Water powered mill, associated with the nearby Dolgarth Slate Quarry (NPRN 420411). Slate was brought to the mill via a counterbalance incline with the finished product carted out of the valley.

The mill building, measuring some 13m by 10m is stone built and thought to have earlier origin, with the wheel pit added to the south gable end of the building in the late 19th century. Water was fed directly fromthe nearby Nant Dolgeth via an aqueduct and fed back into the river via a slate covered tailrace leat.

The building survives as a ruin.
