Diefenbunker — Musée canadien de la Guerre Froide

Visiting the Diefenbunker is like stepping back in time 23 metres underground. Built in secret during the Cold War to house the Canadian government in the event of nuclear war, and designated a National Historic Site in 1994, this unique museum now offers exhibitions, guided tours, escape games, programs and events that invite visitors of all ages to explore this important piece of Canadian history.
