Welcome To Diefenbunker, Canada's Cold War Museum

Built to protect the government from nuclear attack, this once-secret bunker is now a museum and National Historic Site of Canada.

In addition to preserving and promoting Canada's Cold War history, we offer a variety of visitor programs and services. This year is our 10th anniversary — a perfect chance to visit us and relive the experience of the Cold War!
