The Diefenbunker is one of the most unique National Historic Sites in Canada, and the country's most significant surviving Cold War site. Built to ensure continuity of government after a nuclear attack during the Cold War, this once-secret bunker was decommissioned in 1994 and re-opened as the Diefenbunker: Canada's Cold War Museum in 1998. The Bunker is located in Carp, 35 km west of Downtown Ottawa and attracts over 60,000 visitors a year. It is one of few Cold War bunkers in the world that the public can visit, attracting local, national and international visitors.
