Arènes de Lutèce
Along with the Thermes de Cluny, the Arènes de Lutèce are the only vestige left of the early Romans of Lutèce. This former amphitheater, likely first constructed in the first century AD, and reconstructed again in the 6th century, could contain more than 15000 people. The ruins were discovered at the end of the 18th century, and thanks to its classification as a Historical Monument, the Arènes de Lutèce can now be visited everyday for free.
