Now occupied by road junction serving Meadowhall Interchange this polygon represents the site of Blackburn Forge and its associated Dam as shown on the first edition 6 inch to the mile OS. Miller (1949, 100) records the forge as in existence from at least 1794 to 1853 but it is no longer shown by 1894 O 25 inch mapping by which time the site has been cleared and the Brook has been canalised to a position further east. The site appears to have remained undeveloped until construction of the present roads. Nb. SMR reference for Blackburn Forge PRN 1716
