Bethesda'r Fro Chapel with attached mounting block

Bethesda'r Fro Chapel, built in 1807, features creamwashed local rubblestone walls with dressed quoins and windows made of Dundry or Forest of Dean stone. The roof is gabled and covered with Welsh slate, with a stack located at the north-east end. The entrance on the south-west elevation has two stone steps leading up to a four-panel wood door, which is sheltered by a sloping slate-roofed canopy supported by wood brackets. Above the door is a semi-circular tablet inscribed with 'Bethesda'r Fro/1807', although this tablet is on brackets and not fixed to the wall, suggesting it may have originated from an earlier building. The north-west and north-east elevations are blank, while the south-east elevation features three pointed windows with dressed stone voussoirs. Each window has two lights with Y-shaped tracery, impost blocks, and tooling on the jambs.

Attached to the south-west end is a small single-storey wing that provides accommodation for the peripatetic Minister. This wing also has a slate gabled roof with a stack on the north-west gable. The south-east gable end includes a window and a door, both topped with stone heads. Additionally, there is a stone mounting block against the north-west gable end, which consists of a double flight of three stone steps.

Inside, the chapel retains its box pews, with the 'high seat' positioned in the centre window, and there is a blocked fireplace at the north-east end.
