Small irregular enclosures with sinuous boundaries, which have been later subdivided, around the small farmsteads at Falthwaite. Probably enclosed at an early date from ancient woodland. The 'thwaite' placename indicates a clearing (Field 1972, 233). The date of origin for the woodland is unknown. Legibility of the former woodland is partial as sinuous boundaries remain as do wooded areas along the rivers. In the late 13th century the monks of Pontefract established monastic grange at Falthwaite (Umpleby 2000, 173). A 18th, possibly 17th, century farmhouse remains on this site (SMR PIN1490). Within the polygon is the possible site of a late medieval water powered bloomery. The site would have worked ironstone which was abundant in the area. There is a specific reference to the mining of ironstone in Bagger Wood (HSY6303) in 1522. The bloomery was probably in production from the 14th century to around 1620. (ibid, 175).
