Ritualization operated by analyzing macro-sectors in a city (e.g., neighborhoods) has concluded irreversibly for condemning some dilapidated areas instead of others. Taking its cue from the scenario of the 17 Sustainable Development Goals, particularly Goal 11-Make cities inclusive, safe, resilient and sustainable (United Nations)-the realized analysis links a sustainable urban design with the citizens' role in the city in a particular urban landmark, the "local town market area" (LTMA), with a focus on developing the well-being of the local community, also referred to as the psychology of sustainability and sustainable development. Principal methods of inquiry used, along a geospatial Google-driven investigation, were self-observation and self-assessment, which reflect both the study of self-organizing systems in the context of complexity and systemic theory, choosing to detect the spatial state of a specific area, as it has neither official nor institutional boundaries. The approach to crime prevention through environmental design (CPTED) is therefore discussed through the maximizing of the LTMA functional urban unit in Enna, Sicily, to reach the idea of a community that is innovative and participatory.Keywords: sustainable urban environment; psychology of sustainability and sustainable development; systems theory; self-organizing systems; spatial crime attractors and detractors; geospatial investigation Google-driven; areas with no institutional boundaries; quadrant counts method
