Warehousing and retail space on the site of Smithies colliery. This has been known as Smithies Main, Marsden Main and Wallsend Colliery. Thomas Marsden owned the nearby Smithies Valley Papermill and may be the same Marsden who owned this colliery in 1873. The colliery closed in 1927. (Goodchild 1998, 70-1). The colliery was built on an area of surveyed enclosure that was probably part of the 1794 parliamentary award (date from English 1985, 99). On 1775 maps this area is marked as unenclosed common. There is fragmentary legibility of the surveyed countryside as Wakefield road runs along its turnpiked route.
