Gw mau tau Roman period dari Nîmes. Jelasin dalam bahasa melayu

Nîmes became a Roman colony sometime before 28 BC, as witnessed by the earliest coins, which bear the abbreviation NEM. COL, "Colony of Nemausus". Some years later a sanctuary and other constructions connected with the fountain were raised on the site. Nîmes was already under Roman influence, though it was Augustus who made the city the capital of Narbonne province, and gave it all its glory. It was also known as the birthplace of the family of Roman Emperor Antoninus Pius.

The city had an estimated population of 60,000 in the time of Augustus. Augustus gave the town a ring of ramparts six kilometres () long, reinforced by fourteen towers; two gates remain today: the Porta Augusta and the Porte de France. An aqueduct was built to bring water from the hills to the north. Where this crossed the River Gard between Uzes and Remoulins, the spectacular Pont du Gard was built. This is  north east of the city.  Also, the Maison Carrée is one of the best preserved temples to be found anywhere in the territory of the former Roman Empire; it later inspired the design of the Virginia State Capitol at Richmond.  Nothing remains of some other monuments, the existence of which is known from inscriptions or architectural fragments found in the course of excavations. It is known that the town had a civil basilica, a curia, a gymnasium and perhaps a circus. The amphitheatre dates from the end of the 2nd century AD and was one of the largest amphitheatres in the Empire.

Emperor Constantine endowed the city with baths. It became the seat of the Diocesan Vicar, the chief administrative officer of southern Gaul.

The town was prosperous until the end of the 3rd century – during the 4th and 5th centuries, the nearby town of Arles enjoyed more prosperity. In the early 5th century the Praetorian Prefecture was moved from Trier in northeast Gaul to Arles. The Visigoths finally captured the city from the Romans in 473 AD.
