Zion Baptist Chapel, including Forecourt Railings

This is a Baptist Chapel, constructed in 1857-8 by Henry Rogers of Llanelli. It is built of squared rubble stone with dressings in blue lias ashlar, and has a slate roof. The front is designed in an Italianate Classical style, featuring a pedimented facade with giant Tuscan pilasters, a plain cornice, and a pediment bearing an oval plaque marking the date of construction. The three-bay, two-storey front has arch-headed windows on the upper floor, with moulded arches and keystones. The outer windows are margin-glazed sashes with impost bands and jambs framing square-headed sashes below. A lower sill-band and ashlar rustication are visible beneath the windows. The central window is wider, lacking impost bands but featuring pilaster jambs, a bracketed sill, and a decorative wooden window with two arched lights and a roundel above. The ground floor entrance consists of double panelled doors set within a large painted timber porch with two columns and pilaster responds. Side elevations are plain, two-storey, and four-window, with arched windows above and flat-headed windows below, all featuring sashes with narrow marginal and centre panes. A blocked fourth bay is present on the east side due to an attached house. The rear elevation has a two-window centre projection and single-window ranges on each side, culminating in a shouldered gable with stucco hoodmoulds.

The interior retains a panelled gallery on three sides, supported by three by three iron columns. Original box pews are present. A fourth gallery, behind the pulpit, is lower and sits over a panelled wall with doors leading to gallery stairs. This gallery, along with the organ and a panelled 'set fawr', was added in 1929. At the rear of the choir gallery is a wall-arcade of Corinthian columns framing a broad, depressed-arched recess for the organ, with narrower flanking bays featuring depressed arches and keystones. The outer columns are paired with Corinthian piers, and curved-pedimented timber doorcases lead to the gallery stairs. Above the wall-arcade is an ornate cornice, not continued on the side walls, which instead have a deep coved cornice. A flat boarded ceiling is divided into panels by transverse and diagonal ribs, with central roses. A built-in immersion font sits beneath the pulpit. To the north end of the chapel are various chapel rooms and gallery stairs.

Memorial tablets commemorate three notable ministers, including David Bowen (1774-1853), the first minister, and Jubilee Young (1931-57). The front forecourt is enclosed by railings dating from circa 1913, designed to match those of the adjacent Sunday School.
