The Nus castle stands above the same name village on a rocky projection, which dominates the entrance to the valley of Saint-Barthélemy. According to available documentation, the building can be traced at least as far back as the end of the 13th century, although the quadrangular turret, which collapsed at the start of the 20th century, and which stood in the eastern sector of the castle, can be compared to the towers erected in the valley during the 11th and 12th centuries. The final layout of the castle, which was modified on several occasions during the 14th and 15the centuries, was the product of a radical reconstruction campaign which took place around 1595, the date inscribed on the architrave at the entrance to the courtyard.
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.
