Playing fields attached to Acres primary school, which is also contained within the polygon. The school and playing fields are first depicted on the 1968 6 inch OS map. The eastern side of the polygon is the site of Manor Farm, shown on the 1923 25 inch OS map and the 1948 6 inch OS map. Prior to this the area displayed the characteristics of enclosed strip fields, probably enclosed from the Darnall town field called the 'Parke Field'. The Scurfield (1986) reconstruction of Harrison's survey of 1637 shows the western part of the area labelled as 'Acre Hill' and the eastern area as 'Black Edge Close'.
