However, it is not necessary to travel so far from home if you are filthy rich and you see an apocalyptic future, because a California-based company known as The Vivos Group, is already building deep underground shelters, strong enough to survive future catastrophes and disasters, in various places. The South Dakota underground village is made up of 575 military bunkers, which were originally built by the Army Corps of Engineers in 1942, as a military fortress, which has been repurposed. About 10,000 people should be able to live in the underground village once completed.
Deep down under London, there is a nuclear-proof shelter standing at the ready in case of war. The prime minister and Britain's military leaders can gain access to the bunker, which lies deep beneath the Ministry of Defence, Whitehall. Photographs taken of the Pindar facility in 2008 show stockpiling of such items as toothpaste, toothbrushes, and mouthwashes.

Meanwhile, Sweden, operating in a more egalitarian manner, has about 65,000 bunkers, which will fit seven million people of the almost ten million population, in the event of war. Sweden's shelters can be identified by a sign showing a blue triangle in an orange square, with the word "skyddsrum." Switzerland, however, has enough nuclear fallout shelters to accommodate its entire population.
