Religious diversity is posing new and urgent challenges to local authorities and there is no solid foundation of expertise in dealing with this issue at the local level. In some European cities, interfaith platforms are providing local authorities with new governance tools to cope with the challenges of religious diversity and are generating new ways of framing and representing religion in the public sphere. The author takes the city of Barcelona as a case study with the aim of exploring the emergence of a new model for dealing with religious minority issues that goes beyond State–Church relations and the political legacies in this area.

In recent years, the growth and expansion of interreligious initiatives have received increasing scholarly attention worldwide, and interreligious actors and repertoires are gaining relevance within emerging governance regimes of religious diversity in Europe and beyond. However, empirical research in this field is still very limited. With the aim to fill this gap, this special issue gathers four original contributions aimed at critically describing, understanding and reflecting upon the rise of the ‘interreligious sector’ and its growing relevance to the governance of religious diversity in contemporary Europe.
