The first construction phase of the theater dates back to the late 5th c. B.C. It included fixed seats and a wooden stage.
A new orchestra and staging were added during the Hellenistic period. In the early 1st c. A.D., the gradient of the seats became steeper and a covered stoa was added to its upper part. The scene building was reconstructed towards the middle of the 2nd c. A.D., acquiring a three-storied façade with a colonnade and reliefs under the columns. During late Antiquity, theatrical aesthetics changed and the theater orchestra became a gladiators’ area.

The courtyard to the east of the stage reveals a stone slab in its floor, put to second use, which bears a Latin inscription referring to the aedilis (financial manager) of the city of Erasto. The theater area continued to be in use also in the Byzantine period.
