Yr Hen Gapel, forecourt railings, and Minister's house

This is a large, broad-fronted chapel, likely dating to the 18th century, constructed from squared rubble and covered with a slate roof. Around 1870, gabled porches were added to the exterior, along with a central gable, all featuring framed bargeboards and clayware ridge finials. There are two large windows with segmentally arched heads centrally positioned, and three-light timber windows from the late 19th century illuminating the ends of the gallery. The side elevations have two tiers of four-pane sash windows, the lower range with segmental brick arches. To the right of the chapel is the minister’s house, constructed with a pebbledashed exterior, slate roof, and a gable stack. The house has a glazed door and 19th-century six-light sashes on the front, while above are six-paned windows dating to the middle of the 19th century. An open stair on the east end rises to a panelled door leading to the gallery.

The chapel's interior, dating to around 1870, is complete and richly decorated. The rectangular plan features plastered walls and a boarded ceiling in four bays, each bay divided by octagonal timber ribs and central ventilation medallions. A gallery extends around three sides, supported by seven iron columns with reduced Composite capitals. Diagonally boarded draught lobbies surround each entrance, and stair enclosures are located on either side for the gallery stairs. The gallery provides three rows of raked pews, along with a wall bench, and cuts diagonally across the corners. A raised pulpit, symmetrical in design and accessible via steps on each side, features timber arcading over panelling. An area for the Sêt-fawr (members of the church elders) and a bench for elders are enclosed at the front, with an organ built into the centre. The chapel has stained softwood pews set on a raked floor in three banks, with additional pews at the front. Stained glass windows from 1907, depicting "Light of the World" and "The Good Shepherd", are located in the two large windows either side of the pulpit; these were created by A.L. Moore of London.

The chapel also contains several wall monuments, including a white tablet with a crowning urn on slate by Wilkins of London, commemorating Catherine Francis, who died in 1814, with a subsequent addition for Robert Francis. Another monument is a gabled white marble tablet on slate, honoring Samuel Roberts, who died in 1885, John Roberts (died 1884), and Richard Roberts (Gryffydd Rhisiart), who died in 1883, created by Marshall of Shrewsbury. A gabled white tablet on slate, by Spence of Liverpool, commemorates Lewis Rees (died 1800), Richard Tibbot (died 1798), and John Roberts (died 1834). A tablet by Williams of Llanelly recognizes John Williams of Hendre, who died in 1877. Finally, a bronze monument on Carrara marble is dedicated to John William Daniels.
