Ochsenhausen Abbey was a Benedictine monastery was founded according a legend in the 9th century when there was a nunnery here called 'Hohenhusen', which was abandoned at the time of the Hungarian invasions in the early 10th century. A ploughing ox later turned up a chest of valuables buried by the nuns before their flight, and the monastery of Ochsenhausen was founded on that spot.
The first Abbey Church of Ochsenhausen was in fact dedicated in 1093. The monastery was initially a priory of St. Blaise's Abbey in the Black Forest, but gained the status of an independent abbey in 1391. In 1495 it became Reichsfrei (territorially independent).
The abbey was secularised in 1803 and in 1806 its territories were absorbed into the Kingdom of Württemberg.
Much of the buildings still survive. They were extensively refurbished in the Baroque style. The Baden-Württemberg State Youth Music Academy is accommodated in part of them. The former abbey church is now the parish church of St. George's.
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.
