History+
Between 90 and 120 AD, the amphitheater was constructed in the Roman colony of Nemausus, now Nîmes, modeled after the Colosseum in Rome. It accommodated 25,000 spectators across 34 rows of seats, divided into four sections. The oval structure measures 133 meters in length, 101 meters in width, and reached a height of 21 meters. The facade was once adorned with two stories, each featuring 60 arcades. During the Migration Period, the structure served as a refuge and was converted into a fortress with houses and churches. In 1863, it was transformed into a bullfighting arena, a use that continues to this day.
