The Rosenkrantz Tower, part of the Bergenhus Fortress by the harbour, is a 16th-century fortified residence and one of the most important Renaissance monuments in Norway, built on medieval foundations. Ticketed visitors can climb the winding stairs through the historic chambers and dungeons to the rooftop for fine views over the city and the Vagen. Combined with the neighbouring Hakon Hall, the tower offers a fascinating journey into Bergens medieval and royal history.
