This polygon covers part of the southern section of the Doncaster Sheffield airport, which was opened in 2004. It was opened on land that had been part of RAF Finningley. The RAF base was opened in 1936 in response to German re-armament. Expansion during World War 2 saw more runways added. In the mid 1950s the runway was further upgraded to accommodate Vulcan bombers. Nuclear weapons storage facilities were also added. The base became a training facility from the 1970s onwards, becoming famous for its air show. It closed as a military base in 1996. Prior to this it was part of the Finningley Park Hall estate. The origins of the park and estate are thought to lay in a medieval deer park. Hunter (1828, 79) refers to the park owned by Idonea de Vipont in Austerfield. The park pale (boundary) is marked on the 1st edition OS map of 1854. It is likely that this represents part of the boundary of the medieval deer park. Legibility of the former landscape is invisible.
