memorial slabs. At the N side of the chancel is an arch to a lobby which is now the entrance to the vestry. At the S side is a mortuary chapel, with two roughly-formed four-centred arches of C15 date on a circular pier. The sides of the chancel arch incorporate the splays of the original squints and there are rood corbels. The widening of the chancel arch has been carried to an extreme leaving the arches of the chapels on both sides of the chancel with only minimal abutment. A late C19 pulpit in Early English style stands beneath the N side of the chancel arch.
The S transept has a very high vault contemporary with the tower above, bearing on arches at the W side corbelled out from the wall. A passage squint connects the S transept to the chancel across a corner of the mortuary chapel. The transept also has a deep window recess on the E side where there may have been an altar, and an adjacent aumbry the sill of which is now at floor level. There are openings, 20 cm square, through the full thickness of the E and W walls. Access to the rood is now thought to have been via the lowest stage of what is now the tower staircase and a lost upper floor in the S transept. In the porch there are benches on either side, a water stoup in the corner and a damaged pillar-stoup.
The E window is a memorial to the Rev. G W Birkett, Vicar from 1829 to 1878, by Thomas Ward. It is of three lancets with the centre lancet taller than the others. The W window is of three lights, containing glass seemingly cut down in size. In 1845 the W window was described as 'lately restored'. A brass plaque beneath it commemorates Orlando Harris Williams and Maria, of Ivy Tower, both d. 1849. The glass may be of later date, by Powell of Leeds. A window at the S of the nave commemorates John Leach, the succeeding proprietor of Ivy Tower, d. 1876. Painted windows to the N and S transepts. The other windows are of plain glass. The font is Norman, of cushion type, with three lobes each side, on a circular shaft and square base.
Memorials include that to Griffith Toye, Rector 1577-1601, in the S chapel beside the organ. It is in classical form with a broken pediment. At left of the altar is a plaque to Robert Rudd and Robert Williams (of Ivy Tower), c.1655: Rudd, d.1648, was Rector and also Archdeacon of St David's. Williams was grandson of Bishop Ferrar. A stone at the W side of the mortuary chapel commemorates and displays the arms of John Williams of Ivy Tower, d.1704.
