The lower part of town (Unterstadt) and upper town (Oberstadt) are reserved for pedestrians only and connected by 2 stairways and a steep street. The name means “Castle on the Sea”, referring to the castle which, according to a tradition from 1548, was built here in 630 by the Merovingian king Dagobert I. The commune obtained the status of free city in 1299. In 1803 it was annexed to the Land of Baden. After WW2, it was part of the French military zone.
