The Central Emergency Government Headquarters

Irreverently known as the "Diefenbunker," this structure became a powerful symbol of Canada's response to the Cold War. Designed in the 1950s to withstand all but a direct hit by a nuclear weapon, it was intended to shelter key political and military personnel during a nuclear attack. Although it never served that purpose, the Diefenbaker government made plans to retreat there during the Cuban missile crisis of 1962. The bunker functioned as the hub of a communications network and civil defence system until it closed in 1994.
