Discover the Secrets of the Diefenbunker: The Ultimate Visitor’s Guide

Ottawa is a city that is home to many historic locations. Parliament Hill, Rideau Hall, and many more are just a few examples of this.

But none of them are quite like the Diefenbunker Cold War Museum. Imagine walking through 100,000 square feet of metal and concrete, and seeing all sorts of military equipment and government documents.

It makes you feel like you’ve traveled back to the 1950s when tensions between the world’s superpowers were high. It’s a truly remarkable place that you will want to experience for yourself. 

Now, allow me to give you a detailed guide to the Cold War Museum and the things that you will find as you explore the Diefenbunker. 

History of the Diefenbunker

History of the Diefenbunker

In the 1950s, the former Prime Minister of Canada, John Diefenbaker, commissioned the construction of a nuclear fallout shelter known as the Diefenbunker. 

Construction of the Diefenbunker began in 1959 and was completed in 1961. A small village called Carp, which was just outside of Ottawa, would be the site of construction for the bunker. 

The reason why Carp would be chosen as the site for the bunker would be its strategic location. The area was far enough from major urban centers to ensure its safety from potential nuclear strikes and minimize casualties. 

In official parlance, it was referred to as the “Central Emergency Government Headquarters,” and it was one of six shelters that were constructed in the event of a nuclear assault. 

To ensure the safety of government officials, the bunker was created using the most advanced technology at the time. 

Its nuclear roof would allow Canadian officials to operate safely underground for 30 days in order to assist with the governance and rebuilding of the country. 

When the Cold War tensions began to ease in the 1990s, the Diefenbunker was decommissioned in 1994, after it served for a grand total of 33 years. 

However, recognizing its historical and cultural significance, the facility was preserved and transformed into a museum, allowing visitors to explore its unique history and experience a glimpse into the fears and strategies of the Cold War era.

In addition to that, its significance to the country resulted in its designation as a National Historic Site of Canada.

Today, the Diefenbunker Museum serves as a fascinating testament to Canada’s preparedness during a tumultuous time in world history. 

Tourists can take guided tours that take them through the various rooms and corridors, showcasing the bunker’s original equipment and artifacts from the Cold War period. 

The museum provides an immersive educational experience, shedding light on the political climate, national security measures, and human stories associated with this intriguing underground facility.

In more recent times, the Diefenbunker has also been the setting for quite a number of movies. You may recognize titles such as “Sum of All Fears,” “Zygote,” and even the most recent “Fatman.” 

You also have one of the highlights of the exhibition, “Lost Nuke: The World’s First Broken Arrow.” It explores the story of the first nuclear weapon that was “lost” and features relics that were discovered at the crash site of the infamous airliner.

A ticket to the Diefenbunker costs $18.50 for adults and $17.00 for seniors. For younger visitors, it costs $14.00 for students 18 and above, $12.00 for youth ages 6-17, and children aged 5 and below are free.

There are two permanent exhibits in the Diefenbunker that are available for public viewing. These are the “Canada and the Cold War” and “An Inuit Story: The DEW Line” exhibits. 

The former goes into detail about the events that transpired in Canada during the Cold War. Meanwhile, the latter describes how the Inuit and indigenous groups inhabiting the Arctic were affected by the Distant Early Warning (DEW) line. 

Canada and the Cold War

Canada and the Cold War

The Canada and the Cold War exhibition will take you through key stages in Canada’s Cold War history, examining how community and government responses at the time shaped our country into what it is today.

To many, the Cold War still remains one of the most influential events in human history, one in which Canada participated. 

It was a harsh and chilly struggle between the world’s superpowers. While the countries were technically at peace, this period was characterized by an aggressive arms race, several proxy wars, and ideological bids for world dominance.

Canada offered troops as well as technological breakthroughs for the military and its peacekeeping mission to prevent things from escalating further. The threat of nuclear war was apparent at home, and it struck ordinary Canadians as both real and terrifying.

The exhibition follows a timeline of events from the mid-to-late 1900s to the present day to provide a comprehensive view of Canada and Canadians’ roles in the Cold War. This chronological timeline begins in the year 1900. 

Canada and the Cold War explores themes of achievement and tension, preparedness and fear, and Canadian identity both at home and abroad. 

It also follows the doomsday clock, which slowly marches down to midnight. The exhibition serves as a chilling reminder of how close the world came to a global nuclear disaster.

This newly updated exhibition includes enthralling narratives from Inuit and other diverse perspectives, as well as compelling audio and video content and interactive activities for visitors of all ages. 

The exhibits are drawn from the Diefenbunker’s substantial holdings. They consist of five exhibition chambers that served as sleeping quarters for military personnel during the Diefenbunker’s active period.

With that being said, “Canada and the Cold War” makes us think about what we can learn from current occurrences in terms of life lessons. All the compiled artifacts and history help us prevent another incident like this from happening again. 

An Inuit Story: The DEW Line

An Inuit Story The DEW Line

An Inuit Story: The DEW Line reveals the long-term harmful impacts of the Distant Early Warning (DEW) Line on Inuit villages in the Arctic, ranging from forced relocations to toxic waste.

Between 1955 and 1957, the US and Canadian militaries built an Arctic radar network to identify enemy bombers. It was known as the DEW Line or Distant Early Warning System. 

While the DEW Line’s construction, operation, and subsequent abandonment continue to have an impact on Canada’s North, the Inuit have increasingly taken charge of their own future.

You will be able to witness firsthand accounts and stories from Inuit people affected by the DEW Line in this exhibition. Learn from Canada’s Cold War past to see how you can contribute to Canada’s reconciliation with the Inuit. 

This exhibition was created in conjunction with the Government of Nunavut and is available in English, French, and Inuktitut to accommodate different audiences. 

It features oral histories and written testimonials from members of the Inuit community in an entire gallery dedicated to Inuit voices and experiences. 

To add to that, it has dramatic visuals and films, an interactive exercise, and a large-scale floor map of Canada’s North to further enhance your experience.
