It had been built since 1957 until 1961 by military men, who were later accompanied by specialists in underground construction. It is also an anti-radiation shelter for 3000 people. The maximum width of the rocky ground is 126 meters. The channel has a length of 505 meters, a width of 6-8.5 meters and a depth of 6-8.5 meters.
