ACTOPOLIS is a large multi-year project of the Goethe-Institut in Southeast Europe in cooperation with the cultural institution "Urbane Künste Ruhr" from the Ruhr area in Germany. Its goal is to exchange experiences and jointly develop tools for artistic, urban and activist activities. In the form of a laboratory, the participants discussed the current issues of urban life, tried strategies of action, conducted interventions and encouraged critical reflections. During 2015, representatives from different cities exchanged project ideas in making, only to realize them in 2016, each in their respective city – Athens, Belgrade, Bucharest, Mardin (Turkey), Oberhausen, Sarajevo and Zagreb.
