Stegeborgs castle ruin
Stegeborgs castle ruin is located on a small island in Slätbaken, about 20 km from Söderköping. The castle was built around the 13th century to protect the entrance to Söderköping and during the Middle Ages it was one of Sweden’s most important fortresses and a royal castle until the 17th century. Among others, Gustav Vasa has housed here. The round tower of the castle is the only remains of the medieval fortress. The ruins are surrounded by a beautiful park with herb garden.
The castle ruins are open for visits every day of the week all year round and you can easily pay the entrance in a vending machine next to the castle ruins. There is also the possibility of having an audioguide in swedish, english or german if you visit the castle ruins when the kiosk is open.
