A beautiful, historic steamer that still sails in the Flensburg Fjord... if you're lucky, the ship will be in the harbor as you walk past

The paddle steamer Alexandra is a vibrant maritime landmark in Flensburg's historic harbor and is the last remaining sailing paddle steamer in Germany. Anchored directly in the museum harbor, the ship uniquely combines history, technology, and experience. The Alexandra was built in 1908 at the Janssen & Schmilinsky shipyard in Hamburg and named after Princess Alexandra of Schleswig-Holstein-Sonderburg-Glücksburg. From its inception, it operated on a regular service on the Flensburg Fjord. For decades, it also served as a patrol boat during the First World War, as a regatta support vessel at the 1936 Olympic Games in Kiel, and as a pilot boat, refugee vessel, and rescue ship during and after the Second World War. After the war, the Alexandra returned to civilian scheduled service in 1946, primarily on the Flensburg–Glücksburg route, and was finally decommissioned in 1975. After being decommissioned, she fell into disrepair in the harbor until 1979, when dedicated citizens formed the "Save the Alexandra" association and restored the ship. Thanks to their efforts, the Alexandra was seaworthy again in 1989 and was recognized as a cultural monument in 1990. Today, the Alexandra is a popular excursion option from May to September. She offers passenger trips on the Kiel Fjord – for example, to the Oxen Islands – and is the star attraction at harbor festivals such as the Rum Regatta or the Steam Festival. With its modern, preserved technology from 1908 – including a coal-fired steam engine – she is the only coastal vessel of her type in the world still permitted to operate.

The Flensburg Fjord (Danish: Flensborg Fjord) is an approximately 40 to 50-kilometer-long inlet of the western Baltic Sea and forms the border between Germany (Schleswig-Holstein) and Denmark along its northern and southern sides. Geologically, it was formed by the indentation of a glacial tongue in the inland ice during the Weichselian glaciation. It is classified as a fjord rather than a fjord because its flanks are relatively low. The fjord is divided into two sections: the inner fjord toward Flensburg and the outer fjord, separated by the Holnis peninsula. At its western end, in Flensburg, it flows inland—the westernmost point of the Baltic Sea also lies along this line. Today, the region is an important sporting area, especially for sailors, and hosts major regattas such as the Flensburg Fjord Regatta and the Rum Regatta. Fjord Week, with events for classic yachts, is also part of the regular schedule. The Flensburg Fjord is also attractive for its landscape and tourism. It offers charming shorelines with beaches, steep coastlines, and moraine cliffs, nestled among gentle sandy areas. Nature and culture lovers will find a wealth of destinations along both shores: Flensburg with its historic old town and museum harbor, Glücksburg Castle, the Holnis peninsula with its protected salt marshes and lighthouses, as well as the Geltinger Birk nature reserve and the towns along the northern shore with the Gendarmenpfad (Gendarmen Trail) – a former border path along the Danish border. For centuries, the fjord has been shaped by passenger and freight traffic – historic steamers connected Flensburg with towns on both sides. Today, leisure boating, excursion boats, traditional yachts and marine activities dominate in Mürwik.
