Küssaburg is a ruined hilltop castle located in Bechtersbohl, a village in the municipality of Küssaberg. The name may be derived from the Roman personal name, Cossinius, or from the German Kissen (Alemannic Chüssi) 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. The present ruins were owned by the counts of Küssenberg, the Bishopric of Constance and the counts of Sulz. The castle, which was later developed into a fortress, was destroyed by a fire started by its garrison on 8 March 1634 when the Swedish Army approached it during the Thirty Years' War and by a landslide on 25 December 1664. In the 19th century work began on uncovering the ruins which have since become a popular destination in the region.
References:Vufflens castle was built in 1425 on the site of a previous medieval castle by Henri de Colombier. It is the most significant example of a small group of fortified Romandy castles from the middle ages, characterised above all by its brick construction. In 1530, it was set on fire by Bernese troops. In 1641 it was acquired by the de Senarclens family. The castle is currently privately owned and cannot be visited.
