Mid way between Norway and the North pole lies the island of Spitzbergen.

At 81 degrees north it’s a very cold and remote place with 2,000 people and 3,000 polar bears. The treaty that ceded it to Norway in 1920 stipulated that all foreign ventures on the island could stay.

This enabled the Soviets to expand their mining operation and set up the town of Barentsburg, complete with statues of Lenin, as a strategic foothold on Norwegian soil.

It survives to this day and Eric Campbell braves close encounters with polar bears amid extraordinary scenery to investigate this bizarre relic of the cold war.
