17 Unusual Urban Legends Behind the World’s Most Iconic Landmarks

15. The Underground City Beneath the Kremlin (Russia)

The Kremlin, Russia’s seat of power, has long been associated with political intrigue, but its greatest mystery may lie beneath it. Known as “Metro-2”, this rumored underground city is said to contain hidden tunnels, secret bunkers, and a ghost railway built by Stalin. Some believe it was constructed as a last-resort escape route for Soviet leaders, while others think it hides classified military experiments or even lost treasures from the czarist era. What makes this legend particularly unsettling is the fact that urban explorers who have attempted to find Metro-2 often go missing. In 1994, a group of Moscow students claimed to have discovered a tunnel entrance, only to be warned away by unidentified men in military uniforms. Whether Metro-2 exists remains unconfirmed, but many believe the Kremlin holds more secrets than the world will ever know.
