This paper explores the ways in which space-sharing practices between two religious communities in Berlin contribute to social and religious transformation. It draws on a case study developed for my doctoral thesis with the St. Georgis Eritrean Orthodox church, founded by refugees in 2015, and the St. Paul's protestant congregation in Zehlendorf, a peripheral neighbourhood The two communities share a religious building in Berlin and have developed a collaboration since 2018. The analysis engages theories of religious place-making and place-sharing (Knott 2005; Zarnow 2018), highlighting the relational dimension of these processes, building on Massey's idea of "space" (1994). Firstly, it illustrates how the encounter and collaboration between the two congregations can help challenge social inequalities or, as Fauser (2024) calls them, internal borders, which hinder migrants' ability to respond to their needs and to access services. In doing so, it emphasises the Eritrean community's proactive role in navigating a challenging environment with limited resources and access to local networks. Secondly, the paper contributes to discussions on (in)visibility and (in)audibility of migrant religious communities (e.g. Garbin 2013; Saint Blancat & Cancellieri 2014; Beekmans 2019), especially as related to their encounters with other religious communities as well as with the wider local society. It specifically highlights the agency of religious communities in these contexts, with an emphasis on postcolonial approaches (Rosello 2001; Nahnfeldt & Rønsdal 2021). Moreover, it thinks through the entanglements between these aspects and the concept of "encounters" (Tweed 1997; Heimbrock and Wyller 2019). Thus, this study provides significant inputs to debates that address the materiality of spatial and religious transformation in multireligious contexts.
