 The church has a cylindrical stone font dating from the 13th century, carved with decorations, particularly an elaborate leaf design and a knotwork pattern. The decoration, however, is incomplete and about one-third of it was left unfinished. Other fittings date on the whole from the late 18th century, as St Cywllog's was refurbished in 1769. They include a triple-decker pulpit combined with a reading desk, with panelling to the front and sides and further panelling at the back of the pulpit. It bears an inscription "M T I I WARDENS 1769". The altar has communion rails on three sides, which are probably of similar date to the pulpit, and seats nearby in the chancel on the north and south walss. There are various 18th-century memorials. To the east of the pulpit, one box pew dates from the 18th century, another from the 19th; to the west, there are open benches. The church's chest is dated 1804, and there are hat pegs on the walls.
