On the occasion of the XXI Triennale di Milano International Exposition, Milan houses the exhibition named City after the City. If we admit that cities are no longer able to self-certify traditions and roots, then we can say we are facing a divisive event of great impact, which above all testifies to the opaque nature of today’s urban model. City after the City examines the symptoms of a global trend towards going beyond the conventional city. In collaboration with the curators Pier Luigi NIcolin, Nina Bassoli and Bruce Mau Design we research and designed Street Art Pavillion. Street art is widespread in many cities, bringing renewed attention to social and visual communication in city thoroughfares. Between public and private, individual and society, architecture and the environment, permitted and prohibited, street art concerns both the emotive sphere of the individual and the conventions of the public space.
