Digging Deep into the Cold War: Our Partnership with the Diefenbunker Museum

Just four years after it was decommissioned, the Diefenbunker reopened in 1998 as a museum dedicated to preserving and interpreting Canada’s Cold War history. Today, it continues to invite visitors underground to explore the complex legacy of that era.

Know History was proud to partner with the Diefenbunker to develop two new permanent exhibits:

• Between the Lines: Cold War Communications in Canada explores Canada’s crucial contributions to military and commercial communications technology during the Cold War.
• Whose Side? Propaganda and the Cold War examines how governments and grassroots movements used information—both true and false—to shape public perception and influence global opinion, a theme with undeniable resonance today.

Working closely with museum staff, our team led the planning, research, writing, copyright clearance, and exhibit development. Both exhibits officially opened to the public on June 27, 2025.
