Church of Saint Sadwrn

The Church of Saint Sadwrn is a building of rubble stone construction with slate roofs, dating from the medieval period and largely altered in the 19th century. It consists of a nave and chancel under a single roof, a west bellcote, a south porch, and a short southeast chapel or chancel aisle with a separate roof.

The architecture is characterized by a mix of original and replacement features. Most windows have been replaced with 19th-century flat-headed windows with hoodmoulds in grey limestone, although a small medieval window remains on the north side, featuring red stone jambs. The west end has a cambered-headed door with stone voussoirs, and evidence of a blocked pointed window opening above. The southeast chapel aisle has a flush east wall, a smaller gable, and a window dating from around 1500, flat-headed with a hoodmould, red sandstone ogee heads, and limestone jambs, with a blocked third light revealing the original window size. The south side of the church has several 19th-century two-light windows and a cambered-headed doorway, leading to a plank door within a Tudor-arched timber surround, with attached strap hinges. Large rubble buttresses are located on the south side.

The porch, possibly late medieval in origin, features a single-chamfered pointed doorway, stone benches, and three oak-pegged collar trusses, likely dating from the 17th or early 18th century. A blocked late medieval two-light window survives near the north nave window.

Significant alterations occurred in 1883-85, including plastering of the nave walls and stripping of the chancel to expose the underlying rubble stone. The church now has five-sided rafter roofs and a inserted chancel arch constructed from molded Bath stone with corbelled squat columns. The chancel features broad recesses in the south wall, one with a door and steps leading down to the southeast aisle. A low, blocked doorway is found on the north wall of the chancel, with a single pink stone lintel. Late 19th-century stalls with panelled Gothic frontals are also present, along with roundel motifs and squat column shafts on the bench ends. The south aisle has been divided into two rooms with a concrete floor and boarded roof. Floor slabs commemorate T Cornwallis of Abermarlais (died 1699) and D Thomas of Troedyrhiw (died 1853). The west room retains four beams, three of which are chamfered, one with an ovolo molding. The church houses a timber pulpit on a squat octagonal shaft, and a plain octagonal font.
