The odeum was one of the most beautiful and impressive buildings of antiquity. Its size and material, the stage with the tall and elegant walls and the facade with the decorative niches are elements that impress us even today. The building in its original form had a three - storey facade , 28 meters high, and elaborate decoration, both externally and internally. The orchestra was paved with marble. The seats were also made of marble while the roof was made of cedar wood. It had a capacity of 5000 people. The odeum of Herodes Atticus was destroyed during the raid of Heruli. During the Turkish occupation the odeum was imbedded in the building of walls of the Acropolis castle. Today, it is used again as a theater for the summer performances of Athens festivals.
