Video: Mayan apocalypse: Russian bunker preparing for end of the world on December 21 With the end of the world just a few days away, it may be the right time to plan a party. And if a house party sounds too risky, then a bunker based deep underground might prove the safest place to be when an apocalypse hailed by 'Doomsday' believers hits on December 21. Built in 1956 and transformed into a museum in 2006, the nuclear protective Bunker 42 in Moscow is offering £600 tickets for the underground party that will start late on December 20 and last until a day after the end of the world (December 22). As the museum's guide Alexei Pavlovsky explains, the idea to organise this type of event in the Bunker came from random museum visitors, so they just couldn't say no. The idea is pretty simple, many people would feel much calmer if they could spend this critical day being surrounded with maximum comfort and safety. And who are we to say no when we have 56 meters of ground above us and a well 100 meters below us, there's also a pumping system and ventilation. "On December 21 people will be able to spend the entire 24 hours from midnight to midnight here underground," added Mr Pavlovsky. According to some modern-day interpretations of the Mayan calendar, December 21 marks the end of a cycle in the calendar and the beginning of a new era for the world.
