Ainon Welsh Baptist Chapel

The Ainon Welsh Baptist Chapel, dating from 1886, is constructed of rockfaced sandstone with ashlar dressings to the front, rendered and scored walls to the sides, and a rear wing of rubble sandstone. The main building has an artificial slate roof, while the rear wing has Welsh slate. The front facade is gabled, with three bays. The gallery level features two round headed sash windows with two panes of margin glazing, ashlar surrounds, keystones, and protruding sills, alongside a central tripartite window with similar glazing where the centre light is double and contains a decorative roundel. Above the windows is a pediment with a bracketed cornice, an inscription panel reading 'Ainon Addoldy y Bedyddwyr Adeiladwyd AD 1886' (Ainon, the Church of the Baptists, Built AD 1886), and a blind round headed arch at the apex. The ground floor has a central round arched doorway with twelve-panelled double doors and an overlight of circular tracery, again with decoratively dressed ashlar voussoirs, a keystone, and quoins, flanked by two segmental arched windows with matching surrounds. Inscribed dedication stones are located below each window. The building has moulded ashlar quoins, a string course, and a rock faced plinth. A shallow tiled forecourt extends to the front, surmounted by iron railings with central double gates, brick end piers, and side gates. A rendered rubble wall borders the right side.

The left side elevation has four bays, featuring fixed margin glazed windows at gallery level with keystones and painted brick surrounds, a dividing string course, and segmental arched six-pane margin glazed windows on the ground floor with keystones. There are also two tiers of ventilation grilles. The rear wing, slightly set back, includes a separate segmental arched doorway with a replaced door and six-pane overlight, and two segmental headed margin glazed sash windows, all with rockfaced surrounds. Stone steps to the rear door are bordered by a part angled rock-faced stone wall with three piers capped with pyramids and incorporating railings.

Inside, a three-sided raked gallery has decorative, vertically bowed cast iron fronts, a wooden rail and coving, and is supported by seven cast iron piers. There is a two-tiered platform for the set fawr (choir) and pulpit, with flanking steps all featuring cast iron railed bowed fronts and metal lamp brackets. A large blind round headed arch is set into the wall behind. The ground floor has pews with doors, some set diagonally, with scribed walls. The ceiling is panelled and boarded, with ventilators, a large rose, and two smaller roses, alongside moulded plaster cornices. A vestibule provides access and contains a part coloured glass double light fitting.
