Nurturing Cultural Heritages and Place Attachment through Street Art—A Longitudinal Psycho-Social Analysis of a Neighborhood Renewal Process

The Faro Convention emphasizes the link between cultural heritage and place-related identity, highlighting their role in fostering environmental and community belonging. Urban renewal projects centered around contemporary and street art have gained popularity worldwide but often exhibit unclear impacts on local populations. Few studies have explored this topic using a psychological and longitudinal approach. Addressing this research gap, our study analyzed changes in place attachment and neighborhood image five years after implementing a street-art-based renewal project in a Milan suburb. Moreover, the project’s impact on the neighborhood’s historical “personality” as perceived by residents and citizens (n = 296) was examined. A survey was designed and administered to compare trends in these variables between 2017 (project start) and 2022, applying content analysis and analysis of variance techniques. Results showed that street art inspired by local history and culture had a positive effect on residents’ place attachment and local image, without disrupting community traditions. However, no significant impacts were found among non-residents. These findings highlight the significance of urban renewal policies that prioritize a district’s social and cultural history. Such policies not only safeguard the citizens’ well-being and foster place attachment, but could also revitalize the local imagery, promoting innovation and creativity.
