Una nuova centralità per la città di mezzo. A new centrality for the middle city

The text aims to look at peri-urban and interstitial places between cities, defining them as "undecided places", that is, places that are still in the process of finding their own identity. Their vulnerability is the bearer of fragility and degradation, but it can also be considered as an opportunity for easy modelling of the places themselves, capable of becoming protagonists of innovative urban structures at the service of the territory. Looking first at Europe, with the definition of “Metropolitan city”, and then at the national context, the text focuses on the Delrio law, which, along with the administration of the metropolitan city, becomes an opportunity for undeniable extraordinariness from different points of view, in particular the one of urban regeneration. The most appropriate methodological approach, for the purposes of effective planning, is certainly the one that starts from the regeneration of the landscape in order to arrive at the identification of an integrated and sustainable tool in which the draft plan, through the involvement of the population and institutions involved, becomes the expression of a basically choral process of elaboration.
