We will treat the phenomenon of street art as a national cultural current which, -due to specific characteristics of each city, has taken on each urban area different developments and connotations. In the first season of this documentary, we want to observe the history of Street Art as it is developed in Milan. We will tell how the concept of graffiti and murals has changed and how this art has contributed to the regeneration of peripheral urban areas, as well as public spaces have been returned to the city as places where today cultural and recreational activities take place.
