The twinning mechanism, which has become very widespread since in Europe since the end of the Second World War, is analysed in this study through its concrete effects on populations and its impact on the sense of belonging to the community of Europeans. The study is based on a questionnaire that was circulated very widely to the local authorities concerned. It provides insights into the spillover effects of the many exchanges that take place as part of twinning schemes and offers some recommendations to reinforce and renew these dynamics.
