Land that was part of Tankersley deer park between 1303 and around 1730. The area was sparely settled in the early medieval period (very little cultivated land in the nearby settlements recorded in the Domesday Book) so the land before the development of the park was probably unenclosed. Hugh de Elland was granted the rights to free warren in 1303 and formed a deer park (Hey 1986, 82). The park retained its character for several hundred years and an engraving dating to around 1739 shows this area to be still parkland (copy in Hey 1986, 82). After this point disemparkment began and the formal parkland reduced in size. Regular straight sided enclosures are marked within this polygon on maps thought to date to 1772 (copy in James 2005). Maps from 1840 (ibid) show this polygon to be covered by a number of annular spoil heaps. Mining took place at Bell Ground from 1823 to c.1850 (Jones 1995, 95-7). There is partial legibility of the former enclosed landscape as the site was returned to agricultural use after the levelling of the bell pits. The origin of the former moorland landscape is uncertain.
