This article systematizes the theoretical-practical research that the author has developed in the subject "Territory and Society" that is taught in the School of Architecture and Urbanism at Universidad Nacional de Colombia, based on the study of the relationship between society, space and nature. “Urban Interventions" become a field of experimentation to intervene the city from the senses and find new pedagogical and methodological tools that stimulate creativity in the understanding and transformation of urban spaces from the relationship with the body. Starting with the understanding of the trialectics of the body in space as a complex temporal space relationship in which the body captures diffuse flows of information and energy, it is possible to demonstrate that the body and the city are historically and spatially unfinished, malleable, porous projects for the performative activities in the environment, and are in constant expansion. Urban performative interventions are an artistic pedagogical instrument to experience different methodologies of creative relationship of the body with the city. They allow architecture and urbanism to transform the space through a trialectics relationship. The body-city-imaginary relationship changes the theoretical, methodological and creative approaches of architecture and urbanism understanding public space not only from its physical connotation but from its transformative capacity of social relationships and human behavior. Urban interventions, supported by urban imaginaries and thought about from architecture, open up to aesthetic-poetic-political languages and allow approaches to understanding urban space. In their development, they enable the univocal looks of the material space and place them in a crisis of interaction with the individual and the social body. They are not proposed as an alternative to the objective views of the production and reproduction of space, but as a complement to reach the complexity of the trialectics relationship of the conceived, lived and perceived spaces.
