With the CLIC project we aim to contribute to the “paradigm-shift” proposed in the United Nations Agenda 2030 for Sustainable Development (through Sustainable Development Goals) and in New Urban Agenda, towards the “humanization” of our cities (see paragraph 26). This is the real challenge of our time. It means in particular to contribute to: Regenerate the “connective infrastructure” of our city/society, going beyond the hyper-individualism and embracing interdependencies Regenerate community bonds, through regenerating the collective memory Helping subjects to move from I to US: to cooperate each other The Circular Economy is the co-evolutive economy, the economy of synergies, cooperation, collaboration, which is put in relationship with the circular city model and with cultural heritage, that have not been put in relationship before. The objective of this contribution is to identify tools and experiences that contribute to the regeneration of the European “connective infrastructure” through the creation of “heritage communities”.
