Bethel Baptist Chapel and attached vestry.

Bethel Baptist Chapel and its attached vestry is a building constructed in unpainted stucco with a slate hipped roof made of grey slates and featuring flat eaves. The chapel is two storeys high and has a three-window front with small arched windows that include Florentine timber tracery (two-light and roundel) dating from 1904, all surrounded by bead-moulded frames. The central arched doorway has a panelled double door and a leaded crescent overlight, also from 1904, and the building features leaded glazing. The chapel stands on a raised plinth with channelled angle piers. A date plaque above the door reads, "Bethel Baptist Chapel Built 1797 Rebuilt 1840 Renovated 1904." The end walls are rendered, and there is a plaque on the west wall dedicated to Rev William Thomas, who died in 1813 and was the first Unitarian Minister of this congregation. The inscription beneath the plaque states: "Believing one true living God/ And Christ his Son his paths to tred/ General Baptist I preferred/ In peace I deid I have not err'd." The rear of the chapel is made of rubble stone and features two arched windows with stone voussoirs and square impost blocks, similar to the Florentine tracery at the front.

The rear northeast vestry is constructed of whitewashed rubble stone and has a north end stack. It features a half-gable to the south with steps leading up to the door. The east side has a basement door to the right and a 20th-century window in the centre of the first floor, while the rear wall is blank.

Inside, the chapel is largely from 1904, except for five iron columns with leaf capitals that support the three-sided gallery, which are from the 19th century. The interior has a panelled ceiling and a gallery with a gently curved main front made of timber, featuring a plain cornice and small horizontal panels under open panels with short turned balusters. The plain pulpit has steps on each side, ball finials, shaped balusters, and a shallow-curved front, with paneling below small square balusters. There are two brass oil lamps present. The pews are arranged in three blocks, with curved seating and some inward-facing pews on either side of the pulpit. The gallery pews are raked and curved. The lobby contains a three-light leaded window with coloured glass and double doors on each side, along with a tiled floor and four-panel doors leading to the gallery stairs.
