Tabernacle Chapel including attached Hall and forecourt railings

The Tabernacle Chapel, which includes an attached hall and forecourt railings, is a significant building constructed in painted stucco. It features a classicising front that rises two storeys high, topped with an entablature and parapet inscribed with "Tabernacle," "Built 1821," and "Rebuilt 1865." The upper part of the chapel has a group of four round-headed windows set within a recessed centre, while a balustrade separates the projecting end stair towers, which are adorned with windows enclosed in pedimented architraves. On the ground floor, there are four round-headed doorways at the centre, flanked by blind round-headed windows that are enclosed by channelled rustication.

To the right, there is a lower two-storey vestry or schoolroom block that is set back but designed in a similar style and using similar materials. This block has a hipped slate roof that sits behind the parapet. The top floor features three round-headed windows with keystones, while the ground floor has a central round-headed doorway flanked by rusticated pilasters and a window on each side.

The forecourt is defined by iron railings with gates at the centre and both ends, which are supported by gatepiers topped with acorn finials.

Inside, there is a shallow lobby with a wood and glass screen leading to an inner lobby, which also features a similar screen. The lobby provides access to the stair towers. The main body of the chapel boasts a flat coffered ceiling with a large fretted metal rose. A gallery encircles all four sides, supported by iron columns with floral capitals and featuring a fretted metal balustrade. At the rear, a broad arch leads to the organ recess, below which is a wooden pulpit and a set fawr enclosure with a wrought iron balustrade. The chapel contains wooden pews and features early 20th-century stained glass in the side windows, depicting Virtues, as well as two front windows illustrating the Baptism of Christ and the Last Supper.
