9. Area 51 Military Base
Area 51 is located in the southern portion of Nevada and it’s the cover-name for a US military airfield. The base’s current primary purpose is publicly unknown; however, based on historical evidence, it most likely supports development and testing of experimental aircraft and weapons systems. The intense secrecy surrounding the base has made it the frequent subject of conspiracy theories and it is believed to be a hiding place for the most famous UFOs that Americans ever heard about. Needless to say that this is a military object and civilians are not allowed here.
