Welcome to the Diefenbunker, Canada's Cold War Museum

Built to protect the government from nuclear attack, this once-secret bunker is now a museum and National Historic Site of Canada.

In addition to preserving and promoting Canada's Cold War history, we offer a variety of visitor programs and services. You can learn, play or shop as you discover the bunker’s secrets and relive the experience of the Cold War.

Our new Audio/Video self-guided tour is now available in addition to our guided tours offered hourly. (see our schedule here)

If you have any questions, please call 1-800-409-1965 or email us at info@diefenbunker.ca
