The construction of Don Álvaro de Luna castle was commissioned by the High Constable Ruy López Dávalos between the end of the 14th century and the beginning of the 15th century.There is very little left in the interior of the castle. The fires originating from the different wars have left, over time, only the walls of the building. In other periods it was used as a prison and cemetery, and today it is the municipal auditorium.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.
