Oil stones
Perhaps one of the most amazing monuments of a bygone era. The settlement on stilts "Oil stones" was built in the east of Azerbaijan in 1949. This is a completely autonomous settlement, with all the necessary infrastructure for the people. Now there is no oil production, of course, but about 2 thousand people continue to call "Oil Stones" their home.
Station for studying the ionosphere
Engineers of the Soviet Union have developed a station for the drawings of the American project HAARP, located in Alaska. But our complex was truly Russian - the diameter of one parabolic antenna was as much as 25 meters. However, the station suffered a sad fate. In the mid-1980s, with the beginning of perestroika, publicity and general democratization, the study of the ionosphere took a back seat. After the collapse of the USSR, the station territorially relocated to the new state, Ukraine. While figuring out what's what, most of the equipment the locals simply dragged into precious metals.
Complex Proton
You hardly know that the Soviet Union was trying to build its own hadronic collider before it became fashionable. In 1983, the construction of the Proton Research Institute in Protvino was nearing completion: at the depth of 60 meters, even the main ring of the Soviet collider, whose length exceeds 21 kilometers, was laid. Unfortunately, the dawn of perestroika caught the country of the Soviets by surprise and in the confusion the government was not up to some kind of physics.
Submarine base
In Soviet times this place was designated on secret maps only as "object 825 GTS". It was here, near the Balaclava submarine base. The facility was built in 1961, as part of the program to strengthen the country's anti-nuclear defense. It is possible to get inside only through an adit or from the northern part of Tavros mountain, both doors being carefully camouflaged and waterproof. The territory of the base occupied an entire 5100 square meters: its own hospital, its own bakery and even its sports center. In case of an attack on the country of a potential adversary, the entire population of Balaklava could easily be located on the base, and the supplies would last for three whole years.
Station Chernobyl-2
In 1985, a monumental over-the-horizon radar "Duga" was built. This facility was required to detect possible launches of intercontinental ballistic missiles. The antennas rise 150 meters high, and the entire area of the complex is as much as 160 kilometers. After the accident at the Chernobyl nuclear power plant, the station had to be abandoned and today the facility called "Chernobyl-2" remains just a bait for brave tourists.
