The Bergenhus Fortress, guarding the entrance to the harbour, is one of Norways oldest and best-preserved castles, encompassing the medieval Hakon Hall and the 16th-century Rosenkrantz Tower. Set in grassy grounds by the water, the fortress recalls Bergens era as a royal capital. Exploring the historic buildings and ramparts, with the Rosenkrantz Tower rising above the harbour, offers a journey into the medieval history of the city and fine views over the Vagen.
