At the edge of Rome there is a mosaic made of tiles that stay together with force. A microcosm where harmony is a necessity, as the roots break the concrete. This place is known as Tor Sapienza, a neglected working-class neighbourhood at the eastern borders of the Roman periphery. In November 2014 it stopped being a suburb for few days and it found himself at the center of media attention. The revolt against an accomodation holding centre for refugees hid old and deep problems. The problems of a community so close to the urban border to feel beyond, expelled, forgotten. And today those problems remained, while the district has returned to its isolation and the structure has been moved elsewhere. Tor Sapienza concentrates in a modest perimeter the complexity of the large metropolitan suburbs. Tor Sapienza is the gold of the Romanian Orthodox Church, the shadows where the transsexuals prostitute themselves, the luxury hotel squatted by twenty nationalities, the Roma camp, the humidity of the shops and garages become abusive homes. And above all, the cornice of the popular buildings of seven floors, a closed rectangle that include more than 500 apartments. The work reflects on the complexity of Tor Sapienza through the variety of its characters highlighting those elements of social exclusion that characterize the outskirt of Rome.
