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.
The park usually opens between 8 am and 9 am and closes between 8:30 pm and 9:30 pm, depending on the season. Please check the websites.
Free admission.
