The Diefenbunker is a four-story, 300 room, 100,000 square foot underground bunker that was meant to house 535 Canadian government officials and military officers in the event of a nuclear war.

Ottawa’s most unique historical site

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.
