Making a roundabout happen. Rondabout, unlilly location an autonomous politi-sation. – The article looks back at the daily experience of some sixty activists on a roundabout in the Isère region that was occupied continuously from November 2018 to March 2020. The ethnographic point of view assumes the double empirical posture of engagement in the yellow vest movement and a participatory observation methodology with about sixty interviews. On the roundabout, the yellow jackets show a constancy in participation, debates, popular education workshops, own actions or convergences with other organizations. The interaction between the development of the «no place» of the roundabouts and the construction of a new public space for living and deliberation is the source of a new creativity and political maturation opening up an instituting process of individual and collective autonomy in Cornelius Castoriadis’ sense.
