While, during the first half of the XXth century, the Haussmann cycle continues under the forms which we call post-haussmannism, Paris since 1890 knows other mutuations. The flats squalor, the city growth out of the Thiers military world, the new urbanistic theories from Germany, Great-Britain, and USA call the deepening of parisian changements.

The creation of cheap residences (HBM), the delimitation of squallid blocks on which the city will be rebuilt following the hygienic modes, the great radical visions of Le Corbusier and the great urbanistic projects inspired as by the Athens Chart as by the American ideal, give precidence to the modernizing intents which expire the haussmannism and also the ancient city form. The remplacement of the street-corridor and a block urban planning by a planning in slab and by a stratification of flows, as at La Défense, end up at large-scale operation more and mopre criticized. Seventies mark a fall to a city conception more reasoned in its scales, more sensitive at history and at the developped heritage. Eighties and Nineties know great François Mitterand's building sites (Louvre Pyramid, Opéra Bastille, Finance Ministry, Institut du Monde arabe-Arabic World Institut, Défense Great Arch), and especially a great rising of common architecture and public spaces (Villette parc, Bercy parc). The second half of the XXth century is finally marked by the suburb urbanisation which, until then, grown up without plan. Paris of the second half of the XXth century makes itself out of the administrative borders: the five new  Ile-de-France towns since 1965 and, today, the great equipment and urban planning works, linked at the Grand paris Metropolis (treated by Patrizia Ingallina).
