The Largest Underground City in Every US State (And What They're Hiding)

The United States is hiding entire cities underground, and most people have no idea they're there. We all know the country has skylines, suburbs, and buzzing cities on the surface. But under every single state, there's an entire world that was built to exist out of sight. A bunker, a tunnel network, a repurposed mine, a subterranean mall... that shows just how much of this country was designed to function underground. In this video, we break down the biggest underground city in every US state, all 50 of them, and dig into what's hiding below street level. From a massive Kansas salt mine turned into a nuclear-proof storage vault to a Texas tunnel system connecting 95 city blocks without ever seeing daylight, this is the America that was built to stay hidden... and it's way bigger than you think. ► Delaware Has a Secret Nobody Talks About    • Delaware Has a Secret Nobody Talks About   ► The Deepest Cave in Every US State (And What's Hiding Inside)    • The Deepest Cave in Every US State (And Wh...   ► The Most Dangerous Geographic Place in Every State    • The Most Dangerous Geographic Place in Eve...   While we do our best to provide you with the most accurate information.
