Ehrenhausen Castle is well-preserved three-story and four-wing building from the 12th century. The castle was first mentioned in 1240. The current castle was built by the Eggenberg family in the 16h century. It was one of Austria′s numerous fortifications that secured the South and the East of the country against the Turks.
On the castle hill there is also the mausoleum of Ruprecht von Eggenberg (1546-1611) and his nephew Wolf von Eggenberg which was designed by Italian painter and architect Giovanni Pietro de Pomis.
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.
