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 Roman Theatre of Mérida is a construction promoted by the consul Vipsanius Agrippa in the Roman city of Emerita Augusta, capital of Lusitania (current Mérida). It was constructed in the years 16 to 15 BCE. One of the most famous and visited landmarks in Spain, the Roman Theatre of Mérida is regarded as a Spanish cultural icon and was chosen as one of the 12 Treasures of Spain.
The theatre has undergone several renovations, notably at the end of the 1st century or early 2nd century CE (possibly during the reign of Emperor Trajan), when the current facade of the scaenae frons was erected, and another in the time of Constantine I (between 330 and 340), which introduced new decorative-architectural elements and a walkway around the monument. Following the theatre"s abandonment in Late Antiquity, it was slowly covered with earth, with only the upper tiers of seats (summa cavea) remaining visible.
