Provenance Research Training Program 
The Provenance Research Training Program (PRTP)
The Provenance Research Training Program (PRTP) is a project of the European Shoah Legacy Institute (ESLI) created by the Czech Ministry of Foreign Affairs in furtherance of the Holocaust Era Assets Conference held in Prague in 2009 and the resulting Terezin Declaration endorsed by 47 countries. The program focuses on provenance research and related issues concerning Nazi-looted art, Judaica, and other cultural property. It provides advanced training to serve the international community of current and future experts engaged in dealing with issues concerning cultural plunder during the Third Reich, the Holocaust and World War II. Each year the program offers week-long workshops that provide an intensive historical overview of cultural plunder—its evolution and implementation; methodological training, including specialized research in public and private archives; a presentation and discussion of legal concepts and instrumentalities at national and international levels, including political, moral and ethical issues and restitution policies and principles. In addition to facilitating research and providing access to a vast array of information, the program will promote the establishment of international networks of provenance researchers that will bring together experts in all relevant fields and countries.
