Festival of self-managed places in Brussels. The Festival du Coucou Puissant is a willingness of several occupations in Brussels to come together to strengthen the links between spaces. Our inspiration consists in proposing during a fortnight activities that we realize daily in our spaces. In our eyes, it is important that this festival opens a reflection on various subjects related to the city: right to housing, institutionalization of occupations, repression of squats by a penal law.
