This study analyzes the influence of urban public spaces on the configuration of State identity, examining how architecture, built environment structures, and power regulations become symbolic elements that shape national identity. The research proposes a methodological framework that links architectural design with urbanism through a participatory approach, considering the interaction between citizens, institutions, and the State in the production of symbolic spaces. Through a qualitative analysis of representative cases at various scales of government intervention, urban design patterns that reflect the state narrative and contribute to collective identity construction were identified. The results demonstrate that participatory design processes increase citizen appropriation of public spaces and strengthen the legitimization of state identity, establishing an interdisciplinary methodology applicable to contemporary urban planning that balances sociopolitical needs with community aspirations.
