Capel Pentre Tygwyn

Capel Pentre Tygwyn is a chapel constructed with colourwashed stucco and rubble stone, topped with a slightly hipped slate roof. The eaves feature paired brackets. The lateral facade was altered in the late 19th century, which included the addition of new windows, stucco quoins, and new doors. The facade has arched openings, with two long central windows and two shorter, narrower gallery lights on either side, along with two doors that are slightly set back from the gallery lights. The windows feature later 19th-century tracery with two lights and a roundel, and the central lights are decorated with coloured glass margins. The stone sills are present, and the doors are panelled with crescent-shaped overlights.

Between the windows, there is a memorial to the Rev Edward Jones, who died in 1841, made by D Beynon of Cilycwm. Above this memorial is a plaque that reads 'Sancteiddrwydd i'r Arglwydd Addoldy Pentre-ty-gwyn Yr hwn a adeiladwyd gyntaf yn y flwyddyn 1749 ac a ailadeiladwyd yn 1834'. The end walls are made of rubble stone, and there is a plaque on the eastern end dedicated to Thomas Price, who died in 1839. The rear of the chapel features two arched windows below, with stone voussoirs, and one later 19th-century sash window above in the center.

Inside, the pulpit is located between the windows on the front wall. There is a three-sided gallery supported by three plain iron columns, likely from 1834 or shortly thereafter. The gallery has a deep frieze, cornice, and distinctive front panels with rebated arched heads. The angles are curved, with the angle panels projecting forward, a detail similar to that found at Cefnarthen from 1853. The later 19th-century pitch pine pews are arranged with two aisles, a matching straight great seat, and a large pulpit. The pulpit features steps on each side with ball-finial turned newels and turned balusters, along with a prominent double-curved front with open arcading and column shafts. Behind the pulpit is a plain arched plaster panel, with a rectangular panel above it. There are two lobbies with half-glazed doors, and the two rear arched windows contain stained glass created in 1993 by Janet Hardy, commemorating William Williams. The gallery has open back benches, and the late 19th-century boarded ceiling is divided into nine panels.
