The oldest of the structures is the Theatre of Dionysos. The Theater of Dionysos (god of wine, music, and theater) was constructed in the 4th century B.C.over a stage area that had been in use during the previous two centuries. It was here that the Dionysiac Festials took place. Plays such as Oedipus Rex and Medea were performed here. The present structure is a mixture of the original stone work and reconstructions which were performed under Nero.

    Moving East and up the hill, the visitor comes across two sanctuaries of Asklepios, the god of healing. The temples date from the 5th and 4th centuries B.C. Since this complex (the theater and the Asklpieion) were constructed at the same time as the complex at Epidauros I am guessing this complex was built for the same reason: To use theater to aid in the recovery of the infirmed.

     Below the Asklepieion is the Stoa of Eumenes. The Stoa was built in the second century B.C. A Stoa is essentially a walkway that is covered by a roof held up by columns. This walkway served as an entry way for both the Theater of Dionysos and that of the Odeon of Herod Atticus.
