In the context of migration and cultural diversity, the political mobilization of belonging has become increasingly important. Also at the level of everyday practices, conflicts are increasingly perceived through the lens of ethnic and cultural differences. Against this background, the project sets out to understand how belonging is mobilized in a particular social and spatial setting, and how this mobilization of belonging relates to the maintenance, crossing, or shifting of subjective and emotionally-laden boundaries. In order to do so, the project will develop a new methodology at the interface between arts and sciences, which will be based on the creation of a "laboratory" for the mobilization of belongings. This laboratory will be built by artists in the courtyard of a Gemeindebau (social housing complex), and will serve as a set where artists, scientists and citizens collaborate in the production of knowledge.
