While your parents may have told you that the world is your oyster, some places on Earth will always be closed off to the public. From deserted islands to high-grade weapons factories, the countries in charge of these little-known places intend to keep it that way.

Dulce Base has long been rumored to be home to extraterrestrials. Found underneath the Archuleta Mesa in Dulce, New Mexico, conspiracy theorists believe Dulce Base is an alleged military base for both humans and aliens.
This theory started in 1979 when Albuquerque businessman Paul Bennewitz claimed he had intercepted electronic communications from an alien spacecraft. Ever since thrill seekers and U.F.O. enthusiasts have flocked to catch a glimpse of the site, and tourist numbers spiked when it the location was featured on the History Channel show UFO Hunters.
