Capel Als,including railings, piers & gates to Chapel Enclosure

Capel Als is an unpainted stucco Italianate building dating from the 19th century. It features two-storey elevations with four-window sides and a three-bay front, where the center is slightly recessed. The building has a plain cornice and parapet, with the center parapet inscribed 'Capel Als' and topped with a gabled capstone. The hipped slate roof has boarded eaves at the sides and rear, a parapet at the front, and short side returns.

The front elevation includes arched windows set in architraves with imposts, keystones, and margin-glazed sashes. There is a sill band beneath the first floor, and paired pilasters frame the outer bays of the first floor. The ground floor features simplified paired strips at the outer angles, with corresponding inner pairs obscured by a porch. The outer bays of the first floor have single arched windows, while the recessed center contains a triplet of narrow windows. The ground floor has a single narrow light on each side, leading to a porch with two five-sided hipped-roofed projections on either side of an open two-bay porch with a lean-to roof and a central cast-iron column. The five-sided sections have three narrow arched lights on their front faces and doors on their inner faces. Inside the porch, there is a large window with 20th-century Gothic glazing bars and stained glass.

The sides of the main front have a short return of the cornice and parapet, with a channel-rusticated angle pier and a stair projection featuring channel-rusticated angles, paired outer windows, and long stair-lights on the north-facing sides. These sections have hipped lean-to roofs. The side elevations beyond are plain with four windows, featuring cambered-headed lower windows and arch-headed upper windows in raised frames. There is a sill band and a channelled angle pier on the west side. The rear of the building is two storeys high with two windows, including arched upper windows and a cambered-headed window and door below.

The chapel enclosure is surrounded by an extensive set of cast-iron spearhead railings and gates, which are complemented by cast-iron Gothic gatepiers. The railings are set on dwarf rubble walls with cast-iron coping. The iron piers are marked 'Thomas and Clement, Llanelly', and the coping is dated 1894. The railings extend in front of the Sunday School to the east.
