The Arènes de Lutèce are among the most important ancient Roman remains 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.
