Church of St Mary

The barn-like interior, with its W gallery and minimal chancel, was designed to maximise capacity, and was built for an emphasis on preaching rather than ritual. The nave has a flat plaster ceiling divided into 8 bays by thin beams on corbels. The nave and N, S and W nave walls and chancel all have string courses at sill level that terminate with head stops. The round moulded chancel arch of 2 orders, the outer order on scalloped capitals. It is flanked by similar smaller arches (blocked to R side, leading to vestry on the L side). The chancel has a string course at impost level carried over the windows as hood moulds.

The W gallery is carried on 2 polygonal wooden posts and has a panelled front. The font is typical Norman style with round bowl and stem, and 4 detached round shafts with scalloped capitals. The added polygonal pulpit has open Gothic panels. The continuous chancel screen is late C19. It has a panelled dado, 11 lights with open Gothic tracery, the central light wider and forming the doorway, a cornice with vine trail, and brattishing intersected by polygonal finials. The communion rail is brass and is carried in twisted iron uprights with scroll brackets.

Attached to the nave S wall are 2 classical alabaster wall tablets by Jacob Morgan of Pontypridd. These commemorate Ann Davis (d.1852), with a relief of a woman in mourning, and Elizabeth Davis (d.1860), with a relief of a woman on her deathbed being taken up to heaven.

In the porch, beneath the tower, is a cantilevered stone stair to the gallery and belfry. A memorial tablet to the 1914-18 war is signed by 'Morgan'.

A simple Italian Romanesque style parish church, comprising nave with NW tower, shallow chancel and added NE vestry. Rubble stone walls (intended for render) have hammer-dressed quoins to the pilasters, a coursed rock-faced plinth, and lighter freestone dressings to the windows. The nave is 8 narrow bays with pilasters strips. Tall round-headed windows have thin attached shafts and sill band. The window in the L-hand bay is shorter as it has a round-headed doorway beneath it with chevron moulding in low relief, which has a replaced door. The nave N wall is similar to the S. The 3-bay W wall has a wider central bay beneath a gable, which has a round clock face in a freestone surround. The centre bay has a pair of rounded-headed windows similar to the S side, with a similar single window to the R-hand bay. To the L-hand bay is the projecting 4-stage tower.

The tower has a round-headed W doorway with one order of shafts, scalloped capitals and an arch incorporating chevron and roll mouldings. The hood mould has scalloped stops. The N side has a single round-headed window in the lower stage. The middle stages are recessed between angle pilasters. A blind narrow light is in the second stage. In the third stage is a 5-bay arcade of narrow round-headed arches, the middle 3 of which are glazed. The arcade continues around the remaining faces. Two tiers of offsets are above the third stage. The bell stage is therefore narrower. It has 2 tall round-headed belfry openings, the upper parts with louvres. The angles have thin attached shafts.

The 3-bay E wall has round-headed windows R and L, and a blocked round-headed doorway lower L. The chancel is a low round apse to the central bay, which has 3 tall narrow round-headed windows (partly obscured by the projecting vestry on the N side) and is rendered between pilaster strips and sill band. The pediment has a thin cornice similar to the W wall.

The NW vestry has a lintelled doorway to the W side below an oculus and with foundation tablet, while the E gable end has 3 round-headed windows.
