摘要：This inquiry is a reflection on the graffiti, understanding it as one social practice that allows the citizens attribute new senses for the urban spaces. The graffiters, when leaving yours signatures ? ?tags? ? in the walls of the city, transforms the public space into private space, for after, transforms them into public, now modified. We made an analysis of marks left for two groups of graffiters in the center of the city of Londrina ? Brazil. We observe that these marks interact with each other, establishing a net of senses. The city is transformed into a support where the people (in groups or individually) exercise the construction of yours identities through the establishment of the differences (within the dispute between groups and/or individual for the public) or in the overcoming of disputes ("by adding to the existing graffitis"). The graffiters, when inscribing yours "tags" in the urban universe, modifies the identity of the city, reconfiguring its landscape.
