This town has a population of 17,353 inhabitants according to the latest 2010 census. It is one of the most interesting towns of this type for sure.

A massive underground facility is said to exist in the Ural Mountains on Yamantau Mountain, near the city of Mezhgorye. Though the actual size of the facility is unknown, it is rumored to span more than 400 square miles.
