Description
The Church of St Cattwg is a largely medieval building, constructed from local limestone rubble with Sutton stone and sandstone dressings, and covered by Welsh slate roofs. The church consists of a nave, a south porch, an unbuttressed west tower, a chancel, and a small north vestry.
The nave has a gabled porch, apparently Victorian, centrally placed on the south wall, featuring a pointed archway with a dripmould and square stops, coping, and a cross on the gable. Flanking the porch are paired, square-headed windows of mid 16th century style, each with three lights and a dripmould. A two-light lancet window was inserted on the north wall in 1882 by Prichard, and a wall projection indicates the former location of the rood-loft stair. The east gable is coped with an apex cross.
The chancel features three single lancet windows on the south wall, and a three-light Decorated east window with cusped heads and a sexfoil above, topped with a coped gable and apex cross. The north wall is largely occupied by a lean-to vestry with a two-light window and a Caernarvon arched doorway, both dressed in Bath stone.
The tower, noticeably battered in its lower half, rises in four stages. Its west wall contains a depressed arch-headed doorway, above which is a two-light window. The north and south walls each have a small rectangular window on each stage, and the south wall additionally contains a small stair window. The bell chamber has louvred two-light openings on each face, and the tower is topped with an embattled parapet resting on corbels.
The entrance and tower arches have a hollow chamfer and may date back to the 13th century. The interior largely contains Victorian furnishings, with the exception of a fine 12th century Norman font, the upper parts of the chancel screen dating to the 15th century (representing a probable survival from the original rood screen), and a communion rail from 1934. An interesting, albeit now faded, medieval mural, possibly depicting St. George, is located on the north wall. Significant memorials are present, including an excellent marble monument to Dr. William Towgood near the font. The nave roof, of uncertain origin, appears older than the Victorian period and is an arch-braced collar beam construction with six bays. The chancel roof is Victorian and of a smaller three-bay design. The church is said to contain three bells, one from the 14th century and the others dated 1637 and 1777.
