Invisible Cities - the experience of negative space

"What is today the city, for us? I believe I wrote something like a last love poem to cities, in a time when it’s becoming more and more difficult living them like cities. Maybe we’re coming to a moment of crisis of the urban life, and Invisible cities are a dream born by the heart of unliveable cities." - I. Calvino, Introduction to Città Invisibili, Mondadori 1983 Starting by a confrontation between two historical utopian projects (Arturo Soria’s ciudad lineal and Constant’s New Babylon) I try to investigate with a broad and heterogenous look the idea of adopting path as fundamental topic of the city: whether Soria or Constant, in different ways, suggest an architecture of roaming, a nomadic and virtual space, that is the same space of cosmopolis, an anticipation of globalized culture that’s identified in a flux-condition and not in a stasis-one. Ciudad lineal and New Babylon projects prophetically forestall many tendencies of contemporary urbanity, proposing an idea of cities that are at the same time hyperlocal and hyperplanetary, ahistorical and superficial, acentric and non-identitary, inhabited by people always in movement. Streets don’t conduct anymore just to some places, they are places themselves: the condition of movement, and the street trail that constitutes his support, represents the urban archetype that is the basis of all contemporary architectonical and social disposition. From the description and comparison of these two projects the Generic City emerges, alienate and privatized, where we’re living in nowadays.
