This polygon covers the Magna Science Adventure Park. It is located on the site of the Templeborough steel works. The steelworks closed in 1993. The melting shop has been reused as the Magna Centre which opened in 2001. The steelworks was originally opened in 1917. The 1892 OS map shows the terraced housing beginning to built along Sheffield Road. By 1905, more housing and also a pub and chapel are in evidence. However, soon the steelworks was to dominate the area. Prior to housing the area was agricultural. The 1st edition OS map of 1854 depicts thin strip fields with curving boundaries indicative of enclosure from medieval open fields. The site is adjacent to Templeborough Roman fort. Hunter (1831) makes reference to some earthworks in the area but little s known of them. Legibility of the former landscape is invisible.
