Inside doomsday bunker complex the size of city
The bunker field is almost as big as New York's Manhattan neighbourhood - and has been described as a "backup for mankind"
A huge doomsday bunker complex the size of a city could save 10,000 people from a nuclear war, a deadly virus or an asteroid strike, its makers claim.
Hundreds of concrete military bunkers in South Dakota, US, are being transformed into a survival shelter in case of the apocalypse.
Vivos, a company that builds underground shelters to withstand future disasters, is repurposing the 18 square mile former military base.
It is three-quarters the size of Manhattan, New York, and access to the bunkers is through a huge heavy door.
The structures look bland from the outside - but once inside they appear to be designed like cosy front rooms.
There are sofas, cushions, a coffee table as well as paintings hanging on the walls.
In a video showing off one of the bunkers, a member of Vivos described the building as a "backup for mankind".
He says: "To not have this and to have a back up plan for mankind to have an insurance policy is crazy.
"At the cost we're able to do this - $25,000 per bunker its nothing, so it's crazy not to.
"It's nothing more than life assurance."
He goes on to explain how huge the bunker is 2300 sqft and says there are 575 bunkers in phase one of the transformation.Read More...
