Capel Tabernacl (Tabernacle Welsh Baptist Chapel), including forecourt walls and railings

The Capel Tabernacl (Tabernacle Welsh Baptist Chapel) is a late 19th-century building in a Classical style. It is constructed with cement-rendered elevations, painted, and has a slate roof. The main entrance faces south.

The central portion of the front elevation features a broken triangular pediment with modillions. This is flanked by three tall, semi-circular headed windows on the upper floor, each with pilasters, capitals, archivolts, and keystones. A band at window sill level is ornamented with paterae, and a central panel displays the date 1875. The ground floor is rusticated with two semi-circular headed doorways, each with moulded archivolts, keystones, and pilasters. The end bays of the main elevation are slightly recessed and have sloping parapets that rise to meet the central pediment. The eaves have a cornice with modillions and pilasters. Each bay features a blind, paired, semi-circular headed opening on the first floor, with moulded archivolts, keystones, and pilasters, and paired segmental headed openings on the ground floor.

The south-west elevation has five bays. The southern bay’s fenestration is similar to the end bays of the front elevation. The four northern bays contain round-headed sash windows with radiating tracery above and below. The north-east side elevation is also similar, except for a single-storey addition of the early 20th century in a richer Baroque style, with a hipped roof masked by a crowning entablature. A projecting porch is located at the southern end of this elevation, with a rusticated base and doorways with shouldered architraves in each side wall, set behind an Ionic portico on a curve.

The north-east side elevation is composed of several bays. The first contains a sash window with three panes, an architrave, and a cornice on consoles. The second has a projecting rusticated bay containing a large semi-circular headed window with archivolt, giant keystone, and a broken segmental pediment on consoles. The third bay mirrors the first. The fourth has a round-headed, rusticated doorway with an Ionic porch. The fifth bay is a canted bay window with rusticated pilasters and sash lights with glazing bars and horns. At the northern end of the north-east elevation, behind a single-storey side wing, is a two-storey wing with a hipped slate roof, modillions, and angel pilasters. This wing presents three round-headed sash windows, each with archivolts, pilasters, and keystones.

The chapel's forecourt is enclosed by a low stone rubble wall with ashlar coping. Ashlar gate piers have coping in the form of four gablets, and the iron gates have uprights rising alternately to above the lock and top rails, with fleur-de-lys finials. The group value lies in the chapel’s architectural coherence and its relationship to the forecourt.
