Welsh Presbyterian Church

The Welsh Presbyterian Church is a building made of brown brick, some of which is stamped with "W Hancock," featuring freestone dressings and a slate roof. The entrance front on Clwyd Street is wide and gabled, divided into three bays by pinnacled buttresses. In the center, there is a three-bay recessed arcaded porch that serves as a lobby beneath an internal gallery, with doors leading into the chapel on the north and south walls. Above the porch are triple windows with plate tracery and pronounced hood moulds. The outer bays have similar foiled lancet windows, and there are small quatrefoil windows flanking the porch. The north and south elevations each have five bays, separated by pilaster buttresses. The lower storey features two-light plain chamfered mullioned windows, with similar paired windows above set in blind traceried arches. The eaves are topped with a plain parapet.

An additional school room, designed in the same style, has been added as a cross gable to the east. There is a two-storey entrance block set back to the east, which includes a chamfered arched doorway with pierced spandrels, two shouldered mullioned windows on the ground floor of the cross gable, plate traceried windows above, and a small rose window at the apex.

Inside, the coved ceiling is divided into panels by moulded cross-beams supported by ornate brackets, with painted decorations in the angles of the panels. The interior fittings date from the time of the church's extension with the addition of the schoolroom. Open pews are arranged to face a large pulpit within a contemporary set fawr enclosure that includes a deacons’ seat. The horseshoe gallery is supported by cast-iron columns and brackets, featuring raked seating. The gallery's parapet is paneled and continues across the east wall of the set fawr and the organ loft above, showcasing the wood's natural knotting for decorative effect, divided by pilasters and topped with a scalloped cornice. The school rooms form a cross-wing of the chapel to the east, along with the deacon’s room. The upper school room spans the entire width of the building, consisting of five bays with arched braced trusses adorned with scalloped moulding, and ornate open-work plaster ceiling roses that likely serve as ventilators.
