Acaya Castle wa built by the Knight Alfonso of Acaya in around 1506. In the following years, his son Gian Giacomo dell'Acaya, a famous architect, rebuilt the entire complex, transforming it into a fortified hamlet and making it the main centre of his estate. He also renamed it Acaya. After his death in 1570, the hamlet was sold and Acaya began to decline slowly, until its rebirth in the 20th century.
The Castle, which has a trapezoidal base, is accessible through a single bridge. The fortified walls are reinforced by two cylindrical towers. A stairway leads up to the rooms on the upper floor, including the bastion hall, with its painting of the Spanish Kings' coats of arms, and a room decorated with classically-styled motifs carved in Lecce stone.
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.
