The contribution will focus on different situations in Italy and in France. Their theme though different in the each case is the form of contemporary society and the form of a project that has to do with it and with its transformations. How urbanism and architecture can deal with questions such as contemporary collective imaginary and myths, social space, integration/diversity? The case studies try to afford these dimensions using the project as a device to describe, to give an interpretation of the contemporary society: the project is intended as a producer of knowledge and as a producer of interactions among the different actors.
