Site of Park Gate Colliery which was operating between 1854 and 1878 (Gill 2007b). The site still retains the character of the mine with spoil heaps and reservoirs so legibility is significant. The site is now reused as part of the Tankersley Park Golf Course. Before the sinking of the mine this would have been enclosed land outside of the boundary of the deer park. It is shown as small hedged enclosures on an etching of Tankersley park dated c.1730 (reproduced in Jones 1995, 81). The date of this enclosure is uncertain but it probably post dates the formation of the park in 1303 (date from Hey 1986, 81) as the enclosures appear to run off the edge of the park wall. There is no legibility of these enclosures or the probable moor land that pre dated them. The origin of the former moorland landscape is uncertain.
