The Arènes de Lutèce and Thermes de Cluny; the Paris of Antiquity
Published on , in Paris

What is now Paris was once Roman (despite, of course, fierce resistance!). The Gallo-Roman city of Lutèce (Lutetia) was established in the last half century B.C. Much of this stronghold has been lost to time, but some vestiges remain, including the Arènes de Lutèce and the Thermes de Cluny, just a short way from the Hotel Observatoire Luxembourg.
