Stability of Urban Forms and Resilience of a System: The Case of Pre-Modern Parisian Street Network

In this paper, my aim is to show how edifying it can be to adhere to the concept of resilience proffered by C. S. Holling in order to better understand the complexity in which urban environments evolve. To do so, I study here the example of the Parisian street network during the Medieval and Early Modern periods. I show to what extent this network as well as the type of shops along certain streets remained stable over the long term, while also demonstrating that changes were indeed very frequent when one considers the buildings themselves. This apparent paradox can be explained by complex interactions that resilience can help to explore. I show in the third part of this paper that identifying the system of resiliency that produces stability in the Parisian street network leads to an understanding of the socioeconomic mechanisms behind the observations made at different levels.
