Capel Rhiwbwys

Capel Rhiwbwys is a large, four-bay chapel with a lateral front, constructed with rendered elevations and a slate roof featuring bracketed eaves. The façade includes two small round-arched windows at the center, each with 22 panes and marginal/intersecting glazing. The outer bays have wide 16-pane hornless sash windows on the first floor, which have cambered heads and are positioned higher than the arched windows due to a heightening in 1871. The windows have painted slate sills. Each outer bay also features a wide doorway with early 20th-century paired half-glazed doors.

There is an inscription on a tablet below the left window that reads: "Capel Rhiwbwys. Adeiladwyd gyntaf yn y flwyddyn 1781. A helaethwyd 1820. Ac a adeiladwyd 1832. Adeiladwyd yr oriel a thowyd Nen 1871." A smaller tablet below notes: "Adnewydd y llawr 1926." The left end has a first-floor 16-pane sash window similar to the front, with a blocked window to the left. The rear has sash windows as described, with three on each storey, and two similar sashes on the right end.

Inside, there is a five-sided gallery added in 1871, featuring a front with long panels and supported by iron columns with foliate caps. The plaster ceiling has a central roundel, with smaller ones on each side and towards the rear. The pulpit, likely from 1871, is three bays wide, with each panel featuring blank oculi and quatrefoils above the center, and timber balustrading above the side panels. There is a consoled bookshelf, short staircases with turned balusters and newels topped with ball finials. Behind the pulpit is a tall panelled backboard with pilasters and a triangular pediment with acroteriae. The broad bullnosed Big Seat has a half-rail of turned balusters, while the lower pews and the panelled inner porches, which include 4-pane windows facing the pulpit filled with leaded and tinted glazing, were added in 1926.
