Strategie di ridefinizione semantica della città. La street art e i segni di riscrittura urbana

In this paper we will analyse street art by focusing on the effects of meaning that this form of art produces in its relationship to urban elements and spaces and, conversely, how these enter significantly into artistic representation. In other words, the central theme will be the complex relationship between pieces of street art and the surfaces used (walls, shutters, barriers, buildings, etc.), which are anything but neutral loca- tions. This structural relationship – which is an internal mechanism of the urban text – raises broad and specifically semiotic questions such as the representation of a city, its internal conflicts and the subjectivities that seek to re-write it
