The Roman city of Cemenelum was founded in the 1st century AD as a staging post for Roman troops in the Alpes Maritime region and it later became the regional capital. Favorably located, Cemenelum was chosen as the principal seat of the province of Alpes Maritimae by Augustus in 14 BC. Later, the Romans settled further inland, on the opposite side of the river Paillon. Remains of the town on the Hill of Cimiez date to the 3rd century AD.
The Amphitheater at the northern end of the site was originally built of wood and seated only 500-600. It was later rebuilt in stone during the Severan dynasty (AD 193-217) with its capacity expanded to 5000 persons. The vaulted remains at Nice may be compared to other small amphitheaters in garrison towns in the Roman Empire. Seating in the amphitheater reflected class distinctions between officers and enlisted men, with the structure at Nice-Cimiez divided into two sections reached by separate entrances.
The amphitheatre is not as big or as well-preserved as those found in Arles or Nimes, but along with the Roman baths and arena, visitors can gain a sense of wonder into Roman life by paying a visit to the archaeological museum (Musée Archéologique de Nice-Cimiez) on Avenue des Arènes.
The Roman baths complex is the largest known in Gaul.
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.
