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:
The Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
