This presentation explores the making of the interreligious field, understood as a semi autonomous space where institutional logics, struggles over resources and ideological projects intersect. By integrating neo institutional theory, Bourdieu's field perspective and Hall's articulation theory, we develop a framework that captures both the structuring forces and the tensions that reshape interreligious practices. Neo institutional theory highlights processes of isomorphism and functional differentiation; Bourdieu situates these dynamics within struggles for legitimacy and symbolic capital; Hall clarifies how meanings and boundaries are discursively constructed and contested. Empirically, the article focuses on Turin, a city often seen as a national vanguard in governing religious diversity. Its distinctiveness stems not from inherent progressiveness but from a contingent articulation of historical factors: minority emancipation rooted in the Statuto Albertino, administrative continuity since the 2006 Olympics and ideological debates on pluralism and secularization. Initiatives such as the Comitato Interfedi and the Patto di Condivisione illustrate how Turin functions as both laboratory and vanguard, showing how the interreligious field operates as a governance tool, an ideological arena and a resource for reimagining urban pluralism.
