In the center of the village Íllora, at the top of a rock, there are the ruins of the old castle, although there are hardly any remains of the walls. This castle dates from the Caliphate period (9th-10th centuries) and is structured in three areas: the villa, the citadel and the suburb. Associated to that castle, there are a series of optical towers, among which the Tower of Brácana stands out.
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.
