We made an early morning visit to the Fjell Fortress. It is an impressive underground military base, with a labyrinth of around a kilometer of roads, 10 meters under Fjedla Mountain. The German military established the underground complex around its main artillery – the enormous triple-cannon. To mount the main gun turret at the fortress, it was necessary to dig 17 meters vertically into the mountain. The work was mainly carried out by prisoners from Eastern Europe. Fjell Fortress just outside Bergen was the biggest German fortress in Norway during the Second World War.
