Blackburn County Junior School and attached playing field are first depicted on the 1967 OS map. The area had been agricultural until this point apart from a small area of allotments towards the south of the polygon. The 1st edition OS map of 1855 shows a regular pattern of fields with straight boundaries which were probably created through the parliamentary enclosure of Middle Common by the Kimberworth award of 1800. Legibility of the former landscape is invisible.
