The great building known as the Odeon of Pericles, which was used for the musical contests and the training of the tragic and comic choirs, was burnt down during the siege of Sylla (86 B.C.), and built again by Ariobarzanes ( 30 ). The excavation of this Odeon has not yet been achieved, and the architectural pieces coming from this site are very scarce. One of the angles was penetrating into the theatre of Dionysus.

A bird’s eye view over the Odeon of Pericles shows even better the importance of this building which was, apart from the theatres due to the surface of their rows, the largest building of the Acropolis.
