Résumé en anglais
The shift of borders in Central-Eastern Europe was one of the World War II consequences. Historic Polish heritage was moved on the territories of today’s Lithuania, Byelorussia, and Ukraine while the German one is now within Polish borders. As a result, the historic buildings have for yearsdeteriorated, deprived of their identity and their spirit of the place. Poland’s accession to the EU and the policy of the Ministry of Culture and National Heritage has opened the possibilities of the protection of these monuments. In June 2007, Polish ICOMOS appointed the Committee of Common Heritage. We worked out an original method for the full revitalisation of the threatened common heritage. The consolidation of activities, the coordination of work and fundraising, supported by the management plan for the historical sites as in UNESCO recommendations assure the European level of the project. The sites under the threat are the topic of the present work, the first one is a unique gothic church at Marianka near Pasłęk (Prussich Holland), and other ones were appointed at the 1st international meeting in Lvov in April 2008.
