Eglwys Bresbyteraidd Cymru

Eglwys Bresbyteraidd Cymru is a chapel built in the Beaux Arts style, featuring a roughcast render with smooth rendered dressings and a hipped slate roof topped with two vents. The entrance front faces the street and consists of five bays arranged in a 1-3-1 pattern, with the outer bays having pediments. Fluted capitals adorn the pilasters that support the pediment, which is decorated with dentilled enrichment. The half-round windows below the cornice have strongly moulded keystones. Each outer bay has an advanced porch, also pedimented in a simpler style, with paired panelled doors. The inner bays are arcaded with engaged Tuscan shafts, and the windows above them form a continuous horizontal line, featuring strongly moulded round-arched heads with keystones and 12-pane sashes throughout. A moulded cornice runs above, clasped between the advanced outer bays.

The return elevations each have a five-window range, with a narrower bay towards the entrance front. This bay and the end bay are emphasized by fluted capitals on the pilasters, while the other pilasters are plain but strongly articulated. A continuous impost band of round-arched windows wraps around them, and there is a moulded cornice. The rear elevation is partially obscured by later additions, but a central pedimented projection with coupled pilasters is still visible.

Inside, the doorways in the entrance porches lead to polygonal lobbies formed in the outer angles of the chapel. The floor is gently raked down with angled aisles between banks of pews arranged around the set fawr and pulpit at the centre of the rear wall. The coved ceiling features window embrasures cut into the coving, which is finished with distinctive encrusted plaster-work. A frieze of rosette decoration leads to a boarded panelled ceiling with moulding around inset central panels and a deeper inset central row of three panels, along with two pendant ventilator/light fittings. The boarded dado complements the wood panelled set fawr, which has wrought iron scrollwork backing, fretwork decoration, and turned posts to the pulpit, backed by an aedicule with inset panelling.
