In the middle of the Oslofjord, Oscarsborg Fortress sits enthroned on the small Kaholmen islands off Drøbak. An imposing 19th-century fortress complex that can only be reached by boat. Here, Norwegian artillerymen made history in 1940 when they sank the German cruiser „Blücher“, giving the Norwegian government crucial hours to flee Oslo.
