Capel Panteg and attached vestry to left

This is a late 19th-century chapel of stucco construction, situated with an attached vestry and stable to its left. The chapel's front facade features a plinth, quoins, and moulded arches, topped by a slate roof with deep eaves. It has two arched windows and two arched outer doors. The windows are slender with small panes, featuring radiating bars at the top of the arches. The boarded doors are similarly designed, each with a radiating-bar fanlight above. A plaque is positioned in the centre of the facade. The rear of the chapel is built of rubble stone.

The attached vestry and stable, set back to the left, is also of rubble stone with brick surrounds. A structural joint and corner stones in the centre suggest the left side may originally have been a free-standing structure. A plaque inscribed "T.L. 1868" is present. The upper storey of the vestry has four 12-pane windows; the lower storey has a boarded door with an overlight to the centre-right, a 16-pane sash further to the right, and a second boarded door to the extreme right, accessed by slate steps and lacking an overlight.

Inside, the chapel features a pulpit on the wall facing the entrance, and a three-sided gallery supported by ten plain, thin iron columns. The gallery's cornice is marbled, and the frontal panel is painted and grained with long panels, rebated angles, and inner raised darker panels with similar rebating. Panelled piers are positioned between the long panels and in the curved corners, with a clock incorporated into the central pier. A fine set of painted box pews are arranged in four rows along the back wall, with ramped ends and a grained panelled frontage, divided into three blocks with aisles in between. The gallery pews are also painted and panelled with shaped bench ends. A single 9-pane sash window is located in the east wall. The ceiling is flat and plain.

A particularly unusual set fawr and pulpit arrangement is constructed of painted and grained wood. The square pulpit features panelled sides below squat balustrades of turned balusters with corner newels and finials; steps are provided on the right side only. The set fawr is a fully enclosed rectangular structure in front of the pulpit, with a bench around and a panelled back. Single box pews are positioned on either side of the set fawr and in front of the pulpit, and painted in different colours. Those on the sides have doors in canted angles, while those flanking the pulpit have doors leading directly from an added entrance lobby. A tall, horizontally boarded back in a marbled reeded frame, with pilaster sides and an ogee pointed head with a finial, sits behind the pulpit.
