About Canada’s Cold War Museum
The Diefenbunker is a massive four-storey underground bunker, built between 1959 and 1961. During the Cold War, top officials were to take shelter here in the event of a nuclear war. It was active as Canadian Forces Station Carp until 1994.
Today, it operates as a not-for-profit, charitable museum with award-winning tours and programs.

About the Cold War
The Cold War is the period between the end of the Second World War in 1945 and ends with the fall of the Berlin Wall in 1989, followed by the collapse of the Soviet Union in 1991. It was a period of tense conflict between the United States and the Soviet Union and each country’s respective allies.
