Mercury
Your judgment was correct! This next entry on our list also has to do with a nuclear site. Located in Nevada, the same as Area 51. Mercury is a closed village in Nye County, Nevada, United States. Why is a village forbidden to people you might ask? Well, the village was part of the shocking Nevada Test Site, so you wouldn’t want to get too close to it anyway. However, in principle it is possible to visit the Nevada Test Site, public tours do take place but only four times a year. But the village of Mercury itself is generally barred from people.
Ozersk
Also known as ‘The graveyard of the Earth’, Ozersk, is a secluded city in Russia and is located inside Chelyabinsk Oblast, Russia. Under the Soviet regime, it was only known as City-40 and the birthplace of the Soviet nuclear weapons program. For quite some time, residents were prohibited to leave the city, nor were they allowed to make contact with the outside world, so much so that their identities were even erased from the Soviet census. Very surprisingly, they were provided luxurious commodities that outshone any other cities in the country. Even today, it is out of bounds to visitors. With the radioactivity from the Mayak incident in the area, it is probably not the best idea to visit either.
