The aim of the paper is to analyse the involvement of the local and regional authorities within the Conference on the Future of Europe. The former, being closer to the citizens, could play important role in reaching “every corner of the European Union” and helping the citizens to articulate their ideas about the European integration. Therefore, the activity of the subnational level could contribute to the final success of the Conference (or failure – in case of lack of any actions). The analysis is based on the author’s own empirical study conducted among the Polish territorial self-government units after the closure of the Conference. The local and regional authorities were asked if they informed the citizens about the Conference, organised events regarding this enterprise or took part in the events organised by other entities. The results show very low level of the activity, even among the territorial self-government units that are present at the European level. The conclusions regard both to the Polish circumstances as well as to the general performance of the Conference. In the first case, they unveil the unwritten practice among the Polish territorial self-government units on their involvement in the European affairs. Regarding the second point, the results indicate that the Conference din not manage to exceed the “European bubble”
