Description
The Church of St David is a building of brown rubble stone with a slate roof, rebuilt in the 20th century. It contains a long, undivided nave and chancel, a north porch, and a small bellcote. A broad, gabled wooden porch with bargeboards stands on the north side, featuring a pointed, cusped entry with pierced cinquefoil roundels on one side and three quatrefoils on the other. A pointed, chamfered stone doorway with a 19th-century door is present. The 19th-century windows are plain, cusped lancets. A grey stone, trefoil-headed medieval single window, heavily restored, is located to the left of other 19th-century windows, including a two-light, a single light, and a three-light pointed window with a hoodmould and purple stone voussoirs at the east end. The east wall stonework is generally 19th-century. Plaques on the east wall commemorate Thomas Williams of Cwmcamlais Fawr (died 1807), John Williams (died 1794), Margaret Williams of Cwmcamlais Fawr (died 1816), and Alice Walters (died 1817). On the south side, from the right, are a restored medieval two-light window, a blocked late medieval or 16th-century doorway with stopped chamfers to the jambs and a rounded head, a straight joint to the nave, a three-light 19th-century window mirroring the next, and a flat-headed window with three cusped arched lights, potentially of the 16th century. A two-light 19th-century window with a cinquefoil roundel in the head and a hoodmould is found at the west end.
Inside, the walls are plastered, and the roof is a collared scissor-rafter structure. Segmental window reveals are present. A corner fireplace is located in the southwest corner vestry. There is one step to the chancel and a further step to the sanctuary with altar rails. The sanctuary floor is tiled, with one step leading to the altar. The south chancel window sill forms a dropped seat. Fittings include a circular, medieval, retooled font with a chamfered base, a pine vestry screen with arched, cusped openings and a half-glazed door, pine pews with cusped end panels, pine stalls with open front kneelers, and a reading desk with a pierced front. A pulpit stands on an ashlar, chamfered base with a three-sided timber top featuring pointed blind tracery, supported by simple wood rails and braces. An important Early Christian incised stone is located to the left of the north doorway - a tall, narrow stone bearing Ogham incisions 'Cunacennaviilvveto' and Latin script 'Cunocennifilivs Cunogeni hic iacit', along with an incised Latin cross with a circled head. A memorial plaque to the Walters family, dated 1887 and made by Morris & Mainwaring of Swansea, is also present.
