Capel Horeb and chapel house including railings and gates

This is a Presbyterian chapel with an attached chapel house, including iron railings and gates. The chapel dates from the 18th century and is constructed primarily of dressed stone with pale grey quoins and dressings, while the side elevations are of coursed stone rubble. The front of the chapel, which faces west towards the village, has a gabled design and features round-headed openings with keystones. Four tall, two-light windows with small-pane glazing are present, each with a continuous moulded label running across the elevation of the chapel. Two round-headed windows are grouped towards the centre of the front elevation, with one in each outer bay. Two double-leaf panelled doors with plain overlights are situated between the outer windows and the central window grouping. The south lateral wall has four-pane sash windows on two levels. The rear of the chapel is polygonal, with two tall round-headed windows containing stained glass. The north side of the chapel mirrors the south, and includes a chapel house constructed from matching materials.

Iron railings with fleur-de-lys finials enclose the front of the chapel, along with rectangular stone gatepiers with capstones and double gates facing the road. A smaller gate is located where the railings connect to the chapel house.

The two-storey chapel house has a single window to the front elevation. It features camber-headed four-pane sash windows to each floor, with a low window in the attic. A panelled door is located to the right of the front window. The gable facing the road has a rectangular stone chimney at its apex. Ground and first floor windows are located on the rear (east) of the house. A two-storey rear wing, built up the slope and constructed of similar materials, abuts the rear of the chapel house. This wing features sixteen-pane sash windows. A boarded door is present at the far left (east) end, accessed by a flight of stone steps. Two windows are positioned to the right of the door, set under the eaves; the window to the left has a shallow overlight, while the window to the right is deeply recessed and accommodates a single window.

Inside the chapel, a glazed wooden lobby leads to a wooden staircase ascending to a U-plan gallery supported by iron columns. A wooden panelled frontal is present. A wooden “set fawr” enclosure is also visible. The ceiling is elaborate, with a central rose surrounded by oval panels and corner roses. The rostrum has a back piece featuring Corinthian pilasters.
