Castillo de Doña Blanca is a tower built in the 15th or 16th century to watch the Cádiz bay. It is named after lady Blanca de Borbón, who was imprisoned there.
The tower is built to the archaeological area. The remains of walls, necrópolis and parts of houses date from the eighth to the third century BC and were built by the Phoenicians. It is considered an ancient city with a significant development and urban planning, which shows the great power of this port city. The first traces of occupation in the mountains and around date back to the Copper Age.
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.
