Early C19, on the site of an earlier building shown in a print dated 1796, the mill was used to grind corn and to power a circular saw. The roof was raised, perhaps later C19 to provide more space on the grain floor. It was in continuous use until 1942 at which time it was being used to make cattle feed. The mill was restored and opened to the public by Clwyd County Council in 1980.


Rubble with roughly squared quoins, slate roof, 3 storeys. Windows are all horizontally sliding sashes reglazed and restored 1980. Elevation to yard has ground floor entrance with cambered arch with boarded doors and a small window above. The position of a lower steeply pitched roofline is visible in the masonry. Right hand return has a timber external stair leading to a door, a small window to the right and one small window to upper floor. Left hand return has one small centrally placed window to the ground and upper floor, 2 larger windows to first floor. Rear elevation has an overshot cast iron waterwheel with the makers name, R & W Jones Ruabon, fed by a cast iron flume by the same makers. There is a small window and a ventilation slit above the wheel and the line of the former roof can be seen in the masonry. The flume connects to a sluice with gates renewed 1980.


Not accessible at time of 1995 survey, but recorded as containing working machinery restored with some replacements, 1980. Ground floor has millstones set into the floor, drive floor to rear with mill machinery. First floor retains further mill stones and upper floor has sack hoists etc.
