Cefn Mine

Cefn Mine is a stone building that has been rendered and whitewashed, topped with a slate roof. It features three tall stacks on the front range and a gable stack at the rear. The structure has two storeys, attics, and a cellar, consisting of two parallel ranges, with the later rear range displaying exposed stonework. The front elevation has six window bays, with four bays on the right between gable stacks and an extension of two bays on the left. The entrance is located within a 19th-century glazed porch that has patterned slating and decorative bargeboards, positioned on the fourth bay towards the left of the main elevation. It includes a part-glazed door with a fanlight featuring intersecting glazing bars above. The building has twelve-paned sash windows throughout, with horns on those in the added two left bays, and four catslide dormer windows. The parallel rear range likely dates from the 18th century or early 19th century, consisting of three bays, two storeys, and attics, and it adjoins the stair tower of the original range at the northern end.

While not accessible during the inspection, it is reported by the Royal Commission on the Ancient and Historical Monuments of Wales to have a significant fireplace in the southeast room dating from around 1600 or earlier, along with stop-chamfered ceiling beams. Additionally, there is a notable staircase from around 1700 located in a rear wing opposite the main entrance. The cellars, which date from the 17th century, are still intact.
