Grumant: A Lost Soviet Outpost in the High Arctic
Above Svalbard's Isfjorden, the ruins of Grumant mark a Russian and Soviet coal town that was evacuated in the war, shelled, rebuilt, and abandoned for good in the 1960s.

Above Svalbard's Isfjorden, the ruins of Grumant mark a Russian and Soviet coal town that was evacuated in the war, shelled, rebuilt, and abandoned for good in the 1960s.

On the shore of Isfjorden, Colesbukta was the shipping end of a Soviet coal chain, and its ruins, a cabin museum and a lonely cemetery are still there.

Founded by Swedes in 1910 and sold to the Soviet Union in 1927, Pyramiden was a showcase mining town on Spitsbergen with more than a thousand residents. Mining ended on 31 March 1998, the people left within months, and the cold has kept the town almost as they left it.

In February 1943, nine Norwegian saboteurs descended a frozen gorge, crept into the Vemork plant and destroyed its heavy water cells without firing a shot. Here is the full story of the raid, the escape to Sweden, and what really happened next.

Built in 1911 as the world's largest power station, Vemork later became the only industrial source of heavy water in occupied Europe. This guide follows its story from fertiliser works to wartime target to museum, with visiting details for today.
