Modern business park, built on site of the earliest phases of Newton and Chambers' Thorncliffe Works. This multi-product complex was involved in the extraction of both local coal and ironstone as well as the production of iron blast furnaces and the production of iron castings and products including stove grates, ranges and (during the 2nd world war) 'Churchill' tanks. The complex was first established in at Thorncliffe in 1793 (Jones 1999, 148). The site included blast furnaces, coke ovens and factories as well as substantial rail yards. No legibility within this polygon which has been completely cleared and redeveloped.
