Blaenavon Evangelical Church (Moriah Chapel)

Blaenavon Evangelical Church, also known as Moriah Chapel, features a classical three-bay gable facade that is rendered with stone dressings and topped with a slate roof. The facade is divided by pilasters at both the ground floor and the gallery level. All openings are adorned with semi-circular, moulded stone arches and chamfered jambs, while the windows have angled stone sills. A flight of steps leads to the ground floor entrance, which consists of three narrow doorways. Each doorway has panelled, glass and wooden double doors that are set back, topped with a semi-circular fanlight featuring stained glass. On either side of the entrance, there are stained glass windows framed by pilaster architraves, with their sills supported by pairs of console brackets. A string course connects the keystones of the doors and windows, forming the base of the entablature that has a dentilated cornice.

The first floor showcases a tripartite central window with a pedimented keystone and pilaster jambs, flanked by two additional windows that also feature pilaster jambs and pedimented keystones. Above these windows is a panel with curvilinear decoration and the date 1888 in relief, along with the remains of the original name of the chapel. An entablature above this marks the start of the roof pitch, which is complemented by a simple wooden barge board under the verges supported by four brackets, and a semi-circular opening at the apex.

The return facade consists of five bays across two storeys, rendered with a dressed stone plinth. The openings have the outline of keystones and arches traced into the render. The ground floor includes one door and five windows, each with a cambered arch and stone sills supported by pairs of brackets. The gallery floor features five semi-circular windows with angled stone sills.

At the rear, there is an added school-room constructed of rubble stone, with dressed stone quoins and a slate roof. Its openings have cambered arches made of brick, and the windows have angled stone sills.

Inside, the chapel retains many original features, although it has lost its pews. Iron columns with gold-painted spiral decoration support the gallery, which has pierced ironwork balustrades. Access to the gallery is provided by twin staircases from the entrance vestibule, and the pulpit remains in place.
