This polygon covers the sports ground and recreational facilities of the Miners Welfare Ground at Armthorpe. The mine began production in 1924 and the facilities probably date from this period also. The park has expanded over time with the 1931 OS map depicting only the bowling green and tennis court. Prior to the welfare ground, the area was agricultural consisting of small fields with regular and straight boundaries. The fields were probably created upon the enclosure of the village green or common by the Armthorpe parliamentary enclosure award in 1774. Legibility of the former character is invisible.
