A three-storey red sandstone corn mill, believed to have origins in the fourteenth century. The current building may date from 1709 or 1769 when it was rebuilt by Philip Yorke. Latterly, water was supplied in a leat, about 1.6km long, from a weir on the River Clywedog to a long, thin pond, some 135m in length and 12m wide, adjacent to the mill. The mill closed in 1940, but the building has been restored as a visitor centre.
