Nordborg Slot

Nordborg Castle was, for much of the Middle Ages, a possession of the Danish crown and often served as part of the income base for royal widows. In 1571, Hans the Younger, brother of Frederik II, inherited his mother Queen Dorothea’s estates on Als and Sundeved, including Nordborg. A resourceful man, Hans the Younger expanded and improved his holdings over the next 50 years, initiating several construction projects in and around Nordborg Castle.

When Duke Hans the Younger died in 1622, his estates were divided into smaller duchies, including the Duchy of Nordborg, which passed to his son Johan Adolf. However, Johan Adolf died just two years later, and the duchy was inherited by his younger brother Frederik.

Folk High School and Boarding School
In 1909, the castle was purchased by the town of Nordborg. The German-oriented mayor, Klinkers, dreamed of building a folk high school to counterbalance the Danish folk high schools north of the border. The castle was subsequently rebuilt according to designs by architect Eugen Fink, and in 1910 it was leased to the German Folk High School Association in Northern Schleswig.

After the Reunification in 1920, the castle was purchased by merchant Johan Hansen, who established the Nordborg Castle Foundation. Since 1922, the foundation has operated a Danish boarding school on the site.

During World War II, the castle was taken over by German soldiers and transformed into a naval training base for special forces.

In recent years, Nordborg Castle has also served as the venue for the Nord-Als Music Festival.
