The Roman aqueduct bridge in Termini Imerese is the largest and best preserved in Sicily. The source was located 5 km east of the city, at the foot of Monte San Calogero where the remains of the two settling tanks can still be seen in the locality of Brucato.
The aqueduct needed to cross the Barratina stream and the earliest the crossing was made at Fontana Superiore with a siphon about 600 m long, of which the well preserved hexagonal compression tower remains, 16 m high and resting on a square plinth of 6 m sides. On five of the sides were windows and from the east side the conduit started. On this tower was once a large inscription, now disappeared: aquae Cornealiae ductus p. XX. The last letters ('twenty feet') perhaps corresponds to the sides of the building.
Later it seems that the aqueduct passed further downstream: in Figurella a double-order bridge of arches is still visible (originally nine in the lower, fifteen in the upper: two arches for each order collapsed), 14 m high. The structure with facing blocks is the same as that of the amphitheatre and the curia and shows that it belongs to the same building project of the Augustan colony.
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.
