Bethel Baptist Chapel & schoolroom, including gates & railings to entrance

Bethel Baptist Chapel and schoolroom, built in 1840 and enlarged in 1850, is designed in an Italianate classical style. The chapel features a stuccoed pedimented end facade with a giant order of Roman Doric pilasters. The side elevations are two-storey with three windows and topped by a slate roof. The south front displays an oval pediment plaque that reads 'Bethel Baptist Chapel built 1840 enlarged 1850', along with a moulded pediment and a plain entablature. The pilasters have fluted necks and there are three bays between them. The arch-headed window includes moulded arches, keystones, and an impost band. The outer windows are full-length, while the centre window is half-length, featuring 'Florentine' timber tracery with two arched lights and a roundel above. The centre window has pilaster jambs, and the outer windows have sill bands. The entrance consists of double panelled doors without an overlight, set within a large Roman Doric stucco balustraded porch that is supported by two fluted columns, with pilaster responds and an entablature adorned with triglyphs and mutules.

The sides of the chapel are plain, with arched upper windows and a cambered-headed lower window. The rear has two long arched windows and a small gable plaque that reads 'Bethel Baptist Chapel 1840'.

Attached to the west of the chapel is a late 19th-century schoolroom, which has a canted three-sided front and is stuccoed beneath a slate hipped roof. The front features an arched door and three small arched lights above. Each canted side wall has two long arched windows, although the southeast wall is obscured by a later addition.

In front of the chapel and schoolroom is a yellow and black patterned brick wall with low cast-iron gate piers, stamped 'J Powell Llanelly', which includes both single and double gates.
