It is the largest of the declassified bunkers nowadays. In the center of Samara, in the yard of an ordinary house, which are quite numerous not only in Samara, but in other cities as well, on the depth of 37 meters, an object that used to be secret one, is located. The object is unique by its characteristics, it was built in amazingly short period (in nine months only) and it surpasses all its international analogues: the depth of Hitler’s bunker is 16 meters, the ones of Churchill and Roosevelt are approximately 7 meters. In 1991 the object was declassified, opened for visitors and included into the list of places of interest in Samara. What is interesting, this monumental construction was never used for the purpose intended.
