This polygon covers Armthorpe Methodist Church. It is first depicted on the 1931 OS map but is contemporary with the surrounding housing built for colliery workers at the nearby Markham Main and appears to be an integral part of the estate design. 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.
