This weekend is Open Doors Ottawa, and we went to visit the Central Emergency Government Headquarters; a Cold War relic from the late 1950s and early 1960s. This was also known as Canadian Forces Station, Carp and is now known as the Diefenbunker, after the Prime Minister that established the facility. It was decommissioned in 1994 and now houses a Cold War museum.
This top-secret installation was meant to house key members of the goverment, senior civil servants and military personal in case of a nuclear attack on Canada (located between the USA and the USSR, there was a good chance that nuclear arms would cross Canada in the event of a nuclear war). The complex was designed to house 535 people for a month after a nuclear attack. It was designed to withstand the heat, shock waves and radiation from a blast as close as 1.6km / 1 mile away.
Back in those days, the Distant Early Warning (DEW) radar stations were thought to give three hours of warning of imminent nuclear attack. The key officials would be marshalled at the main train station, not far from the Parliament Buildings and moved by train to the complex. Canada was a gold reserve system nation at the time and the Bank of Canada had a large vault to house 800 tons of gold bars there. The Canadian government and the Canadian Broadcasting Corporation established an emergency broadcast system that would be able to control all CBC radio stations and broadcast to the people of Canada in an emergency situation.
The facility had medical facilities, eating, sleeping and work areas.
This image is the nuclear blast tunnel that was also the entrance to the complex. It is 115m / 378ft long and the complex entrance is at right angles to where I took this image. Huge steel blast doors prevent damage to the complex.
Needless to say, there were hundreds of people visiting while we were there. I shot everything with my f/2.8 14 - 14mm lens. It nicely allowed me to step in front of the people and made it look like I had the place all to myself...
