Description
Capel Ainon is a rectangular, single-storey chapel built in the 19th century, designed in a vernacular Georgian style. It features squared, rough-dressed stone blocks beneath a wide slate roof with oversailing eaves and verges. The symmetrical facade includes a central pair of 12-pane, unhorned sash windows, which flank a square inset slate plaque that reads: 'Ainon Addoldy Bedyddwyr 1840 Baptist Chapel.' There are outer entrances on the left and right, each with boarded doors set in pegged and moulded frames. The rear of the chapel has three evenly spaced sash windows, similar to the front, with applied horns and rough slate sills. The gable end displays ashlar joints scratched onto slobbered mortar.
Inside, the chapel remains largely unaltered and features a plain interior. There are boarded inner wind porches with wooden hat hooks on both sides. The flat plaster ceiling is supported by two lateral plastered beams. The seating consists of three rows of raked box pews at the back and front, along with three rows of plain, open-backed pews at the front, all made of pine joinery. The central square panelled pulpit has canted sides and a moulded cornice, with steps leading up that include a wooden rail, columnar newel, and stick balusters. The pulpit also features a plain four-panelled back with a segmentally-arched top, and to the left of the pulpit are three additional box pews.
