Originally built by the Firths as 'Tinsley Steel Works', a crucible steel production facility. In 1920 (after the invention of Stainless steel) production switched to the new material given the trade name 'Staybrite' by the firm. This polygon shows the surviving buildings from the original works. Prior to its industrialisation this area was characterised by 'strip' fields formed from the enclosure of medieval open fields. No legibility of pre industrial landscape.
