Abstract
The essay is focused on urban plannning and environment in the light of Modernism paradigm as a new way of building and conceptualising the metropolis. In particular, Russian researches in 1920s and 1930s on linear cities, such as those conducted by OSA group, are ambitious and remarkable examples of this. Modernist concepts, born in Europe and the U.S.A., were spread all over the world according to different dinamics. For this reason, such work tries also to rewrite the history of Modernism following Leonardo Benevolo' s study, who underlined as Postmodernism is a misunderstanding concept, and in a certain way to historically riconsider Modern Architecture.
