Thorp Mill, Royton was built by Ralph Taylor at Thorp Clough in 1764. This is reputed to be the first cotton mill in Lancashire to be powered by water. Ralph Taylor bought three existing cottages which he converted into a mill. This was a carding mill, and was powered by a water wheel driven from Thorp Clough, a tributary of the River Irk. The mill closed in 1788 when the mill and contents were advertised for sale by the then owner James Taylor. It was advertised again in 1792, and the buildings reverted to cottages, and were subsequently demolished.
