Bryn Seion Chapel

Coursed and squared stone and ashlar to entrance front, with slate roof with tiled cresting. Entrance in S-facing gable, and 6-window range facing street, articulated by pilaster buttresses which have moulded capitals and plain imposts forming hood moulds to round-headed windows. These are divided as 2-round-headed lights, with timber columnar mullions. The coped gable pediments the S-facing gable, which has paired doorways, each of which is flanked by 8-pane windows. All the openings have pedimented heads, but the doorways have full architraves, with Tuscan pilasters on high bases.
