Church of St Cenhedlon (aka Rockfield Church)

The Church of St Cenhedlon, also known as Rockfield Church, is a small building largely dating to the 1858 restoration by diocesan architects Pritchard and Seddon, who rebuilt the nave, north aisle, and chancel in an "effective Decorated" style. The west tower is original, dating to the 14th century, and was also restored at this time. Like churches at Skenfrith and St Maughans, it is characteristic of the Welsh borders, constructed from sandstone rubble. The tower is square, sheer-walled and features a low, two-stage timber-framed belfry that resembles a "dovecote," with the lower stage close-studded and the upper stage having two tiers of small, square, louvred openings and a pyramidal roof. A small loop-light is found on each side of the tower, and a Victorian three-light traceried window is set into the west side.

The church’s sandstone structure incorporates snecked random stonework on the south side of the nave, along with yellow freestone dressings and red tiled roofs. The three-bay nave has a gabled porch in the centre of the south wall, featuring a moulded cusped arch, banded extrados, and a gable coping with an apex cross. To the left of the porch is a two-light window, and to the right a larger three-light window, both incorporating reticulated tracery. The chancel, slightly lower than the nave and of two bays, contains two square-headed windows with reticulated tracery and a large three-light east window with flowing tracery. Both the nave and chancel have gable copings with an apex cross.

The north aisle, which is roofed as a continuous lean-to extension of the nave, contains three simple two-light windows with ogee-headed lights. A lean-to vestry is situated in the angle between the aisle and the chancel. The nave features a three-bay north arcade comprised of cylindrical columns with stiff-leaf capitals, supporting chamfered and moulded two-centred arches, and an arch-braced collar-truss roof with two tiers of wind-braced purlins. The chancel has a wide, depressed two-centred arch, which contains a delicate wrought-iron screen (gifted by the Rev. John Taylor, vicar in 1875). The chancel also has a three-bay roof with arch-braced collar trusses, a panelled reredos behind the altar, and an organ set within an arch on the north side. Located at the east end of the north aisle are the Royal Arms of William III, which were originally used as a noticeboard at Rockfield School and restored to their current position in 1976. A wall monument dedicated to John Allan Rolls, 1st Baron Llangattock (1837-1912), is positioned on the south wall of the nave, to the east of the doorway.
