In the context of Poland’s recent illiberal turn, large cities have been important stages where the fault lines of the national imaginary that run through Polish society have become apparent. In this article, based on ethnographic research in the Polish city of Wroclaw, we focus on individual cultural agents who have engaged with the marginalised Jewish heritage of the city in constructing diverse imaginaries of urban belonging. Their work, carried out against the backdrop of exclusionary nationalist agenda of the Polish state, illuminates the power of human agency to harness cultural heritage as a social and political resource for the present. We show how through their urban-based practices, these cultural agents challenge the Polish hegemonic heritage discourses that exclude the Other from the national imaginary.
