The Secret Soviet Bunker Built 18 Floors Beneath Moscow for Nuclear War

Sixty-five meters beneath a quiet Moscow street, hidden under an ordinary-looking building, the Soviet Union carved out one of the most secret military command centers of the Cold War. Known today as Bunker-42, the Tagansky command point was designed to keep the Soviet leadership and its long-range bomber command alive and connected through a nuclear attack, a fortress of steel and concrete built for the day the bombs fell. In this deep-dive documentary we trace its full story: the atomic shock of 1945 that drove Stalin underground, the race to build the Soviet bomb, the American bombers and war plans that haunted the Kremlin, the metro engineers who dug the shaft in total secrecy, and the officers who stood watch far below the city on trains that ran only at night. We also explore the wider hidden world it belonged to, from the legendary Metro-2 tunnels and the rumored underground city at Ramenki to the mountain command posts that still exist today, and the mirror-image bunkers America built for the very same fear. This is the history of the underground fortress meant to survive the end of the world, the people who kept its secret for nearly forty years, and why the question it was built to answer still shapes the world we live in. If you enjoy Cold War history, Soviet history, and untold stories of secret military engineering, watch to the end, and subscribe for more deep-dive documentaries.
