The political and social networks seen in a city consist of a diversity that entails complexity spaces. On the one hand, the homogeneous, abstract, and geometric city; on the other hand, a poetic, narrated, and experienced city walked by human beings; two spaces in reciprocal coexistence (sociospatial spheres). This is the case of Medellin City1, a reflexive scenario of this text. Lives, experiences, and perceptions of individuals are seen in this city, duly framed within a biopolitical network of the urban space and market economy, which is reflected in press and filing images selected for a critical address of the city. Architectural models of a city show symbolic efficiency related to social/technological devices to move merchandise, bodies, territories, and space management practices. In this way, the text includes an analysis of the existence of power which should be thought beyond a legal context by spreading it to a set of manifestations about bodies comprising the constructed urban network. The power, instead of being a judicial marker, becomes operation and marking over bodies. Resistance and domination, as tension in complexity, trigger a number of experiences within the heterogeneity of inhabited places that imply urban heterotopias.
