ABSTRACT
The mapping of the city of Lyons in the early twentieth century has not deserved enough attention compared to the number of texts dedicated to maps and mapmakers of the nineteenth century. From the cartography related to the urban administration to military mapping, several collections constitute valuable resources to understand the changes in the city throughout this period and deserve more attention. This paper focuses on two main issues that seem to emerge: the strengthening of a detailed mapping - 1:500 to 1:2000 as well as an "extended" cartography which depicts the city in the midst of metropolization. It proposes to analyze continuities and ruptures in the maps produced up to the end of Second World War, trying to suggest new lines of research
