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 where buildings from the earlier phases of the facility have been levelled. Now mostly car parking with some early 21st century steel-framed buildings. No legibility of earlier landscapes.
