Küssaburg

The Küssaburg, Küssenberg or Küssaberg Castle is a ruined hilltop castle located at an elevation of 634 m above sea level in Bechtersbohl, a village in the municipality of Küssaberg, in the county of Waldshut in the German state of Baden-Württemberg.

The name may be derived from the Roman personal name, Cossinius, or from the German Kissen which means "cushion", after the shape of the mountain on which it stands.

The hill castle is one of the most important historic buildings on the High Rhine and a landmark of the county of Waldshut. It was probably constructed between 1125 and 1141.
