Sønderborg Castle

and the impressive Alsion with university and Research Park, concert hall and café is beautiful landmark that helps emphasizing the historical significance, but they also tell a story of a city developing rapidly and with high ambitions. 

On a year-round basis, Sønderborg offers several cultural and musical experiences, both indoors and outdoors. Enjoy a symphonic concert in Alsion, or a rock concert in the parks. Ringridning is a cultural tradition in Southern Jutland. On selected days, you can experience historical ring jousting at the castle. Read more about the tilting festival. 

Guided walks in Sønderborg

are offered throughout the month of July, and when there is tilting in the city you can participate in a combined city and Ringridning tour. 

Enjoy Sønderborg on your own with a guide booklet of “Hjerte-stien” that is provided at the tourist office. Hjertestien is a designated running-path. The 5 km long trail in the heart of Sønderborg runs through parks and neighborhoods from different time periods and past several statues and local monuments.  

Dybbøl Mill at Dybbøl

was a central element of the war in 1864, a symbol of Danish prowess. Read more about the Battle of Dybbøl and 1864. At Ulkebøl Church there was a Danish flag hanging during the Prussian invasion. A priest from the church would not obey the order to take down the flag, resulting in the soldiers shooting and stomping on the flag. The Prussians were finally too much for the priest who moved to Zealand and took the flag with him. After the reunification in 1920, the flag returned and is now located in the church. 2014 marks the Sønderborg area’s 150th anniversary of the fateful events in 1864 – events that not only had serious consequences for South Jutland, but for the whole of Denmark.
