Dilsberg Castle is a castle on a hill above the River Neckar. The castle was built by the counts of Lauffen in the 12th century. In the 13th century it became the main castle for the counts. In the 14th century it became part of the Electorate of the Palatinate and received town rights in 1347. During the Thirty Years" War, the castle was considered impregnable until Imperial forces under Tilly took the castle in 1622 after a long siege.
In 1799, French forces tried and failed to storm the castle. A 46-metre-deep well helped keep the defenders supplied during this assault. In the 19th century the castle fell into ruin and was used as a quarry. Today the castle and its town are a tourist attraction and are administered by the Staatliche Schösser und Gärten Baden-Württemberg, attracting thousands of visitors.
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.
