Urban intervention is a phenomenon that nowadays is happening frequently on the metropolis. They are a result of creative actions that was generated from collective and cooperative participation of citizens interested in giving new significance to the public spaces. Those citizens demonstrate the will to exercitate their citizenship more broadly. Through the analysis of those objects, it was possible to verify the comunicational substracts derived from the processes of ressignification of these objects that compound the public space. It made evident that the language of the ludicity has a multisensory appeal, that drives attention of the citizen to messages of citizenship. The design employs a modus operandi capable of entrelace expertises as an activity that pontentializes the culture of participation on the public space. For this work, a bibliographical study was made about the following themes: concepts of space, landscape, territory and place; urban interventions; design methodologies; Ephemeral and Permanent; Ludicity and semiotical processes. The fieldwork was constructed with a survey of urban intervention examples and experiences in loco that evidentiates messages of leisure, information and citizenship contained on the ludic urban interventions that attribute new significations to the public space.
