Sausenberg

Sausenberg was a lordship in the Holy Roman Empire between Freiburg and Basel. In 1337 the Hachberg-Sausenberg margraves, a branch of the house of Baden, held it alongside nearby Rötteln.

In 1444 the margraves acquired Badenweiler, joining it to Sausenberg and Rötteln in the Markgräflerland. The last margrave Philip died without sons in 1503, and Christopher I of Baden inherited his lands. French troops destroyed Sausenburg Castle in 1678 during the Franco-Dutch War.
