Capel-y-dolau C. M. Chapel (also known as Capel-y-ddôl).

A chapel entered through the long side, with an extension at right containing vestry and store-room. Rough-rendered with doors and windows outlined in smooth render; smooth render also used as a sill-level band, a plinth, and to mark the corners of the walls. Slate roofs with tile ridges. The front elevation contains a large central window with transom and two mullions. Two wide doorways and two small flanking windows. All windows divided into small panes; all openings with pointed heads containing interlaced glazing bars. Plain double doors.

A plain interior entered by symmetrical doors; gallery on three sides and pulpit between the doors. The gallery is carried on five plain cast-iron columns each of which has a little motif of the Prince of Wales' feathers and a projecting eyelet for a rushlight. The gallery is reached by a single staircase at the right. Four rows of strongly-raked pine pews facing the pulpit, two rows each side, set fawr raised one step; two rows of pews in the gallery. The pews throughout including the gallery and the set fawr are in painted pine, in similar plain detailing, with panelled fronts and seat backs. The downstairs pews have doors. Gallery front and set fawr both curved at the corners. Central gallery clock. Pulpit front with two large curved-headed panels, breaking forward; newels and balustrade each side. The newels are square, carved with a cross motif, chamfered, and carry knobs. Two have tall finials. Panelled base and symmetrical flights of five steps.
