Rio de Janeiro city is under a space production process cheapened resulted by other two process understood as space metropolization’s facets: the marketfication and the militarization. One expression of such trivialization of space is noted thru Cracolândias, as the crack scene are popularly known. Cracolândia is one representation that hide and mask the space contradiction, one facet of trivialized urbanization. On the other hand all this movement raises the contestation and transgression, protest. In this meaning, from what Harvey calls free flow of imagination, objectify to search ways of framing alternatives and possibilities front of these everyday life and programed by world merchandise. From space of representations that is Cristolândia, we noted the spaces practices of missionaries as a fight for reappropriation of urban space by their utopia space, built over one base formed by values as justice, liberation and compassion. This struggle is noticed as one among many other. The research guiding principle is to open the alternatives and possibilities, seek cracks to overcome the actual state of affairs. If the representation of Cristolândia challenges the representation of cracolândia and pursuit to turn it, we believe that is possible to transform the entire space, the entire city. It is a utopian project, but without utopia there is no action. Therefore, utopia is an urgency needed for revolution.
