The 2011 field season of the International Umm al-Biyara Project (IUBP) lasted from March 17th to April 14th. The IUBP 2011 was funded by the Council for British Research in the Levant (CBRL), the German Research Foundation (DFG) through the German-French project „Early Petra“ directed by Michel Mouton (Paris) and Stephan G. Schmid (Berlin), the cluster of excellence „Topoi“ (Berlin), Humboldt-University (Berlin) and the Association for the Understanding of Ancient Cultures (AUAC, Basel). We would like to thank the director general of the Department of Antiquities, Prof. Dr. Ziad Al-Saad, for his support and for granting the working permit, as well as Dr. Eimad Hijazeen, commissioner of the Petra Park Authority, for the kind logistic support. We would also like to thank IFPO Amman for lodging the team during its stay in Amman.
