Description
The Church of St Garmon is a parish church built in the Romanesque style. It features regularly coursed and dressed rubblestone blocks with ashlar dressings, and has slate roofs with coped verges and kneelers on the nave, while the sanctuary is conical to semi-circular. The nave consists of three bays and includes two stepped buttresses on both the north and south walls, as well as diagonal buttresses at the corners.
The windows are two-light, round-arched, and made of cast iron with latticed designs, featuring plain chamfered shafts and capitals set in round-headed openings that are connected by continuous impost banding. The west end of the church has a central round-headed doorway with the date "1842" above it, leading to a recessed boarded door. There are narrow round-headed windows on either side of the doorway, also linked by continuous impost banding. Above this, a string course with a slight projection at the center of the wall supports a two-light window similar to those on the north and south walls, which continues upward to form a gabled bellcote with a round-headed opening that houses a bell.
The semi-circular apsidal sanctuary has three small round-headed windows linked by continuous cill and impost bands, featuring red stained glass in the outer quarries. Inside, the church has a simple design with a collar and tie beam roof structure and boarding on the rafters. A half-height screen creates a small internal lobby at the west end, and the floor is made of slate.
The fittings from the 19th century include a rail for the raised sanctuary, a pulpit, a reading desk, and benches. There is a 17th-century communion table with a 20th-century top, and a font with carved lettering that reads "CAPEL. SANT. GARMON. BETWS. 1614," which also features a small four-leaved flower carved between "CAPEL" and the date. Additionally, there are 18th-century wall tablets and a brass memorial on the north wall dedicated to John Rowlands, who died in 1703.
