Today Karljohansvern in Horten is a well-established, vibrant cultural centre which can be enjoyed by anyone wishing to visit it. In 1818, King Karl Johan decided that a new central Naval establishment should be built at Horten, with a naval shipyard and naval base. The Norwegian Navy and Armed Forces have developed over 200 years with pioneering technology, including steamships, ammunition, torpedoes and subsequently seaplanes. Karljohansvern has great military- and national historical importance. The Norwegian Armed Forces are still located at Karljohansvern and represented by a Commandant. The site is managed by the Norwegian Defence Estates Agency and Karljohansvern has become an important local centre for culture, businesses and experiences. The Fortress Manager is responsible for development work in conjunction with local cultural and business organisations and other joint venture partners.
