The Diefenbunker is closed today, Tuesday December 12, due to the snow storm.  If you were planning a visit today, we are sorry for the inconvenience.  Please check back for updates.  We look forward to welcoming you to the Bunker soon!

Ottawa’s Most Unique Historical Site

The Diefenbunker is a four-story, 100,000 square foot underground bunker, built between 1959 and 1961. During the Cold War it was intended to house 535 Canadian government officials and military officers in the event of a nuclear war. It served as Canadian Forces Station Carp until 1994.

For years it protected us from 75 feet underground and we knew virtually nothing about it. Today, it operates as a not-for-profit, charitable museum and boasts award winning tours and programs.

Visit us to experience how close we came to a nuclear disaster. A lot has changed since 1961. There is no other museum like the Diefenbunker – we promise! Visit us for a tour!
