Teatro Arriaga is an opera house in Bilbao. It was built in Neo-baroque style by architect Joaquín Rucoba in 1890, the same architect that built the city hall. It is named after Juan Crisóstomo de Arriaga, known in his time as the 'Spanish Mozart'. The theatre was rebuilt in 1985 after severe flooding destroyed it in August 1983.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.
