The excavations of the Roman Theater in Turin can only be viewed during a visit to the Museum of Antiquities. The ruins are what is left of the ancient Roman city of Augusta Taurinorum. In its heyday, the theater could accommodate around 3,000 spectators. Nowadays, it is located below the Royal Palace, of which it occupies part of the cellars.
Construction of the Roman Theater of Turin started in 13 BC. Initially, the entire complex (stage, seats and surrounding fence) was made of wood. Between 40 and 50 AD, a stone portico was added, and by the end of the century the entire structure was made of stone.
With the arrival of Christianity came a ban on theatrical performances and the complex was abandoned. At the end of the 4th century, it was replaced by a Cathedral.
In 1899, when a new wing was added to the Royal Palace, some ancient walls of the by then completely forgotten theater were discovered. It was decided to change the project, so as to be able to preserve the ruins of the monument.
The first period of restoration finished in 1911. Between 1960 and 1962 more excavations took place. From these, it became clear that there had been two pahases of construction. The extensive excavations led to a further restoration of aisles, porticoes and walls.
Besides the ruins of the complex itself, the archaeologists also found an ancient road, that separated the theater from the surrounding houses. Part of the excavations stretches to almost the present Cathedral. From there it is also possible to view parts of the ancient structure.
The semi-circular theater consisted of four sectors, separated by staircases. Its diameter was 70 meters. The stage itself was 44 meters long and 6 meters deep.
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.
