Entrance to the desolated docks when formerly the Soviet submarines were repaired. They look like a lot of branched corridors and rooms with the walls of concrete, and also the dock where submarines used to enter. Everything was built under a mountain, and there are another 200 meters of rock above.
The same corridor. On the wall it's possible to see a reflection of a very powerful lantern we took with us.
This is the dock. It's very dark, but it's possible to see something here. To the right there is a walk the personell is used to get around. To the left there is water, the place were a submarine entered, the gate was closed, the water pumped out, and reparations begun.
