St John's Church is located within a small curvilinear churchyard, with the Afon Clettwr some 40m from its estern boundary. The church is depicted as a chapel of ease on 1889 Ordnance Survey mapping. A later nineteenth-century Sunday School abutts the churchyard's north-west boundary.

The church, constucted in 1884-1885, consists of nave, chancel and tower. The nave has pyramid-capped angles and Y-tracery windows. The tower has a corbelled parapet.
