CANADIAN WINTER WARNING NOTICE
Although the Diefenbunker was built to withstand a nuclear blast at the height of the Cold War, sudden winter storms and poor road conditions do occasionally force us to close our blast doors. Over the winter months, we encourage visitors to check our website or call the Museum in advance of any visit to confirm our hours. Thank you!
Ottawa’s Most Unique Historical Site
The Diefenbunker is a four-story, 300 room, 100,000 square foot underground bunker, and was meant to house 535 Canadian government officials and military officers in the event of a nuclear war. Shrouded in mystery, the Diefenbunker, nicknamed after then Prime Minister John Diefenbaker, was designed and built in secrecy during the crest of Cold War fear, between 1959 and 1961. The name of the facility was given by a Toronto Star journalist who exposed a story of its development. Want to know more? Visit us for a tour!

We’re looking for Volunteer Docents! The Diefenbunker is seeking history enthusiasts of all ages for the position of Volunteer Docent.

We are thrilled to announce that we received Ottawa Tourism’s Partnership of the Year at the 2014 Awards Gala; an award shared with the Haunted Walk Ottawa, the Bytown Museum and Ottawa Jail Hostel. During the Halloween season, the Haunted Walk offered three unique tour options with its partners, including our Incident at the Bunker: A Zombie Adventure. These hair raising tours attract new and younger audiences to our facilities and present heritage interpretation in an altogether new light.
Our thanks to the Haunted Walk for submitting the nomination and for working with us to offer these ghoulish tours.
We have our very own APP! It’s available through iTunes and Android downloads. It’s free to download and gives a full virtual tour of the closed machine room, audio tours and upcoming events. **Due to WIFI restraints, Diefenbunker visitors are encouraged to download the app offsite or before entering the facility.**
