A military bunker located near Corsham, Wiltshire, United Kingdom. This structure is situated in an area known for its extensive Cold War-era underground facilities, including the former Burlington Bunker (also known as Site 3 or Hawthorn Central Government War Headquarters). The region around Corsham was strategically important during the Cold War period, with numerous underground installations built to house government operations and military personnel in the event of nuclear conflict.
The area's limestone geology made it ideal for constructing large-scale subterranean facilities.
