Golf Course preserving outstanding evidence of a 'open field' ridge and furrow system complete with furlong groups jointed at right angles. Ridge and furrow earthworks well defined on 1999 Geoinformation Group Aerial Photograph which is taken in 'long shadow' sunlight. The system, appears to be associated with the hamlet of Abdy (SMR PRN 1596-1599inclusive). Abdy is known from the Cartulary of Monk Bretton to have existed in the 13th century (Ryder 1979) The placename is listed by Smith (1961, pt 1 p107) as meaning "property belonging to an abbey". The buildings of the hamlet, according to Ryder in 1979 "expected to be demolished in the near future" dated to the 17th and 18th century but appear from his report to have contained substantial evidence of reused timbers from late medieval buildings, some of which had been of some status. The ridge and furrow appears to have been divided into narrow enclosures in 'strip form' respecting the curves often associated with this class of earthwork but with regular straight sections of hedgerow - especially in the north west of the area where the strip enclosures take on the characteristics of surveyed parliamentary enclosures. These enclosures (apparently outside the golf course in 1999), are associated on the 1855 OS with the former open field label 'Braithwaite Field'. These enclosures are shown as new allotments on the Brampton Bierley, Wath and Swinton enclosure award plan of 1816 (Bingley in Sheffield Archives NBC 58) Significant legibility of the earlier landscape types of this polygon survive well within this golf course - particularly the 'furlong' layout of the ridge and furrow and the fragmentary curving boundaries (which survive partially as lines of trees dividing the fairways), and the later 'surveyed' enclosures to the north west.
