Thoughwe usually think of Street Art as a predominantly visual creative movement, thediversity of urban intervention practicesescapes conceptual labels. Images and objects with a variety of intentions(expressive, playful, self-affirming, artistic and political-militant) alsoplay a pronounced role in exercising collective and social memory. This is moreand more often the case of the artistic interventions carried out over the concretetiles of Plaza Moreno, central hub of the city of La Plata, near BuenosAires, Argentina. Different collectives have expressed themselves there,seeking not only to make their demands visible, but also to build meaning andimaginaries within a ?geography in conflict.?The images in the plaza are there as complex artifacts whose everyday presencedoes not allow history, or the events lived in these territories, to rest.
