Venice's unique double fractal urban fabric, with its intricate canals and human-scale architecture, forms a crucial part of the city's identity and sense of community. However, overtourism significantly threatens this delicate balance, altering not only the physical environment but also the social and cultural dynamics that make Venice distinct. This chapter explores the interplay between the urban fabric of Venice, and the emergent phenomenon of Temporary Appropriation (TA), which reflects the ways residents adapt public spaces for daily life. Through assemblage theory and agential realism, we analyse how tourism erodes the sense of community by overwhelming the city's public spaces, transforming them from local resources into sites of spectacle and commodification. Drawing from sense of community and spatial data analysis, we uncover the dual role of Venice’s architectural design: while it fosters community resilience by encouraging social interaction, it also amplifies the pressures of overtourism. The findings presented here advocates for rethinking tourism management strategies that prioritize both the preservation of Venice’s built environment and the urban identity.
