Capel y Graig and attached railings and gates

Capel y Graig is a chapel built from rubble stone and topped with a slate hipped roof. The long-wall facade features arched windows and doors, including two central windows, two outer doors, and two upper outer gallery lights, all framed with cement surrounds and set on a cement plinth. The glazing dates from 1928 and includes marginal bars and radiating-bar heads, along with later 20th-century double six-panel doors that have radiating bar fanlights. A plaque is located at the center of the facade. The side walls are rendered and windowless, while the rear wall has two small six-pane sashes for the gallery and two twelve-pane sashes below, which are not aligned.

In front, the left forecourt is enclosed by low Glogue stone walls topped with slate coping and spearhead iron railings, featuring larger stanchions with cast-iron finials. There are two slate monolith gate piers with pointed tops and wrought iron gates adorned with scroll spearheads and lower dog-bars. The top rail of the gates is ramped down to the middle.

The interior was refitted in 1928, while the three-sided gallery is older, with its column supports replaced by girders during the refitting. The gallery front is made of painted grained wood and features a cornice beneath vertical panels with intermittent panelled pilasters and curved angles. A square panel in the center holds a clock. The gallery has raked pews, while the main pews are made of pitch pine with panelled backs and shaped bench-ends, arranged in three blocks. A curving great seat and two inward-facing pews back onto internal porches surrounding the pulpit platform. The pulpit, dating from 1875, has large turned newels and ball finials on the balustraded steps on each side, with matching concave curved balustrades that extend out to the pulpit front, which features two panels of figured wood and a bookrest above. The base of the platform includes an attached center bench and recessed benches in the incurved flanks. Behind the pulpit is a timber arched aedicule. The ceiling is diagonally boarded in four main panels, with a large roundel at the center and a narrow border, the roundel filled with a lattice pattern of timber strips.
