Looking at this photo you may exclaim "some bunker again!" Is there anything we haven't seen yet? But yes, there is. This one is in Moscow. It has a museum inside, but it's only the small part of the whole structure.
We have to go down for eighteen storeys! It means 60 m (197 ft) depth.
It is quite here, only sounds of trains can be heard in the distance.
From the moment of the bunker construction in the 1950s and till 1986 here used to be a command point of long-range aviation. In the times of "perestroika" they decided to repair it but didn't finish the works and abandoned it up to the 2000s when it was given to private hands.
