Bethesda'r Fro Chapel with attached mounting block

Creamwashed local rubblestone walls with dressed quoins; windows of Dundry or Forest of Dean stone; Welsh slate gabled roof with stack at north-east end. Gabled south-west entrance elevation with two stone steps up to four panel wood door with sloping slate roofed canopy on wood brackets over. Semi-circular tablet above the door, inscribed 'Bethesda'r Fro/1807', but this is on brackets not fixed into the wall and comes presumably from an earlier building. Blank walling to north-west and north-east elevations. South-east elevation lit by three pointed windows with dressed stone voussoirs, each window of 2-lights with Y-shaped tracery with impost blocks and with tooling to the jambs. Small single storey wing (accommodation for the peripatetic Minister) attached to south-west end; slate gabled roof with stack to north-west gable. South-east gable end with a window and a door, both with stone heads. Stone mounting block against north-west gable end comprising a double flight of three stone steps.

Interior retains its box pews with the 'high seat' in the centre window; blocked fireplace at north-east end.
