A single-storey mill at the tidal limit on a stream draining Llyn Maelog at its north end. It was 9.2 by 6.4 metres in plan, with two rooms. The wheel pit would have accommodated an undershot wheel 3.6 metres in diameter and 1 metre wide. In 1975 there was no internal machinery and the building was in use as a stable.
