Urban space, conceived as a living fabric where the different identities that live and travel together, gives the contemporary artist a source of inspiration and a place conducive to action and experimentation. Critically, look into the underground problems hidden under the false idea of a planned, inert and stable city. The aim of this article is to identify some of the strategies used in artistic and communal interventions, all of which are embodied in the social fabric, which call on the citizen from the counter-narrative or democratic writing to disrupt the institutional and hegemonic narrative that prevails in society. To this end, we analysed some of the projects carried out by three artists belonging to three different generations in the American context of post-modernity: Martha Rosler, Janet Cardiff and Candy Chang, whose work, at the same time as subtle, focuses on the urban subject, the memory of the place, and the poetic nature of the territory as a tool of social transformation.
