Church of St Michael and All Angels

The Church of St Michael and All Angels is a small Gothic Revival parish church built in the early Decorated style. It is constructed from coursed and snecked tooled grey and red sandstone, featuring pale ashlar dressings, and has a Welsh slate roof with a corbel table and cruciform finials. The church has a plan that includes a nave with a west bellcote, a south porch, a lower and narrower chancel, and a large northeast vestry with a later hall wing.

The west window is large and consists of four lights with Geometric roundel tracery and face stops to a roll-moulded hood. The bellcote, made of ashlar, has a steeply pitched gabled hood over a double-arched opening that houses a single bell. The south nave features three two-light windows with trefoil tracery and roll moulding. The porch has a steep-pitched gabled roof, battered walls, and a moulded doorway. The chancel includes an east window with three lights and Geometric tracery, along with a small southeast window of paired lights in a square-headed surround. The north nave has a buttress with offsets to eaves level and a similar window; the vestry, which has a single pitched roof, features simple paired lights and a shouldered doorway on the east side.

Inside, the church is rendered with some exposed ashlar dressings. It has a barrel roof with a moulded ridge beam and a boarded ceiling. An unusual north doorway features blind arches and a trefoil design. There is a war memorial to the men of Tongwynlais on the north wall, along with a very plain cylindrical pulpit and font. The wide moulded pointed chancel arch has gilded capitals and head stops, while the finely carved chancel screen is in the Perpendicular style. The chancel is simply panelled, with a sanctuary and choir stalls, and features a boarded ceiling of four bays with painted ribs and a pendant metal cross. The altar and reredos are panelled and incorporate shields, and there are wrought iron altar rails.
