This polygon represents the majority of the municipal Longley Park, created from land set aside from residential development during the urbanisation of northern Sheffield by the Sheffield Corporation. Other parts of the park with differing landscape histories are separately polygonised as HSY 1143, 1144, and 1145. The following is based on a detailed study of the Heritage value of the park by Joan Sewell (Sewell 2004) for Sheffield City Council's Parks and Woodlands service. Fairbanks 1784 survey of the area depicts the surrounding countryside as a mosaic of early piecemeal enclosure fields, the names of many of which include the component 'Royd' which denotes woodland clearance and often relates to poorly drained land (ibid, 13) - 3 fields also include the component 'clay' in the title. Character units 1142, 1143, 1144 (parts of the park) and 1146 (now residential) all represent the former estate connected to the former Crowder House (demolished c.1950). This property which dated back to at least the 14th century was purchased in 1859 by solicitor Bernard Wake (ibid, 19), who converted the grounds to parkland by enhancing existing planting on the lines of earlier field boundaries with specimen trees. Wake's scheme is largely preserved within the present park and had the effect of preserving fragments of ridge and furrow within this area. Significant legibility of earlier landscape forms and features.
