The Alcázar of Toledo was originally a Roman palace from the 3rd century, but it was restored under Charles I (Holy Roman Emperor Charles V) and his son Philip II of Spain in the 1540s. In 1521, Hernán Cortés was received by Charles I at the Alcázar, following Cortes' conquest of the Aztecs.
The façades are Renaissance in style, and it has towers and crenellated defences according to a preliminary design by Alonso de Covarrubias, subsequently completed by Juan de Herrera. After the last reconstruction it became the site of the Army offices and museum.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.
