Diefenbunker: Canada’s Cold War Museum

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

The Diefenbunker offers visitors a unique experiential learning environment inside Canada’s most significant Cold War artifact, along with award-winning programs, events, exhibitions, and escape rooms.
