Diefenbunker: Canada's Cold War Museum

The Diefenbunker: Canada’s Cold War Museum is a four-storey Cold War bunker built to protect the government from a nuclear attack on Ottawa. Once top-secret, this underground facility is now open year-round. During Digital Doors Open, you can explore this site through a series of virtual tours, download some colouring pages from their collections, keep busy with various jigsaw puzzles, or play the online game, Project Rustic (Flash required). And learn more in the video below from Historica Canada about the Cold War and the important role that this site played.
