CERN
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."
Field Guide Entry
CERN, the European Organization for Nuclear Research, was founded in 1954 by twelve member states as one of Europe's first major joint scientific institutions; it now operates the Large Hadron Collider, a 27-kilometer particle accelerator buried beneath the France-Switzerland border that led to the 2012 discovery of the Higgs boson. In 2004, the Government of India gifted CERN a two-meter bronze statue of Shiva Nataraja, the "cosmic dancer" form symbolizing creation and destruction, commemorating India's decades-long scientific collaboration with the lab.
Online theories circulating heavily on social media claim the Large Hadron Collider opens portals or wormholes to other dimensions, or even "Hell," sometimes pointing to the Shiva statue's creation-and-destruction symbolism as supposed corroborating evidence. A related, widely shared theory holds that each time the LHC runs, it shifts people into a slightly different parallel timeline, supposedly explaining the "Mandela Effect," the phenomenon of large groups sharing the same false memory.
CERN physicists have publicly and repeatedly rejected the portal and dimension-shifting claims as having no basis in the lab's actual research. Mainstream psychologists attribute the Mandela Effect itself to ordinary memory fallibility, confabulation and source confusion that happens at the scale of the internet, and note that documented false-memory phenomena predate the LHC's 2008 startup by decades; the term "Mandela Effect" itself wasn't even coined until around 2010, undermining any causal link to a machine that was already running by then.
Visiting Information
The statue stands near CERN's Main Building on the Meyrin site. The free exhibitions at Science Gateway do not include it, and neither of the two guided tours open to individual visitors, the synchrocyclotron and the ATLAS control room, is described as stopping there. CERN Science Gateway is free and open Tuesday through Sunday from 9am to 5pm, and registering online guarantees entry to the exhibitions. Guided tours are reserved on site on the day, first come, first served, and CERN says only about 10 percent of Science Gateway visitors get a place.

Estación Internacional de Canfranc
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 metric tons 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.
Fort Knox
The United States Bullion Depository, completed in December 1936, has been opened to outside visitors only a handful of times, most notably for a 1974 congressional and press tour meant to quiet rumors that the gold was gone. It reports holding more than 147 million troy ounces.
33 Thomas Street (Titanpointe)
A windowless, 550-foot AT&T switching building in Manhattan. In 2016, The Intercept reported, drawing on Edward Snowden's leaked documents, that it appears to house a major NSA surveillance hub.
Allan Memorial Institute
In January 1973, on the order of CIA Director Richard Helms, the agency destroyed the bulk of its MKULTRA records. Records that survived tied the CIA to Dr. Ewen Cameron's "depatterning" experiments in this Mount Royal mansion, which the agency paid for in part from 1957 through a front called the Society for the Investigation of Human Ecology. On July 31, 2025, a Quebec judge authorized former patients and their families to sue Canada, McGill University, and the Royal Victoria Hospital as a class.
