Grassed over spoil heaps from Barrow Colliery that are first mapped at this extent in 1966. The colliery operated between 1873 and 1985 (Gill 2007b). A mineral railway ran through the south east edge of the polygon and connected the colliery to Barnsley. This was previously an area of piecemeal enclosure at the edge of the medieval town fields associated with Worsbrough. It is possible that this was part of the town field. There is no legibility of the previous landscape beneath the spoil heaps.
