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!

In celebration of Canada’s 150th Anniversary, the “From Hand to Hand” photo series has also been made into a 2017 calendar which is now available through the Diefenbunker’s Cold War Store.

The Diefenbunker is delighted to welcome Hull based filmmaker, Pixie Cram, as the Museum’s 2017 Artist-in-Residence. Pixie will spend the next few months discovering and researching the Diefenbunker to create a short film which will premiere at the Museum later this year. More details…

Our toilets are pooped, and NEED YOUR HELP!
Every detail of this 100,000 square foot underground facility was carefully designed, including its truly remarkable toilets. That’s right – its toilets. The Diefenbunker’s historic toilets are mounted on a one-inch thick, hard rubber pads and have flexible connections to the main system so they can’t break or disconnect in case of an explosion (insert potty humour here).
