The Theatre of Dionysus is an ancient Greek theatre in Athens. It is built on the south slope of the Acropolis hill, originally part of the sanctuary of Dionysus Eleuthereus. The first orchestra terrace was constructed on the site around the mid- to late-sixth century BC, where it hosted the City Dionysia.
During the 5th century, the theatre was first used as a regular site for theatrical performances of plays written by the great tragic poets, such as Aeschylus, Euripides and Sophocles. The theater was a place to honor god Dionysus and the plays were performed as part of these celebrations. In fact, a large statue of the god had been placed in the front row so that the god himself could watch the plays and the sacrifices to his name.
