Castle d'Eivissa, also known as Ibiza Castle, stands atop Puig de Vila. Its history goes back to the Middle Ages and the Moorish era. Currently, the partially restored complex is surrounded by thick walls, which are a reconstruction of the Renaissance fortifications.
The two defensive elements of the old fortress have been best preserved to the present day. The first is the Baluarte de Sant Jaume bastion, where you can see an exhibition of weapons used to defend the walls of Ibiza. The second is Baluarte de Sant Pere, which houses an exhibition devoted to the history of the castle and its subsequent extensions.
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.
