Rather than treating ecclesiastical land as a closed or exclusively religious property, the communication argues that these concessions function as open, relational and territorially embedded spaces, shaped by collective practices that articulate spiritual, social and economic purposes. Drawing on the institutionalist notion of the "bundle of rights", the communication conceptualizes religious property not as an exclusive dominium, but as a plural and negotiated constellation of rights (use, access, management, exclusion) distributed among ecclesiastical authorities, local communities, farmers, youth groups and associations. This analytical framework makes it possible to capture how Christian communities operate as producers of space, generating forms of proximity, welfare provision and social coordination, often in contexts marked by weak state presence. Empirically, the contribution focuses on Catholic land concessions in eastern and western regions of the Democratic Republic of Congo, where church-owned land hosts a wide range of collective uses: sharecropping and subsistence agriculture, schools and health centres, parish halls, sports fields and spaces of sociocultural animation. These practices transform ecclesiastical land into multifunctional spaces of encounter, where religious life intertwines with everyday social and economic activities. Community is thus approached as a dynamic process shaped by shared practices, responsibility and negotiation, rather than as a fixed ecclesial identity. The communication pays particular attention to power relations and legitimacy beyond formal hierarchies, highlighting the role of lay actors and informal governance arrangements. Local charters, sometimes written, often oral, regulate access and responsibilities, translating an "architecture of encounter" into concrete spatial norms. These arrangements reveal how Christian communities generate hybrid public spaces.
