Fields which were associated with a linen works and bleachery at Redbrook. These fields would have been used to lay out the linen between chemical treatments. The bleachworks was in operation from about 1790, leased by John Pickering a linen manufacturer. By 1871 linen weaving was also carried out on the site and by 1912 some dying was also taking place. Bleaching had probably stopped by 1929 and textile manufacturing by 1957. (Taylor 1993,53-4). There is no legibility of the former industrial site or the former assarted woodland. Between 1938 and 1973 the layout of the field boundaries in this area changed probably due to opencast coal mining.
