7Mezhgorye
Mezhgorye is a town in the Republic of Bashkortostan, Russia. This town forbids the entry of visitors and even Russians from other parts of the country. Rumours suggest that residents of this town are working on a top-secret project around Mount Yamantaw. This particular mountain is perhaps the location of a large number of Russian secrets like the nuclear program, bunker used during the war or a huge warehouse of coal.
