Diefenbunker: Canada's Cold War Museum

Welcome to the Diefenbunker: Canada's Cold War Museum & National Historic Site!

This four-story, 300 room, 100,000 square foot underground bunker was meant to house 535 Canadian government officials and military officers in the event of a nuclear war. Shrouded in mystery, the Diefenbunker, nicknamed after then Prime Minister John Diefenbaker, was designed and built in secrecy during the crest of Cold War fear, between 1959 and 1961.

With its extraordinary engineering and architectural features, the Diefenbunker: Canada’s Cold War Museum is a poignant reminder of one of the most turbulent periods of modern history.

The blast doors open to the public from 11:00am - 4:00pm, 7 days a week.
