With December 21 - or 'the end of the world' as it is being referred to in some camps - fast approaching, Doomsday 'preppers' are putting the final touches to bunkers where they will ride out the Apocalypse.

The Mayan calendar has predicted that in just 38 days the world will end - but fear not, if you have so far been unprepared. 

Bunkers have already been built around the world to withstand impending doom and despite some rather shabby and gloomy interiors, they may soon be in high demand if predictions ring true.

America is dotted with bunkers - several working and others long out of use and turned into quirky museums and hotels.  

At the height of nuclear tensions with Cuba and the Soviets in the early Sixties, JFK built a bunker on Peanut Island, across from his family's Florida compound. It has now been turned into a museum. 

 

More luxurious options are also available. The Hilton Hotel in the Maldives offers underwater suites, with a view of marine life and where guests can wait out the apocalypse in the lap of luxury with a large comfortable bed and complimentary fruit baskets. 

The declassified bunker at Greenbrier, West Virginia has been turned into a four-star hotel, carved deep into a mountainside.

Preparing for the worst: Dixia Cheng is an entire underground city which exists below Beijing in China
