The first military use of the area was in World War II, when a Starfish site was established at Hack Green.
The Hack Green Bunker was purchased by a private company and subsequently opened to the public in 1998 as a museum with a Cold War theme.
It also houses Ballistic Missile Early Warning System equipment originally from RAF High Wycombe.
Visitors can watch the BBC film The War Game, produced to inform the public of what would be likely to happen in a nuclear attack on Britain.
The band Everything Everything filmed the music video for their 2009 single "MY KZ, UR BF" inside Hack Green.
