After visiting the deserted wastelands of the Chernobyl nuclear accident site in the Ukraine, the Land Rover Journey Of Discovery expedition landed in an ominous former Soviet submarine base.

A relic of the Cold War era, the former Soviet Black Sea submarine base provided the Land Rover Discovery vehicles with a drive through the once top-secret hidden tunnels.

Plans to build a top-secret nuclear submarine base that would eventually become the operational home for the fearsome Soviet Black Sea Fleet was signed off by Joseph Stalin in 1953.

It took nine years to build the 15,300 square foot (1,421 sq meters) facility which was hidden inside the base of a mountain in the port town of Balaklava on Ukraine's Crimean coast.

With its entrance camouflaged from view from any spy plane, it could survive a direct nuclear hit and at maximum capacity could hold 3,000 people with supplies to sustain them for a month.
