Church of Saint Mary

The Church of Saint Mary is a parish church, dating from the 18th century. It is constructed of rubble stone with an imitation slate roof and red terracotta ridge tiles. The church has a single roof over the nave and chancel, with a lower south transept and a north vestry which is even lower. The gables are coped and shouldered. A thin, plain rubble tower stands at the west end, featuring rough, single bell openings blocked with brick. The tower has a flat parapet with moulded coping stones, creating a battlement-like appearance, and supports a weathervane. It projects slightly from the west end and contains a late 19th-century pointed doorway with a cusped head, and a renewed door with 19th-century hinges. The rest of the church has windows dating from around 1880, constructed of ashlar with cusped lancet designs: two lights to the south side of the nave, a stepped three-light design to the south side of the transept, a single light to the north and south sides of the chancel, and two two-light windows to the north side of the nave. The east window is three-light, pointed, with a hoodmould and simple cusped heads to each light. The north vestry has a Caernarfon arch to the east door and a single light to the north.

Inside, the walls are plastered and the nave has a seven-sided rafter roof. The west wall features the projecting inner side of the tower, with a pointed doorway containing earlier 19th-century double panelled doors. The window reveals in the nave have chamfered pointed heads. A plastered pointed arch leads into the south transept, which has a boarded rafter roof. A Caernarfon-arched doorway leads from the nave to the north vestry. The chancel arch is from the later 19th century, featuring a double-chamfer pointed arch and a hoodmould, the inner arch resting on moulded corbelled capitals. There is one step up to the chancel, which has a tiled floor and a five-sided boarded panelled roof. The east window reveal is segmental-pointed. Another step leads to the sanctuary.

The church contains an octagonal ashlar font dating from the 19th century, featuring an IHS monogramme, a moulded underside, a marble round shaft, and a moulded base. There are also pine pews, a wrought iron and brass altar rail, an oak traceried altar table, and an oak traceried reading desk. There is no pulpit. Memorials include an oval marble plaque to William Lewis and his wife, Jenett, dated 1723 and 1721 respectively, with good lettering; an oval plaque to Henry Bulkeley of Temple Druid (d 1821) with coloured lettering; a rectangular plaque to Rev John Foley (d 1832) with similar lettering; an engraved brass plaque to Edward Cropper and his son Edward, who died in 1900; and a marble plaque to Ida Walters (d 1895). Stained glass depicts the Virgin Mary, Joseph, and John and dates from around 1950. Two incised stones, originally from the churchyard of the ruined church of St Teilo at Llandeilo Llwydiarth, are also present. One reads 'Andagell- iacit fili Cavet-', with a later added incised cross, and the other reads 'Coimagni fili Caveti'.
