Dionysus Theatre

The Theatre of Dionysus was a major amphitheatre in ancient Greece, built at the foot of the Athenian Acropolis. Dedicated to Dionysus, the god of plays and wine (among other things), the theatre could seat as many as 17,000 people, making it an ideal location for ancient Athens' biggest theatrical celebration, the Dionysia.
The theater was rebuild in the late fourth century using stone but earlier in the great period of Greek Theater (Aeschylus, Euripides, Sophocles, etc) wood was used.
