Part of Kilgetty Colliery (nprn 308436), The engine house is first clearly marked on the 1906 25inch O.S. map, but it is probably very much older. The building is an extremely rare example of a colliery winding engine house of a small and inexpensive type. The engine house is about 7 m by 5 m wide, standing on an irregular sandstone plinth built into the slope, with a superstructure of red brick and a gabled green-slate roof. The sandstone base of the structure belongs to an earlier engine house, possibly that for the Neath Abbey Iron Company engine, purchased in c.1811.
