Sønderborg
Sønderborg (Danish pronunciation: [ˈsønɐˌpɒˀ]; German: Sonderburg [ˈzɔndɐbʊʁk] ⓘ) is a Danish town in the Region of Southern Denmark. It is the main town and the administrative seat of Sønderborg Municipality (Kommune). The town has a population of 28,333 (1 January 2025), in a municipality of 74,096. In recent times, Sønderborg is a center for trade, tourism, industry, and education in the region of Southern Denmark. The town is the headquarters for several industrial companies. Sønderborg joined the UNESCO Global Network of Learning Cities in 2016.
The town of Sønderborg is home to Sønderborg Castle (Sønderborg Slot), the Royal Danish Army's Sergeant School (until 2013) and Sandbjerg Estate (Sandbjerg Gods). Sønderborg castle is in the centre of the town, and houses a museum focusing on the history and culture of the area. The museum is open all year. Sandbjerg Estate, which had belonged for many years to the Dukes of Sønderborg, and then to the Reventlow family, was donated to Aarhus University in 1954. In addition, Sønderborg has a castle-like barracks built by the German military in 1906, placed centrally by Als Fjord, opposite Alsion (see picture below).
The old part of Sønderborg is located on the island of Als, but some of its western suburbs have spread onto the mainland of Jutland into what had been the interior of the fort of Dybbøl.
Prior to the Second Schleswig War of 1864, Sønderborg was situated in the Duchy of Schleswig, a Danish fief, so its history is properly included in the contentious history of Schleswig-Holstein. In the 1920 Schleswig Plebiscite that returned Northern Schleswig to Denmark, 43.8% of the city of Sønderborg's inhabitants voted for the cession to Denmark and 56.2% voted for remaining part of Germany.
The town of Sønderborg lies on both sides of Alssund; the narrow strait between these two sides is called Als Strait (Alssund). Two road bridges connect the city across the strait: the 682-meter-long (2,238 ft) Als Strait Bridge (Alssundbro), built in 1978–1981; and the 331-meter (1,086 ft) King Christian X's Bridge (Kong Christian Xs Bro), built in 1925–1930.
Sønderborg hosts several institutions of higher education. the University of Southern Denmark, University College South (Danish: University College Syd), and Business Academy SouthWest. Due to the local economy, the University of Southern Denmark offers several types of degrees in engineering such as: mechatronics; electronics; innovation and business; as well as degrees in economics, languages and European studies.
The technical school EUC Syd has a campus in Sønderborg, and offers a variety of trades programs, as well as the HTX high school diploma and the International Baccalaureate Diploma program.
Sønderborg is an economic hub in the region of Southern Denmark, with industries within electronics, manufacturing, food processing, Information Technology and telecommunications among others, with several companies headquartered in and around the town.
