The testing of naval weapons station went into operation in 1939, is located 2,7 km from the coast and had long been exploited. The building is completely destroyed by her tumultuous waves of the troubled gray Caspian. Suffice it to say that the observation tower station located at a height of 42 meters above sea level, and in the storm before the tower reaches foamy waves curled.

All the underwater part of a giant pavilion, called “the masses”, was built on the coast in the pit with a capacity 530 thousand cubic meters, dug with the help of dredgers, (and sometimes by hand).

At the bottom of the pit was built a huge concrete “box” height of 14 meters, after which the artificial ligament, separating the basin from the sea, was destroyed, and surfaced “box” was towed to the construction site of the station in February 1935. There “box” filled with water and put on the prepared area of the quarry stone. Further construction of the station were built in the usual way to transport people and materials from ships.
