Buenos Aires does not exist is an installation based on the research and production of images, cyanotypes and photographs from the archive regarding the first tunneling of creeks in the city of Buenos Aires in the 1930’s. The timeless and suspended photographs activate their memory from the water, in a dialogue with the archive that reveals the city from its entrails. The human shapes are erased and designed and the images are designed like postcards of landscapes, like an analogy of the landscape postcards with which the national imaginary was constructed in the first half of the XXth century. The installation proposes a body of water, a play of city sights from above and below, as a possible metaphor of the landscape, invisible, but not absent, to question the possible relationships and bonds between the city, its technology and nature, delve into the materialities and temporalities of photograph and archive(s) beyond representation, in dialogue and tension with the aesthetics and imaginaries of progress.
