14. Mezhgorye, Bashkortostan
No matter how hard you try to get into the town of Mezhgorye, you won’t be able to. Located in the Republic of Bashkortostan, Russia – the town has a closed status. In administrative terms, this means that it’s subordinated directly to the federal government of Russia, which has restricted access to anyone except the town’s residents due to the secretive companies it has there creating underground facilities. It comes complete with a creepy looking entrance sign and is home to 17,000 inhabitants.
