Diefenbunker: Canada's Cold War Museum
A former Cold War emergency-government bunker in Carp now houses the Diefenbunker museum. Its underground rooms preserve the spatial logic of civil-defence planning far from downtown Ottawa.
Why go
Heavy doors, long corridors, and command rooms convey the scale of preparations for a nuclear emergency. This is a distinct historical encounter from Ottawa's ceremonial monuments above ground. Moving through the original spaces explains the government's Cold War response more directly than a conventional display case could.
What to look for
Underground command and communications rooms
Long corridors and controlled access points
Useful to know
Treat Carp as a dedicated excursion and book ahead when the current visit format requires it.
