Beyond natural caves, there exist mysterious tunnels postulated to be the work of ancient civilizations, their origins shrouded in secrecy.
A particularly intriguing case involved the 2003 discovery in Lake Bezdonnoe near Solnechnogorsk, where a life jacket belonging to sailor Sam Belovsky, missing since a terrorist attack on the destroyer “Cowell” in Yemen’s Aden port, was found. This enigma, considering the vast 3,000 km distance from the incident location, lends credence to the theory of subterranean routes connecting continents.
Another enigmatic site is the Marble Cave in Crimea, believed to be part of an extensive ancient tunnel network.
In the Volga region, researchers have uncovered a network of tunnels of various diameters converging at the Medveditsky ridge, indicating its pivotal role in an underground network.
Proponents of the artificial origin theory point to the tunnels’ melted walls as evidence of a high-tech anthropogenic origin, according to Tsargrad.
In the 1950s, a tunnel was constructed through the Tatar Strait in the Soviet Union, but declassified documents later revealed it was a reconstruction of an existing tunnel, its origins unknown. Within, mechanisms and fossilized animal remains were frequently discovered, only to mysteriously vanish.
Despite scientific advancements, many of Earth’s mysteries remain unsolved, with these underground tunnels being a prime example.
