The Diefenbunker is a four-story, 300 room, 100,000 square foot underground bunker, and was meant to house 535 Canadian government officials and military officers in the event of a nuclear war. Shrouded in mystery, the Diefenbunker, nicknamed after then Prime Minister John Diefenbaker, was designed and built in secrecy during the crest of Cold War fear, between 1959 and 1961. The name of the facility was given by a Toronto Star journalist who exposed a story of its development.
