The Soviet Cities Built Underground to Survive Nuclear War... And What Remains Inside

Beneath the mountains and city streets of the Soviet Union, engineers built an entire hidden nation designed for a war that everyone hoped would never come. This is the story of the USSR's continuity-of-government program — the granite fortress of Yamantau Mountain, the redundant command post buried inside Kosvinsky Kamen, the secret Metro-2 tunnel network built beneath Moscow's public subway, and the nationwide Grazhdanskaya Oborona shelter mandate that quietly fortified tens of thousands of ordinary apartment basements. We break down the real engineering constraints — depth, EMP shielding, air filtration, water, power, and human psychology — that forced Soviet planners to construct a subterranean civilization capable of outlasting a nuclear war. And we trace what happened to that entire hidden network after the Soviet collapse, when some of it kept expanding even as the country ran out of money to pay its own soldiers.
