Ottawa’s immersive history destination.

The Diefenbunker is Canada’s most significant surviving Cold War artifact — it is an impressive four-storey underground facility that operated as the country’s central communications headquarters during the Cold War, ready at any moment in case of a nuclear attack. Today, it is a one-of-a-kind museum and national historic site, telling stories of national and international importance.

Through award-winning exhibitions, tours, programs, events, and escape rooms, the museum offers an important platform to spark meaningful conversations, collaborations, and connections in response to our changing world. Located in Canada’s capital, the Diefenbunker is preserving important Canadian Cold War stories and artifacts, and welcoming visitors from all around the world.

Descend into history, 75 feet underground, and immerse yourself in stories from the past. Explore educational exhibitions, connect with Cold War history, and discover unforgettable experiences.
