City 40

In the secluded depths of Russia lies a seldom-seen Soviet city called Ozyorsk (Ozersk), nestled amidst barbed-wire fences under the watchful eye of armed guards. This enigmatic locale, found in Chelyabinsk Oblast, stands out as both one of Earth's most contaminated landscapes and a guardian to the world's largest stores of nuclear materials.
