Source : WIKIMEDIA COMMONS
Owned by the Holy See, the Vatican Secret Archives—now officially called the Vatican Apostolic Archives—house centuries of church history and confidential documents in one of the world’s largest archival collections. The archives are strictly off-limits to the public. Only researchers who pass rigorous vetting are granted access. Journalists, students, and amateur historians are entirely prohibited. Even for approved scholars, access is limited by special permits that must be renewed every six months.
This intense secrecy has fueled countless conspiracy theories, with some believing the Vatican hides humanity’s unknown truths within its walls. Regardless of speculation, curiosity about this Restricted Area continues to captivate the world.

Located in Nevada’s desert, Area 51 is a top-secret U.S. Air Force base whose existence was denied by the government for decades. In reality, the base is used for advanced military aircraft testing, but rumors of UFOs and alien life have never ceased.
Warning signs around the perimeter declare that deadly force is authorized against trespassers. There are no visible fences, but underground sensors and surveillance cameras blanket the area. Armed security forces respond immediately to any intruders. To safeguard national secrets, Area 51 remains one of the most heavily secured Restricted Areas on Earth.
