Church of St Cattwg

The Church of St Cattwg is a largely late-Perpendicular church, dating to the 15th century. It is constructed with local rubble and has modern concrete-tile roofs. The church’s plan consists of a west tower with two parallel chambers forming a double-nave and chancel; the nave and north aisle are of roughly the same width, with the eastern part stepped down, the north chancel now serving as the organ chamber. The architecture is characterised by ogee tracery.

The church is dominated by a massive, three-stage tower constructed in narrow blocks of red sandstone, featuring quoins, band courses, and a crenellated parapet. A hexagonal stair turret rises above the north-east corner, with small vertical lights. A large, three-light window is located at the west end, set under a relieving arch, and a blocking indicates that it replaced an earlier window. The top stage has square-headed, splayed, two-light louvre openings, with small vertical lights and sandstone dressings below to the south, west, and east. Similar lights are found on the middle stage to the west and south. A late-20th-century lean-to vestry projects from the north side, with a gabled entrance to the west.

The main south porch has a fine, ogee-arched entrance of Bath stone, featuring crocketed enrichment and a four-centred arched inner doorway. The nave has stepped buttresses and two three-light windows to the east of the porch. The chancel has a further gabled porch for the priest's door, with a simply pointed arched entrance, flanked by fine three-light 16th-century windows, similar to those on the north side. The gabled east end has diagonal buttresses and three-light panel-traceried windows; a crucifix finial is missing from the north gable.

On the north side of the church, the upper courses of the north aisle have been rebuilt, featuring two three-light windows, the eastern one similar to those at the east end and the western one similar to those on the south side of the nave. A raised stone platform with a segmental arch is near ground level.

Inside, a continuous 14th-century two-order arcade with three bays to the nave and two bays to the chancel has contemporary chancel arches, with octagonal piers bearing broach stops. A three-order tower arch is present. The nave has panelled wagon roofs, while the chancel has arched-braced collar trusses with trefoil decoration. A blocked doorway in the west wall, just north of the stair vice, indicates there was formerly a gallery at the west end.

The font, pulpit, pews, organ, and reredos date to the 19th-century restoration. There are eight windows with stained glass, all dating to the 19th century and mostly serving as memorials. The north nave window is by Clayton and Bell and depicts the crucifixion, commemorating Sir Joseph Bailey of Glanusk Park (d. 1858). The east window shows the resurrection and is dedicated by Mary Anne Bailey in memory of her child, Bertha. The tower and vestry contain a series of fine 18th-century Rococo memorials with raised and painted borders, mainly depicting floral designs, by the Brute family of Llanbedr, dedicated to the prominent families of the area, including the Morgans of Dan y Parc.
