Green Networks Between the Historic City and the Sapienza Campus

This paper outlines urban regeneration strategies for the Sapienza University campus in the San Lorenzo district, an area where progressive building densification has transformed open areas into residual spaces lacking environmental functionality. To address these dynamics, the paper proposes the creation of a green and pedestrian network structured on two levels: a primary grid integrated with existing street infrastructure (widened sidewalks and tree planting) and a ring of secondary connections at the neighborhood scale, utilizing courtyards and underused spaces. The methodology relied on a detailed field inventory of residual open spaces, both paved and vegetated, conducted with the active participation of students and the local community. By analyzing international best practices (such as London’s Pocket Parks and Paris’s *Parisculteurs* program) and evaluating the manifold environmental, microclimatic, and social benefits of green infrastructure, the study highlights the need for an integrated approach. This approach, based on public incentives, shared regulations, and the progressive removal of barriers between the university and the neighborhood, aims to foster social cohesion and climate change adaptation.
