Sønderborg (Sonderburg)

One of the most beautiful locations amid South Jutland’s bays and islands, the town of Sønderborg (Sonderburg) lies on the northern shore of the Flensburg Fjord on the island of Als (Alsen). Danish until 1864, Sønderborg then belonged to Germany until 1920.
Today, with a population of 30,000, Sønderborg is not only a shopping destination for visitors from the surrounding area, but also has attractions of its own worth exploring.
Dating from the 12th century, the castle and its museum are the most important museum in South Jutland and one of the region’s oldest buildings. There is a beach south of the castle. The old town itself is characterised by its many Art Nouveau buildings. The German Museum of North Schleswig provides information about the region’s German history.
The harbour is particularly appealing, serving as a berth for historic ships as well as a marina and the starting point for the so-called Rum Regatta to and from Flensburg.
A few kilometres west of Sønderborg is the Dybbøl Banke History Centre (Historiecenter Dybbøl Banke). The decisive battle of the German-Danish War took place here in 1864, ending in a Danish defeat.
Two road bridges, including a bascule bridge, span the 250-metre-wide Als Sound.
