Groesffordd Marli Chapel

Simple rectangular gabled chapel of limestone rubble with finely-tooled limestone dressings. The front and left side (NW) have grey roughcast; slate roof with plain bargeboards. Symmetrical facade with tall paired, arched windows to the centre and arched flanking entrances. The windows have original 18-pane recessed and unhorned sashes with segmentally-glazed heads; limestone voussoirs and projecting stone cills. The entrances are similarly-arched and have deeply-recessed 6-panel double doors and simple 3-part fanlights. The sides each have 3x18-pane square-headed windows, as before, those to the NW replacements. At the rear is a single-storey early C20 extension of rubble with pitched slate roof; this has a boarded door and a 6-pane window to the L, with a plain brick external chimney. Flanking this are later C20 low WC extensions. Two original E end windows, as before.

Simple fixed, tiered pine pews and a Set Fawr with tripartite architectural back and segmental top. The ceiling is in 3 sections, with the central part segmentally-vaulted; this has moulded plaster-ribbed coffering. Flanking the Set Fawr are leaded inner lights to the windows, in Art Nouveau style.
