Kilgetty Colliery Engine House

Kilgetty Colliery Engine House is a 19th-century structure that served the Engine Pit, which was 49 fathoms deep. The engine house measures approximately 7 meters by 5 meters and is built on an irregular sandstone base that is integrated into the slope. The superstructure is made of red brick and features a gabled roof covered with green slate. The sandstone base is believed to be from an earlier engine house, possibly associated with the Neath Abbey Iron Company engine, which was purchased around 1811.

At the front northwest side, there are three square openings typical of beam-engine houses from this period, along with one opening on the right side. An external stone staircase leads up to the doorway on the right. The upper and front sections of the building have been modified with brickwork, likely in the late 19th century or later, to accommodate a new winding engine. This brickwork extends outward in two narrow baffles at the front, allowing the roof to overhang the façade and create a boarded gable. Below this, a planked wall rises from the original stone plinth and features a tall opening with hinges on either side, through which winding cables would have passed. This opening has been partially blocked with timber, and a small-paned steel window has been installed above it. Additionally, there are two more windows in the upper part: a 19th-century cast-iron window at the rear and a late 20th-century window towards the rear of the northeast side.
