While teaching practices still remain based on documents with illustrative functions, it is important to question the training of initial and in-service high school teachers of history and geography. This article proposes an analytical grid for various documents related to the evolution of the Chute des Chaudières site between Gatineau and Ottawa. Between the protection of the heritage and revitalization of a disused industrial site, we propose a problem-solving approach to analyze a variety of documents including paintings and photographs of different eras. The analysis will be based on the structural perspective of Lefebvre (1974) and the architectural semiotics of Eco (1997) used to interrogate the production of space by society and how it can be perceived or analyzed through time. These historical, geographical, and civic issues make it possible to reflect on the status of the image in the teaching of these disciplines and the integration of practices centered on the criticism of a varied iconography.
