Schwonsburg

The Schwonsburg fortification stands on a peninsula along the Schlei river, directly opposite to the town of Arnis in Schleswig-Holstein.

Built around 1415 under the direction of King Erik of Pomerania, the fortification served as a strategic defensive position controlling water routes.

Archaeological investigations in 1903 revealed significant late medieval earthworks, contributing to the understanding of northern German defensive structures.

While no visible remains exist at the site today, visitors can access the location by taking the Sundsacker ferry connection from the nearby town of Arnis.

The fortification site now contains only two houses on its elevated position, marking the location where the medieval structure once controlled the waterway.
