Now a depot for the storage and distribution of 'tower cranes' for hire by major construction projects this site was formerly the site of Grange Mill (Blackburn Brook). Grange Mill (SMR PRN 1714) was thought by the Rev J Eastwood to be, "doubtless situated on the very spot where the monks of Kirkstead (Abbey Grange) placed their mill nearly seven hundred years ago." (quoted in Miller 1949, p98 the chief source of information for this polygon). However the earliest certain documentary evidence for this mill comes from 1715 when there were two mills here leased to Samuel Vintin of Rotherham. At this time these mills were used for the milling of corn (ibid.). Grange Mill burnt down in 1904 and was rebuilt (with the dam filled in) as a farmhouse. The buildings were cleared and will now survive only archaeologically (if at all). Weir survives upstream of this polygon.
