Descend into history, 75 feet underground.

History. Education. Art. Find it all at the Diefenbunker, 75 feet underground.



We invite you descend into history. Let us show you how.


History, underground.

The Diefenbunker: Canada’s Cold War Museum is a once-top secret, four-storey underground bunker, originally designed as the centre for Canada’s defence against nuclear attack during the Cold War. Now, it is a one-of-a-kind museum and national historic site preserving and promoting Canada’s Cold War history.

When you visit the Diefenbunker, you are stepping into history — we are Canada’s most significant Cold War artifact and stand as a testament to the important role that Canada played during a critical period in recent world history. We have a crucial role to play in helping us to understand our past and build our collective future.

More than a museum, the Diefenbunker is a place where visitors can immerse themselves in the stories, people, and artifacts of the past, and take away lessons for the 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.
