How did Roman rule change cities in Gaul?

Under Roman rule, cities in Gaul underwent a significant transformation as they were assimilated into the Greco-Roman world. This process was characterized by the development of administrative centers known as civitas-capitals, which were either existing towns like Lutetia or newly founded ones like Augustodunum.12

Key changes to these urban centers included:

• Classical Planning: Cities were developed according to Mediterranean standards, featuring checkerboard street grids.12
• Public Infrastructure: Local magnates funded the construction of imposing administrative and recreational buildings, including forums, public baths, and amphitheatres.12
• Romanization of Status: Competition between local leaders shifted from warfare to achieving higher levels of Romanization for their communities.12
• Economic Integration: The expansion of a sophisticated Roman road system and river transport networks facilitated commerce, with cities like Lugdunum serving as vital hubs for trade and administration.132

During the Pax Romana, most of these cities remained unwalled, reflecting a period of relative stability and integration into the broader imperial economy.12
