Balaclava Submarine Base

This Soviet submarine base could withstand a direct hit from a bomb ten times more powerful, than what the Americans dropped on Hiroshima and Nagasaki. Built within the cliff of Balaclava bay, this base is totally secluded and now serves as a museum and a relic of the old realities. This video shows a boat trip through the main water channel of the base. I hope the music copyright holders won't block this, I just couldn't resist it.
