Sønderborg - The main city of the region

Sønderborg is the main town in the region with around 27,000 inhabitants. The town developed around Søndre Castle, which name was later changed to Sønderborg Castle.

The town has a charming harbour front with cafés and restaurants and an intimate centre with loads of exciting shops. You can see many main attractions, banks etc. on the map. 

Sønderborg Castle and the impressive Alsion with its university, research park, concert hall and café are beautiful landmarks and underline the town’s historical significance. They also bear witness to Sønderborg’s rapid development and great ambitions.

Sønderborg offers world-class cultural and musical adventures all year round – indoors and outdoors. Enjoy a symphonic concert in Alsion or a rock concert in Mølleparken.

Dybbøl Mill at Dybbøl was during the war in 1864 a symbol of Danish bravery. Read more about the battle at Dybbøl and the year of 1864.

In Ulkebøl Church you can see a Danish flag, which waved for the 'Danishness', when the Prussians conquered the island of Als in 1864. The minister refused to obey the order of removing the flag, so the soldiers shot and stamped on it. The harassment was finally too much for the minister to bear, who moved to Zealand with the flag. After the Reunification in 1920 the flag was brought back to the church, where it can still be seen.
