28. Mount Weather Emergency Operations Center, United States

Unless you are an apocalypse planner, a bunker is probably the last thing you are thinking about right now. In case an apocalypse was to happen, the government officials are going to be just fine. Mount Weather Emergency Center in Virginia is built to be the safest place in the world for any event. 

This bunker was built during the Cold War, and it was designed to protect government officials and the country's national treasures. Unless there is a necessary need for people to take shelter, the building is completely off-limits to every besides the FEMA employees that run it.
