A water-powered fulling mill, possibly of eighteenth century date, with walls are of split rubble masonry set in clay mortar under a slate roof. It appears that the mill was supplied with water from the tail-race of Felin Rhyd-y-pandy corn mill (nprn 24750), some 180m to the north east. When visited in November 1983, the building was in ruins, with fragments of machinery surviving. A house, 'Pen-ddintir' ('top of the tentering field') lies adjacent to the north.
