The Arènes de Lutèce are among the most important remains from the Gallo-Roman era in Paris (formerly known as Lutèce in French or Lutetia in Latin), together with the Thermes de Cluny. Lying in what is now the Quartier Latin, this amphitheater could once seat 15,000 people, and was used to present gladiatorial combats.

Constructed in the 1st century AD, this amphitheater is considered the longest of its kind constructed by the Romans. The sunken arena of the amphitheater was surrounded by the wall of a podium 2.5 m (8.2 feet) high, surmounted by a parapet. The presence of a 41.2-m- (135-foot-) long stage allowed scenes to alternate between theatrical productions and combat. A series of nine niches aided in improving the acoustics. Five cubbyholes were situated beneath the lower terraces, of which three appear to have been animal cages that opened directly into the arena. Historians believe that the terraces, which surrounded more than half of the arena's circumference, could accommodate as many as 17,000 spectators.

Slaves, the poor, and women were relegated to the higher tiers — while the lower seating areas were reserved for Roman male citizens. For comfort, a linen awning sheltered spectators from the hot sun. Circus acts showcased wild animals. From its vantage point, the amphitheater also afforded a spectacular view of the Bièvre and Seine rivers.
