A "Flour Mill (disused)" is depicted and annotated on the 1871 Ordnance Survey 25in map; a boggy pond lay some 120m to the south west. In the pond, a symbol and legend indicating "Site of Ancient Furnaces (Discovered 1840)" suggest that the pond may have been constructed then. On the 1899 map the mill building is annotated "Or Yo Works (Chemical)" and the mill pond, sluice and leat appear to be in use.
