Abstract: The PRISMA project is situated within the debate on urban inequalities related to religious architectures and worship practices, examining how these inequalities are materially and symbolically inscribed in the urban space of Rome. Building on the GAP project (Horizon MSCA 2023-PF-01), PRISMA extends the analysis to iconic and hybrid forms of religious architecture, highlighting asymmetries of visibility, recognition, and access to urban space that characterize different religious groups. Through the creation of a Visual Archive based on photographic documentation and 3D surveys, the project maps a plurality of architectural configurations - monumental, hybrid, and adaptive - revealing differentiated levels of legitimation and access to urban resources. The paper will focus on the most significant configurations emerging from the construction of the archive, with particular attention to secular spaces that have acquired religious meaning as expressions of adaptation and negotiation strategies adopted by minority religious communities operating under regulatory, economic, and symbolic constraints. The contribution also shows how processes of institutional recognition and heritage-making contribute to structuring and reproducing inequalities by incorporating certain architectures into official heritage circuits while leaving others in conditions of material and symbolic marginality. By integrating a digital dimension through visual archiving and its subsequent translation into immersive environments, PRISMA finally offers a critical reflection on emerging hybrid spatialities, highlighting both their potential to render marginalized religious architectures and practices visible and their limits in overcoming existing asymmetries.
