Hervé de Donzy, the Lord of Saint Aignan established Cornilly Abbey in the 11th century. It was authorized by Pope Urbanus II in 1091. The abbey grew rapidly, but in the 1357 it was destroyed by English Black Prince troops during the Hundred Years' War. Monks rebuilt the abbey, but it was again destroyed by religious fanatics in 1562. It was not rebuilt again and in the Revolution (1789) it was moved as a national property. Today impressive ruins remain, including parts of the 13th century church, western portal and choir. The Cornilly Abbey site is privately owned.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.
