Melin Cefn Coch was probably built in the late 18th century, and is shown as disused on the 1st edition 25-inch O.S. map of 1889. The tapered and partially rendered rubblestone tower stands on a low rocky mound, and less than two storeys remain, possibly as a result of removing the machinery and major timbers. Both door openings and one remaining window have cambered lintels.
