Swedish Ski Jump

The Schwedenschanze is the remnant of an early Middle Ages fortified castle in the present-day district of Groß Thun in the south of the Hanseatic city of Stade.

The naming as Schwedenschanze is based on a mistake. For a long time, it was assumed that the ramparts that are still visible today were built during the presence of Swedish troops during the Thirty Years' War during the 17th century. In fact, the complex is about 1000 years older, dated by a beam that comes from a tree felled in 673. This makes the complex one of the few castles from the 7th century that are documented in the area between the Elbe and the Rhine.
