An international communication campaign to promote knowledge and dispel fear of the extension of the 25-member European Union: this is summed up by "One More Brick on the Bridge", the scheme that the Acli (Italian Workers Christian Associations) have developed as part of the EU "Prince 2004" scheme, to bring the "old" European countries closer to the 10 "new" ones, which have joined the EU on May 1st 2004. The communication and awareness-raising campaign informed the promoters comes after a survey of the citizens’ reactions to the Euro25 conducted on 4 sample areas of the "old" Europe (Alsace-France, Brandenburg-Germany, Hainaut-Belgium and Friuli Venezia Giulia-Italy). Subjects ranged from immigration to unemployment, from xenophobia to labour cost, also opening optimistic prospects in those who view the extension as an opportunity for cultural enrichment, scientific cooperation and the growth of Europe in the international financial markets. The key points of the campaign are the opening of a multilingual website (www.brickonbridge.acli.it) showing the steps of the scheme and providing access to all produced materials, and the development of a DVD containing experiences of immigrants from the "new" countries who are already perfectly integrated in the social-cultural scene of the old countries.
