Church of St Michael and All Angels, Llangynwyd with Maesteg, including enclosing graveyard wall.

The Church of St Michael and All Angels in Llangynwyd with Maesteg, along with its enclosing graveyard wall, is built from pick-dressed mountain stone, featuring greenish Bridgend stone dressings and slate roofs. The church has an aisled nave with six bays, a short chancel with side chapels, and a tower located on the north side of the chancel. The broad, plain west front includes a central moulded doorway and arches between buttresses, topped by five lancet windows. In the gable, there is a statue of St Michael slaying the Dragon within a mandorla. The nave features paired lancets between gabled buttresses and cinquefoiled round lights in the clerestoreys, which are situated between pilasters. The three-stage tower, completed in 1958, has a crenellated parapet, louvred bell openings, and an octagonal stair tower in the northeast corner that rises above the parapet. The east window of the chancel consists of three stepped lancets, and the tower is faced with stone reclaimed from the Llynfi blast furnaces. The graveyard is enclosed by a low stone wall topped with bold cast iron railings between stone piers.

Inside, the church has a plain interior designed in a Decorated Gothic style. The broad nave features passage side aisles behind the arcades of six bays, with an open roof supported by alternate hammer beam trusses. The moulded tripartite chancel arch has lower side arches, and the square chancel, raised over three steps, contains a single sanctuary arch. The sanctuary walls are painted and stencilled. There is an organ chamber on the north side with a vestry behind it, which includes a stair leading to the crypt. The windows have rere-arches on colonnettes, and the nave floor is flagged. At the west end, a plain tub font is positioned over an unusual immersion baptismal font.

Furnishings include a pulpit on a pedestal, accessible from the chancel, which is octagonal and inlaid with pink marble, featuring colonnettes at the angles. The altar and reredos, made of oak and enhanced with gilding, extend the full width of the sanctuary and date from 1949. The pews are made of pine and include umbrella stands. The glass in the chancel's east and side windows is by R J Newbery, created around 1920 in a Dureresque style, while the north window in the nave is by J Petts, completed in 1985.
