The Santa María la Real de la Oliva is a Cistercian monastery in Carcastillo, Navarre. It was established in the 12th century. Present buildings date from 13th - 15th centuries.
Construction at the site is attributed first in 1134 to King García Ramírez of Navarre, known as the restorer. This king died in 1150 and the same year the abbey was founded, or refounded, as a daughter house of the Morimond and Escaladieu Abbeys.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.
