The Department of architecture and Urban Studies (dastu) of Politecnico of Milan has been awarded ‘excellence department’ by the Italian Ministry of University and Research for the period 2018-2022. In these five years the department is exploring the complex and multiple phenomena that engendered processes of fragilization of the relation between space and society. A first work, presented in this section, is a description of some interpretations of territorial fragilities based on 14 different lines of research. The main goal of this work is to open a dialog on different definitions of territorial fragilities able to build a base - a common lexicon - for the development of this complex research program.
