The Cyclops works of Charles Cammell were first built on this site in 1846 alongside the slightly earlier works Aetna Works of Spear and Jackson to the north East. The works were sited to take advantage of flat ground and the new railway link. Production began with cementation and crucible processes but by 1861Cammell had taken out a licence to install a Bessemer melting shop. By 1879 the process had been superseded by the Siemens Open Hearth process and Cammells had between 6 to 8 furnaces. (All from Hey 1998 152-153). The works eventually expanded to the north of this site. This site appears to have been redeveloped after the 1987 OS survey. Little legibility of earlier types.
