The Odeon of Herodes Atticus is a stone theatre structure located on the south slope of the Acropolis of Athens. It was built in 161 AD by Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped amphitheater with a three-story stone front wall and a wooden roof, and was used as a venue for music concerts with a capacity of 5,000. Andrea Bocelli gave a concert at the Odeon of Herod Atticus, in September 2010, attended by George Papandreou, the prime minister of Greece and Archbishop Ieronymos II of Athens, among others. All proceeds were donated to help cure cancer.
