Diefenbunker - Canada's Cold War Museum

The Diefenbunker , formerly known by its military designation, Canadian Forces Station Carp (CFS Carp) , is a large underground four-storey reinforced concrete bunker and nuclear fallout shelter located in the rural area of Carp, Ontario approximately 30 km (19 mi) west of downtown Ottawa . Between 1957 and 1961, during the Cold War the Government of Canada led by then Prime Minister John Diefenbaker authorized the Diefenbunker to be designed and built as the Central Emergency Government Headquarters (CEGHQ Carp) in an attempt to ensure the continuity of government subsequent to a nuclear weapons attack by the Soviet Union . In 1994, CFS Carp was decommissioned and closed. In 1994, the Diefenbunker was designated a National Historic Site of Canada because it is considered the most important surviving Cold War site in Canada. The bunker is important as an engineering achievement and to the critical path method of planning used in its construction. In addition, the Diefenbunker is symbolic of the Cold War, a strategy of nuclear deterrence and the Canadian people's determination to survive as a nation following a nuclear war. The Historic Sites and Monuments Board of Canada (HSMBC) plaque located at the Diefenbunker states: In 1998, the facility was re-opened as a museum called the " Diefenbunker: Canada's Cold War Museum " allowing the general public year-round access to tour the facility.
