The Diefenbunker, Cold War Museum in Ontario Canada

Located in Carp, Ontario, this bunker was originally built in 1958 to house the Canadian prime minister and important members of the government in case of a nuclear attack. It is now a museum, meant to preserve Canada's role during the Cold War.

The Diefenbunker was named for the prime minister at the time, John Diefenbaker. It measures 100,000 square feet and the museum has guided and self guided tours. The restored rooms display the situation center, the Bank of Canada vault, living quarters and medical facilities. It is open daily from 10:30 a.m. to 4:00 pm. Free one hour tours are available between 11 and 2 and must be booked in advance. Admission is CAD 14 + HST for adults.
