The Diefenbunker, Canada's underground bunker from the 1960s, was built in secrecy between 1959 and 1961 as part of Canada's contingency planning during the Cold War.
Despite its elaborate infrastructure designed to shelter key government and military personnel in the event of a nuclear strike, the facility was never used for its original purpose and was decommissioned in 1994.
Now serving as Canada's Cold War Museum, the Diefenbunker is a designated National Historic Site and subject of a photographic series by Brendan Burden, capturing its preserved interior.
The images showcase the austere yet compelling space of the Diefenbunker, reflecting the architectural intent and psychological weight of Cold War-era preparedness in modern history.
