Karlskrona annually hosts a maritime festival, which is one of the oldest „sisters“ of Rostock’s international maritime festival „Hanse Sail“. The city has many attractions which are granted the World Heritage title by UNESCO.
One example is the Friedrich Church, located on the Stortorget Square dating back to the 18th century. The construction of this church started in 1720. If you are interested in maritime history, visit the Maritime Museum. In June 2014 the newest attraction of the museum, the submarine hall, was opened. Other focuses of the city economy are software development and electrical engineering.
