Diefenbunker: Canada's Cold War Museum

The Diefenbunker: Canada’s Cold War Museum, a once-top secret, four-storey underground bunker, is the only museum of its kind in Canada. 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 learning about our past — and helping us to understand the present. 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.
