The present article explores this issue in Luxembourg,a small metropolitan state characterised by the co-presence of largenational groups coming from other European member-states. The objec-tive of the quantitative research is tofind out if the practices of perform-ing arts in this multi-national and urban society is linked to a Europeanintegration approached in terms of cross-national friendship networksand cross-border spatial mobility. The results show that some culturalpractices and social groups are related to different types of cross-national ties and mobility lifestyles securing an EU integrative process.
