Cleared / development site (Jessops Riverside). Polygon records extent of water powered site that took its head waters from above the surviving 'Brightside Weir'. Crossley (1989) records a succession of mills at this location the earliest being the corn mill recorded in 1328 belonging to Thomas de Furnival. By the mid 16th century a cutlers wheel has joined the corn mill (the corn mill is last recorded in 1690). These sites remain in use as cutlery wheels until the mid 18th century when the emphasis seems to switch to forging with the first mention of 'Brightside Tilt'. From around 1750 the site was tenanted by William Booth and company who developed a major works on this site, which by 1850 had been bought by new owners William Jessop and son who introduced steam power. An illustration of 1858 (reproduced in Badcock 2000) shows an integrated steel production complex (typical of the period with cementation and crucible ranges) to the immediate north of the tilt forge complex. The steelworks were demolished in the late 1980s and this site is currently under development as a business park. Archaeological excavations in recent years revealed cementation furnaces and tilt forge timbers, however at the time of writing (March 2005) no report has been produced by the excavators. 'From' date reflects adoption of steam power for forging operations.
