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 spark meaningful conversations, collaborations, and connections in response to our changing world.
