The Diefenbunker: Canada’s Cold War Museum, a once-top secret, four-storey underground bunker, is the only one of its kind in Canada and, arguably, in the world. Designed sixty years ago as the centre for Canada’s defence against nuclear attack, the museum and its stories have a crucial role to play in understanding our past — and our collective future. The Diefenbunker’s one-of-a-kind experiential learning environment, coupled with its award-winning programs, events, and exhibitions, draws visitors from around the world.

The Diefenbunker offers an 8-language audio guide, guided tours, birthdays, spy camp, and the Escape Room.

Fun Facts

  1. Even if the power goes out here in the bunker these rotary phones can be used! Many home phones during the Cold War just needed a phone line connection.
  2. In North America, only 1.5% of the population had home fallout shelters. This is well below what pop culture told us at the time
  3. The most powerful air raid siren built for the Cold War was 12 feet long, used a 180 horse power engine and could turn fog into rain.
