It was built with lavic material and grout, its benches were built with white limestone and with prized white marble lots of a materials of this theatre had been reused in the building of the medieval and modern town. The marble, for example, was reused in the building of the Norman cathedral. The sculptures and the inscriptions, rescued during the excavations, are showed in the Museum of Castle Ursino.
On the left of the theatre there is the Roman Odeon. It was created for a musical and oratorio exhibitions. Its chronology is not sure but probably it was built after the central building. It was built above all with limestone. Today you can entirely see only the cave.
