The Archaeological Park of Dion includes, in addition to important findings, the Ancient Theater, where during the Olympus Festival the ancient tragedy is revived, while other performances are held. To the south and on the borders of the settlement of Dion, with the Sanctuary of Demeter in the west, is this unique construction of the Hellenistic era, which dates to the reign of Philip V (221-179 BC).
It is built on the slope of a natural hill, with a northeast orientation, which, according to Vitruvius, is suitable for good ventilation of the area. Construction-wise, the theater was shaped with excavation and artificial earthworks and the result of these interventions is the harmonization with the natural landscape, making it unique in its kind. After the installation of wooden stands, today it can hold 4,000 spectators.
