Part of Netherwood Country Park, established on a former extractive site. 1855 maps mark a small brick kiln within this polygon. By 1892 this had developed into a Sanitary Tube works associated with the adjacent Darfield Main Colliery. By 1930 the tube works was replaced by spoil heaps from the colliery. There is partial legibility of the spoil heap in the remaining earthworks on the site. There is no legibility of the former piecemeal enclosures.
