Festung Norwegen (transl. Fortress Norway) was the extensive defense and fortification system constructed in Norway, part of the Atlantic Wall, after the conquest and occupation of Norway by Nazi Germany in World War II.[1] Some, including Reichskommissar Josef Terboven, thought that these fortifications would serve effectively as a last perimeter of defense of the Third Reich in the event of Allied victory on the continent. This led to German troops being diverted from mainland Europe, which resulted in a quicker end to the war.
