Capel Bethania, chapel house and schoolroom

Capel Bethania comprises a chapel, chapel house, schoolroom, and stable range set around a unified group. The principal structure is a rectangular-plan chapel with a two-storey chapel house set back and attached to its left (south-west) end, and a schoolroom range to the right. These are linked by a short axial corridor which provides access to the chapel and is fronted by a pedimented porch. To the rear of the schoolroom stands a single-storey stable range with gabled wings to either side.

The buildings are constructed of snecked rubble masonry with gritstone dressings beneath slate roofs with projecting eaves and verges and slate ridge tiles. The chapel house has rectangular rendered stacks with caps—one running along the ridge and one at the far south-west end. The chapel and chapel house roofs are hipped; the schoolroom roof is pitched.

The principal south-east elevation features the main entrance to the chapel, set within a slightly advanced architrave with a cornice broken at centre and surmounted by a pediment. The entrance itself is segmentally arched, framed by gritstone ashlar piers with plinth and stone cap supporting a voussoir arch. Double panelled doors and a fanlight with vertical glazing bars occupy the opening. The chapel rises through four bays with tall twelve-pane hornless sash windows.

The schoolroom sits to the right. Its entrance is through a gabled porch in the gable end, containing square-headed boarded doors beneath a rectangular fan with glazing bars. Stepped rectangular lights of two and six panes sit in the gable apex above the entrance. Flanking the porch are tall eighteen-pane horned sash windows with stone lintels and slate sills. The north-east wall of the schoolroom has four similarly detailed windows. The rear range (originally the stables) has a single six-pane sash window and modern doors.

The chapel house at the south-west end is a two-storey, three-window range with a central doorway. The round-headed voussoir arched doorway contains a panelled door beneath a rectangular fanlight with glazing bars. Windows are slightly recessed sashes with stone lintels and slate sills: four-panes over the entrance and six-pane flanking windows. The rear elevation shows scattered fenestration of two and four-pane sashes and a tall stair light to the north-east end.

The interior is accessed through the pedimented entrance into an axial corridor. Panelled doors on the left-hand wall lead to triangular side vestibules with half-glazed doors opening into the chapel beyond.

The set fawr (pulpit platform) occupies the opposite end of the chapel, raised by two steps. It is rectangular with opposing side entrances, the lower part with plain recessed panels and the upper part with pierced decorative recessed panels beneath a moulded rail. The pulpit itself is raised by three steps with side entrances flanked by turned newels. The front comprises three bays, the central bay advanced and canted. It features recessed panelling with ornate foliate carving in the advanced central bay and turned balusters beneath a moulded rail in the side bays.

Chapel fittings are of pitch pine. Pews are raking and follow the chapel's shape, with a central bank facing the set fawr. Walls are plastered and painted with tongued and grooved panelling beneath a moulded dado at the lower part. The set fawr is flanked by panelled doors—the left leading to a cupboard and the right to the chapel house. Between these, the panelling is interrupted by a tall screen of recessed panelling broken by a fluted frieze and raised at its ends to be topped by engaged globe finials, and in the centre by a moulded triangular pediment. The ceiling is coved, its central part formed by deeply recessed tongued and grooved panels with moulded dividers; front and rear panels incorporate ornate metal ventilation grilles. A doorway to the right of the corridor opens into the schoolroom.

The schoolroom retains its original benches and rectangular teachers' reading desk with side entrances. The desk's angles are articulated by square newel posts topped by ball finials, with tongued and grooved panelling beneath a moulded rail forming the front and sides. Walls are half tongued and grooved, and original gas brackets remain behind the teacher's desk.
