Lutetia: When Paris Was Gallo-Roman

Long before becoming the capital of France, Paris was a medium-sized Gallo-Roman town known as Lutetia (Lutetia Parisiorum).

🏗️ A city on both banks

Lutetia developed around two main areas:

• the Île de la Cité → the historical core
• the Left Bank (Sainte-Geneviève hill) → the Roman urban center

It was on the Left Bank that the Romans built the main public monuments:

• The Forum → located beneath today’s Rue Soufflot
• The Baths of Cluny → large thermal baths, still visible today
• The Theatre → located near today’s Lycée Louis-le-Grand

🏟️ The Arenas of Lutetia

The most impressive surviving monument is the Arènes de Lutèce.

It was a hybrid structure:

• both an amphitheatre (for games)
• and a theatre (for performances)

It could hold up to 17,000 spectators —
👉 nearly the entire population of the city at the time.

🚢 The Nautae of Lutetia

Lutetia’s wealth came from river trade on the Seine.

The Nautae (boatmen and merchants) formed a powerful guild.

They are known for the famous Pillar of the Nautae, a monument that combines:

• Gallic deities
• Roman gods

👉 A perfect example of cultural fusion in Gallo-Roman society.
