On the south side of the Acropolis is located the remains of the ancient Theatre of Dionysus. In this area there was the sanctuary of Dionysus whose worshipers came from Eleutherae of Boeotia and for this reason he was called Dionysus Eleuthereus and was celebrated every year during the month of Elafivoliona in late March to early April, the Great Dionysia festivities were held in glorious celebration in honour of the god and was one of the most important festivals of ancient Athens. On this side of the Acropolis was created The Ancient Greek Theatre as a place of significance and all of the plays that were written during ancient times were to be shown firstly at the Theatre of Dionysus.

In the first years of its operation there were wooden stands in the Theatre of Dionysus. During the period of the archon Lycurgus, the Theatre was expanded using stone. It is estimated that at that time The Theatre of Dionysus could hold an audience capacity of more than 15,000 people. In the first series of rows there were 67 marble seats for the officials. This was the custom of Proedria (presidency) and each seat was inscribed with the name of the person for whom it was intended.

Over the subsequent centuries, the theatre was destroyed. For several years ​​works of excavation, maintenance and restoration of the Theatre of Dionysus using materials similar to those used in ancient times has been in progress and the ancient theatre slowly returns to its original form. When you walk around the orchestra and the stands you are dominated by a sense of awe, when you think that here on this site, 2500 years ago, Theatre was born.
