The research investigates a series of spaces of migration in France, identifying thresholds and encounters between spaces generated by the urgency of received and rejected bodies. Practices of containment, control, and protracted displacement coexist with the production of collective resistance and solidarity. The proximity of the ambiguous forms of these legacies establishes the equally ambiguous management of bodies and spaces, building the infrastructure of waiting. The result in the urban and rural dimension is the generation of a series of sequences on edge, marked by the simultaneous intertwining of mobility and immobility, visible and opaque; spaces between the camp and the city, identified as “spaces of holding”.
