Blaenfos Baptist Chapel

Blaenfos Baptist Chapel is an 1856 Baptist chapel featuring unpainted roughcast with stucco details. The building has a two-storey gable front with a triangular recess in the gable that displays the name "Capel y Bedyddwyr Blaenffos." There are two first-floor arched windows with small-paned glazing and two ground-floor 20th-century windows designed to imitate 16-pane sashes. The chapel has a raised plinth and double doors set in a raised surround, featuring a cambered head, keystone, and some fluting. Above the door, there is a plaque that reads, "Adeiladwyd y ty cyntaf yn y flwyddyn 1765, yn ail yn 1807 a'r Addoldy hwn yn 1856."

The sides of the chapel are two-storey with two windows, which include 16-pane sashes below and arched sashes with radiating bar heads above. At the rear, there are two long arched windows with plastic glazing. Inside, the chapel has a flat ceiling that may have later 19th-century boarding and a coved border. There is a three-sided gallery supported by three marbled wood columns with high bases. The painted grained gallery front has a cornice that breaks forward over the columns, and the panelling is divided by piers. The pews are grained and square, with the side ones featuring doors.

The rear vestibule includes a coloured-glass traceried centre window and two five-panel doors. The pulpit is notable for its thick ball-finial newels and steps leading up to a square pulpit with turned angle shafts and an integral panelled seat. An early 20th-century organ by G. Osmond of Taunton is located behind the pulpit.
