The Ponte Pietra (Italian for 'Stone Bridge'), is a Roman arch bridge crossing the Adige River in Verona. The bridge was completed in 100 BC, and the Via Postumia from Genoa to Aquileia passed over it. It is the oldest bridge in Verona.
It originally flanked another Roman bridge, the Pons Postumius; both structures provided the city (on the right bank) with access to the Roman theatre on the east bank. The arch nearest to the right bank of the Adige was rebuilt in 1298 by Alberto I della Scala. Four arches of the bridge were blown up by retreating German troops in World War II, but rebuilt in 1957 with original materials.
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.
