The History of Sønderborg and Als
From Ancient Times to the Middle Ages
Als and the area around Sønderborg have been inhabited for thousands of years. Archaeological finds show that the area was inhabited as early as the Stone Age, and numerous Bronze Age discoveries, including rock carvings and burial mounds, bear witness to its rich prehistory.
During the Viking Age, Als played an important role as a strategic hub in the Baltic Sea. Its central location enabled the Vikings to control shipping routes and defend against enemies.
In the Middle Ages, Sønderborg and Als became part of the Kingdom of Denmark, and the area grew in importance as a centre for trade and defence. The construction of Sønderborg Castle in the 13th century marked a new era in the region’s history. The castle was built as a defensive stronghold and later became the setting for many dramatic events in Danish history.
The Reformation, Wars and the Border Region
Sønderborg Castle played an important role during the Reformation and the Danish–Swedish wars. The castle is best known as the prison of Christian II, who was held captive here from 1532 to 1549.
During the 19th century, Sønderborg and Als became a focal point of the Danish–German conflicts. The war of 1864, which led to Denmark’s loss of Schleswig-Holstein, had a profound impact on the area. The Battle of Dybbøl was one of the most decisive events of the war and left a deep historical mark that is still commemorated today.
Following Reunification in 1920, Southern Jutland and Als once again became part of Denmark, and the area began to develop as an important border region with strong ties to both Denmark and Germany.

The town of Sønderborg is known for its vibrant cultural life, beautiful waterfront and focus on technology, with Sønderborg being home to companies such as Danfoss.
