Mill which was built in 1743 by John Cockshutt as part of Wortley Iron Works which consisted of several wire mills and forges along the river Don. Rolled sheet Iron was produced on the site and Tin plating also took place between 1174 and 1814. The mill closed in around 1870. (Bayliss 1997) The buildings of the mill haven't survived but the dam remains in a slightly altered form. This was probably an area of piecemeal enclosure on the edge of Green Moor. There is no legibility of former enclosures.
