Hermon Chapel

Hermon Chapel is a Nonconformist chapel and Sunday school, dated 1862, designed by Reverend Thomas Thomas of Llandor. The building is constructed of Flemish bond red brick with a stuccoed front and rendered at the back, topped with a slate roof featuring gabled ends. The chapel has a rectangular auditorium with a gallery on three sides and an entrance at the southwest end beneath the gallery, while the northeast end houses the Sunday school.

In a Classical Italianate style, the exterior is single storey with a tetrastyle pedimented southwest front that includes an inscription panel in the tympanum. The façade features giant pilasters, with the outer bays containing tall round-headed windows that have moulded architraves, small keyblocks, and bracketed cills. The central tripartite window has round-headed lights above a round-headed pilastered doorway, which has a moulded extrados, keyblock, and panelled double doors with arched top panels. The sides and rear of the chapel are adorned with tall round-headed windows, all of which retain their original frames with foiled tracery over two lights. The northeast end includes a single-storey Sunday school with 12-pane sash windows.

Inside, the chapel features a gallery on three sides supported by thin cast-iron columns, with a panelled front. The auditorium has an intricately panelled ceiling with a central leaf rose. The deacons' seat and box pews are intact, including those in the gallery. At the northeast end, there is a rostrum with a large organ, built in 1909 by Blackett and Howden.

Hermon Chapel is an exceptionally complete example of a chapel interior from this period and type, and it is also significant as a work of Reverend Thomas Thomas, one of the leading and most prolific Welsh chapel architects of the Victorian era.
