The Naval Port of Karlskrona, which includes installations that illustrate its subsequent development up to the present day, is the best preserved and most complete of the surviving European naval cities. AuthenticityThe Naval Port of Karlskrona is authentic in terms of its location and setting, forms and designs, and materials and substances, as well as some of its uses and functions. In 2005, when Karlskrona became Sweden’s national marine port, its role as an active naval port was strengthened. The Naval Port of Karlskrona is included in the Blekinge Archipelago Biosphere Reserve (UNESCO Man and Biosphere Programme, declared in 2011). A management plan adopted in 2005 and revised in 2009 aims to preserve and develop the Naval Port of Karlskrona.
