The Victorian manor of Wood Norton is actually the gateway to a vast network of tunnels burrowing into the Worcestershire forest. The bunker was initially purchased by the BBC at the onset of World War II to serve as a hidden base for the broadcasting corporation in the event of a major crisis in London.

The Raven Rock Mountain Complex in Pennsylvania has maintained an aura of mystery since its construction began in 1948. The Pennsylvania complex first opened its doors in 1953.

It was built with the intent to be the "centre of a major emergency hub" and boasts a gigantic office space and a capacity for 1,400 people. The base also features two tunnels and 34-ton blast doors to reduce the impact of any bomb attack.

In the American Appalachians, Virginia, there's a base called Peters Mountain which currently serves as a communication station for the mobile phone operator AT&T.

These installations are essential for the US government's continuity plan. The centre in the Appalachians can accommodate a few hundred people. In the event of an attack on Washington, it could serve as a relocation site for intelligence agencies.

The Cheyenne Mountain Complex, located in El Paso County, Colorado, is a US Space Army defence bunker. It's also more commonly known as the headquarters of NORAD (North American Aerospace Defense Command) and the site was built in the 1950s in response to Cold War paranoia.

This extraordinary bunker includes five chambers, all equipped with fuel and water tanks - and in one section, there's even said to be an underground lake. In a crisis, the Cheyenne Mountain complex can accommodate up to 1,000 people per month.
