The Arènes de Lutèce are among the most important ancient Roman remains from the era in Paris, together with the Thermes de Cluny. Constructed in the 1st century AD, this theatre could once seat 15,000 people and was used also as an amphitheatre to show gladiatorial combats.
The terraced seating surrounded more than half of the arena's circumference, more typical of an ancient Greek theatre rather than a Roman one which was semi-circular.
The orchestra was surrounded by the wall of a podium 2.5 m high, surmounted by a parapet. The stage was 41m long. A series of nine niches were most likely used for statues. Five small rooms were situated beneath the lower terraces, some of which appear to have been animal cages that opened directly into the arena.
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. From its vantage point, the theatre also afforded views of the Bièvre and Seine rivers.
