The effects of the Covid-19 crisis have shown the need to rethink our cities’ urban planning. This session aims to review the concept of ‘The City of proximities’ or ‘The 15-Minute City’, a model that pursues a new urban lifestyle to favor economic, ecological, and social value in the proximity by providing extensive access to essential local services within a maximum distance of 10 to 15 minutes on foot or by bicycle, to create a new multi-center city.
