Brithdir Independent Chapel including Low Front Walls, Railings and Gates

Brithdir Independent Chapel, built in 1860, is a 4-bay rectangular chapel constructed of rough-dressed rubble with dressed slate-stone detailing and a shallow-pitched slate roof. The symmetrical front features plain bargeboards that return to create a pedimental effect. In the center, there is an oculus with an inscribed plaque that reads: 'Brithdir Independent Chapel, erected 1860.' Below this is a single-storey projecting porch with a flat roof and plain entablature. The entrance is depressed-arched, with plain projecting imposts and shallow rubble pilasters, leading to recessed boarded doors. Flanking the entrance are round-arched windows with similar imposts and a plain cill band, featuring 9-pane fixed glazing with Y heads. The sides of the chapel have four tall, recessed 8-pane sash windows with projecting slate cills. The east end wall is rendered. Attached to this gable end is a 5-sided single-storey bay, which serves as a contemporary school room, featuring boarded doors on the left and right and 12-pane sash windows on the three remaining sides. There is also an off-centre rubble chimney with a modern upper section.

The chapel has low forecourt walls that are slate-coped, with plain decorative iron railings at the front. There are similar gates in the center and an additional gate leading to the churchyard on the right.

Inside, the chapel features a plain interior with pitch pine pews and dado panelling. The school room retains its original benches and lectern.
