This project investigates the evolution of Roman urban infrastructure in the western Mediterranean. Due to the longevity of many cities, the urban infrastructure (including the road system, public buildings and large living quarters) was continuously adapted to changing political, socio-cultural, economic and natural contexts. A multidisciplinary approach of the evolution of the urban infrastructure of several Roman cities, and of their architecture more specifically,  can shed new light on the resilience of Roman society, as well as on broader historic processes such as the evolution of socio-cultural values, changing political or economic circumstances, or new ecological challenges. The impact on humans, the actual users of this urban infrastructure, is central to this project.
