This Strange Russian City Was Kept So Secret It Didn’t Even Appear On The Map

It’s the mid-1940s, and a spate of disappearances is plaguing the Soviet Union. Citizens are vanishing from their homes, leaving their loved ones mystified. But these individuals aren’t just evaporating into thin air. No, they’re actually being taken deep into the Ural Mountains, to a place encircled by fences and armed checkpoints, somewhere so secret that it doesn’t even appear on the map. These citizens are being moved to “City 40” – and they won’t be allowed to leave.
