The city presents itself as a space for ethical, aesthetic and political productions. In this scenario, how to think the relation between space and subjectivity? In this text is presented the Entrespaços intervention, part of a multidisciplinary research project carried out between 2013 and 2015. During this process, we led two Urban Intervention Workshops, held in the city of Belo Horizonte (BR) and Poitiers (FR), with the starting point of drift experiences, inspired by the Situationists and other poetic-political resources used to unleash expressive processes and reflections on the subject in question. Now we describe the creation process of the workshop, as well as the initial and partial theoretical views traversed. We bring into focus the tensioning relationship between Science and Art. We believe that the production of knowledge we propose goes against the hegemonic methodological prescriptions, by admitting the inventive founding character of a Science-Knowledge Art; but we also recognize the difficulties in granting a technical severity with which we could measure what our work has displayed. It is through this experience report and under these circumstances that we return to dwell in memories, images, records and conversations that could map the path traversed.
