Interior
Nave with chancel of 10 roof bays, defined by C11, C15 or early C16 arch-braced collar beam trusses rising from stone corbels. Cusped raking struts to all but the two most easterly trusses, where an original ceiling is assumed. Two tiers of purlins and exposed rafters. A single step up defines the chancel, with a further step into the sanctuary, both having C19 encaustic floor tiles. The 4-bay arcade opens to the 8-bay N aisle. Octagonal columns with recessed angle on each face, and ovolo capitals carrying the depressed arches of 2 chamfered orders, all characteristic of the area. The 8 similar trusses of the aisle are without cusped upper parts and corbels exist on the arcade side only. The W bay is partitioned off as a vestry. An additional corbel carved with the letters RE above the E pier, corresponding to a similar corbel on the chancel side with the date 1615, and stubs of others suggest an earlier roofing system.
Fittings: altar rail, softwood, side cusped panels; pulpit, C19 octagonal, with a ballflower enriched cornice, set up on a stone base; readers desk, two sided, also C19. The lectern is free standing. The pews in the nave are C19, but in the N aisle, a very fine C15 group of 5 stalls with miserecords carved with roses and lilies, and the arms carved with upturned masks. Also a corresponding book desk, 3 stalls long, with a carved frontal and carved pew end in the form of two clerics standing back to back, each displaying a shield. It has been claimed that the stalls came from either the pilgrimage church at Clynnog, or from Bardsey.
Font: a small octagonal bowl, probably medieval but remounted in the C19.
Glass: E window, Our Lord and 4 Evangelists, c1880, in memory of Margaret Evans of Broom Hall; S side, eastern window, 1924, 2nd window to Rev David Jones, vicar, d.1926, donated by his children. The E window of the N aisle, Faith Hope and Charity, 1885, to Margaret Casson, Blaidd Bwll (Mer); E window of N side, interesting glass of c1894, in memory of Rhoda Carreg of Carreg.
