Modern business park on the site of a hospital for infectious diseases. The hospital building itself was quite small with surrounding grounds. The grounds were later used as allotment gardens which area likely to have been associated with the colliery housing at Wharncliffe Silkstone. Before the founding of the hospital this was an area of piecemeal enclosure of an uncertain date. It probably wasn’t enclosed in the early medieval period as there was little enclosed land recorded in the Domesday Book for Pilley and Tankersley. The origin of the former moorland landscape is uncertain though this area is likely to be moorland by the Roman period (see Bevan 2003 for discussion of environmental evidence in region). There is no legibility of previous land uses in the current layout of the business park.
