A Cold War-era bunker designed to save Soviet leaders from a nuclear blast has been turned into a venue for an 'end of the world' party tomorrow.
Bunker No. 42, which has been converted into a museum, is 56 metres below the ground in central Moscow near the Kremlin, and can fit up to 300 people.
A tour guide at the bunker, Alexei Pavlovsky, explained that the idea for the party came from visitors who were interested in marking the end of the Maya Long Count calendar - an event which has been interpreted by various groups as the end of days.
Pavlovsky told The Daily Telegraph: "Many people would feel much calmer if they could spend this critical day enjoying maximum comfort and safety. There'll be a children's room with cartoons; for adults, there'll be movies, talks dedicated to the end of the world and tours of the museum. There'll be live broadcasts from other bunkers in other countries."
Guests have been promised that they will see out the apocalypse in comfort, with regular updates about life on the surface, and a Wi-Fi connection.
And if you wish to imbibe during your last hours, there is even a VIP treatment package.
Anna, a student who visited the bunker on Wednesday said: "The bunker is rather big, but everything here is arranged in a way that makes people feel safe. This is a comfortable, cosy place to spend not just a day, but a whole war and even the end of the world."
Tickets are being sold at over $1,000 each - £600 - and to make up for the high price, the company has offered to return 50% of the ticket price if the Mayan's predictions for the apocalypse turns out to be a disappointment.
The bunker party isn't the only doomsday party happening in Russia - Chillax Hostels are offering travelers free night stays on the 21st and the 22nd.
The party will have themed decorations and contests, and include the arrival of costumed aliens who speak different languages.
A hotel on the slopes of Mount Rtanj in Serbia is also selling itself as the destination to survive the apocalypse - based on the mystical powers that locals say the mountain has, since the mountain swallowed a castle belonging to a wealthy sorcerer, trapping him inside.
