The Arènes de Lutèce are among the most important remains from the Gallo-Roman era in Paris (known in antiquity as Lutetia, or Lutèce in French), 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. Standing in the centre of the arena one can still observe significant remnants of the stage and its nine niches, as well as the grilled cages in the wall. The stepped terraces are not original, but historians believe that 41 arched openings punctuated the façade.
