Sites tied to alleged government secrecy, cover-ups, or classified research.
A windowless 550 foot Manhattan skyscraper identified through Edward Snowden's leaked documents as a major NSA mass surveillance hub hidden inside a working AT&T switching building.
A restricted U.S. Air Force facility in the Nevada desert, publicly acknowledged only in 2013, whose decades of classified aircraft testing fueled UFO lore amplified by Bob Lazar's 1989 claims about reverse-engineered alien technology.
A 2,700 acre private redwood retreat north of San Francisco where some of the country's most powerful men have gathered in secret for over a century, fueling decades of elite conspiracy theories.
Europe's particle physics laboratory and home to the Large Hadron Collider. Thanks to a gifted statue of the Hindu god Shiva and the sheer scale of its underground tunnels, it's also the target of internet theories claiming it opens interdimensional portals and causes the "Mandela Effect."
The primary airport serving Denver, Colorado, notable for its distinctive tented roof and a cluster of conspiracy theories alleging secret underground facilities and coded symbolism in its public artwork.
The underground base was invented, and the people who invented it worked for the U.S. Air Force. A counterintelligence officer at Kirtland fed forged documents to an Albuquerque businessman to steer his attention away from the base he was filming, and years later said so publicly.
A driver taking a break in a disused customs building at Canfranc found a stack of weathered papers, one of them stamped for a consignment of gold bars. The documents showed that around 86 tonnes of Nazi gold had crossed this platform between 1942 and 1943, on a route that appears in no other accounting of where the plundered gold went.
The United States' most heavily guarded gold vault, and the subject of a recurring theory that some or all of its gold has quietly disappeared.
A wooded Dutch hotel hosted an off-the-record 1954 gathering of European and American elites meant to ease Cold War tensions, and gave its name to an annual, invitation-only conference that has run for seven decades under a level of secrecy that still fuels theories of a shadow world government.
