This polygon covers Armthorpe comprehensive school, Our Lady of Sorrows primary school and the extensive recreational and sporting facilities associated with them. The comprehensive school is first depicted on the 1931 OS map but is probably contemporary with the surrounding housing built for colliery workers at the nearby Markham Main which began production in 1924. Prior to this, the area was agricultural. The 1st edition OS map depicts a series of thin strip fields labelled as 'North Field', a probable former open town field. The strip fields resulted from consolidation of the furlongs of the open field over time. Legibility of the former character is, however, invisible.
