9. Area 51
Area 51, also known as Groom Lake, is a top secret military base and airfield located in southern Nevada. It has been a site for experimental aircraft and weapons testing, but no civilian is permitted to really know what goes on there. The CAI refuses to disclose any details about it, which has lead to many a conspiracy theory about Area 51. Of course, the most famous one is that they’re hiding crashed alien spaceships or working on energy weapons. Whatever is going on there, you’ll probably never get close enough to find out. The entrance to the zone says they can use deadly force if unauthorized people try to trespass.
10. Vatican Secret Archives
Well, the Vatican’s Archives may not be so secret anymore, but you won’t get to peruse them unless, of course, you plan to become Pope (and that’s probably not likely to happen). While the public can request to see any document that is older than 75 years of age, they cannot visit the archives, which are known to be vast and contain many historically important documents like Henry VIIIs request for an annulment to his first wife.
