Teatro antico di Taormina is an ancient Greek theatre in Taormina, built in the third century BC. The ancient theatre is built for the most part of brick, and is therefore probably of Roman date, though the plan and arrangement are in accordance with those of Greek, rather than Roman, theatres; whence it is supposed that the present structure was rebuilt upon the foundations of an older theatre of the Greek period.
With a diameter of 120 metres (after an expansion in the 2nd century), this theatre is the second largest of its kind in Sicily (after that of Syracuse); it is frequently used for operatic and theatrical performances and for concerts. The greater part of the original seats have disappeared, but the wall which surrounded the whole cavea is preserved, and the proscenium with the back wall of the scena and its appendages, of which only traces remain in most ancient theatres, are here preserved in singular integrity, and contribute much to the picturesque effect, as well as to the interest, of the ruin.
From the fragments of architectural decorations still extant we learn that it was of the Corinthian order, and richly ornamented. Some portions of a temple are also visible, converted into the church of San Pancrazio, but the edifice is of small size.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
