The aim of the conference is a historicization of the processes of rediscovery in the recent past. We invite contributions linking the historical dimension in dealing with the Jewish architectural heritage with current developments in this field. The focus will be on the historical, political and cultural preconditions and present processes having an impact on the handling of the Jewish built heritage. The key actors and decision-makers should also be taken into account. Therefore, the connection of the micro and macro levels is indispensable for the understanding of these developments because the impact of local actors and political decisions at the central level are closely interrelated. Global and memory culture trends have also contributed to the interest or disinterest in the respective religious buildings. In addition, transnational networks that influenced the preservation of synagogues will be considered, for example, in the context of the Polish-German dialogue.
