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

Capel-y-dolau C. M. Chapel, also known as Capel-y-ddôl, is a chapel entered through its long side, featuring an extension on the right that contains a vestry and store-room. The building is rough-rendered, with doors and windows outlined in smooth render. Smooth render is also used for a sill-level band, a plinth, and to mark the corners of the walls. The chapel has slate roofs with tile ridges. The front elevation showcases a large central window with a transom and two mullions, flanked by two wide doorways and two small windows. All windows are divided into small panes, and all openings have pointed heads with interlaced glazing bars. The doors are plain double doors.

Inside, the chapel has a plain interior accessed through symmetrical doors. A gallery runs along three sides, with the pulpit situated between the doors. The gallery is supported by five plain cast-iron columns, each featuring a small motif of the Prince of Wales' feathers and a projecting eyelet for a rushlight. Access to the gallery is via a single staircase on the right. There are four rows of strongly-raked pine pews facing the pulpit, with two rows on each side, set fawr raised by one step, and two additional rows of pews in the gallery. All pews, including those in the gallery and the set fawr, are made of painted pine, featuring plain detailing with panelled fronts and seat backs. The downstairs pews have doors, and both the gallery front and the set fawr are curved at the corners. A central gallery clock is present, and the pulpit has a front with two large curved-headed panels that break forward. The newels and balustrade on either side of the pulpit are square, carved with a cross motif, chamfered, and topped with knobs, with two newels featuring tall finials. The pulpit also has a panelled base and symmetrical flights of five steps.
