Seion Welsh Presbyterian Chapel

Large rectangular chapel, probably built in 1841 when the former Siloam Chapel was converted for subsequent use as the Women's Institute room. Of rubble on a low rubble plinth and with plain slate roof. Symmetrical E (entrance) front with plain bargeboards to gable. Paired tall, arched windows with 18-pane sashes and radial glazing to heads; marginal glazing. Outer flanking entrances, arched as before with 4-panel raised-and-fielded double-doors and radial fanlights. 3 further arched windows to each of the N, S and W sides, with 20-pane sashes and radial glazing to the heads. All openings have dressed sandstone voussoirs to the arches and the windows projecting stone cills. The W gable end is rendered and has plain stucco stringcourses and architraves. An ex situ stone tablet fixed to the lower L of the E wall has a dedication inscription in Welsh and 'Sion 1819'.

Plain interior with panelled ceiling and tiered seating rising towards the W.
