Duration: 2006–2009 CICRP programme director: Philippe Bromblet, Jean-Marc Vallet

Partnership(s): University of Venice, Athens Institute of Geology and Mineral Exploration, Historic Monuments Research Laboratory (LRMH), restoration companies Lithos (Italy) and Pons-Asini (Germany), Algerian Ministry of Culture, the Supreme Council of Antiquities, the cultural heritage departments and the universities of Boumerdès (Algeria) and Meknes (Morocco)

From 2006 to mid-2009, the CICRP participated in a European Mediterranean cooperation programme entitled MEDISTONE (preservation of ancient MEDIterranean sites in terms of their ornamental and building STONE). The partners worked on the conservation of three large iconic sites: the ancient cities of Cuicul (Djémila, Algeria) and Volubilis (Morocco) and the stones of the Lighthouse of Alexandria (Egypt) retrieved from the water.

Three lines of research have been pursued: the identification of the origins of the stones used, the assessment of deterioration and the development of a stone reconstruction technique.


This project gave rise to approximately 20 publications and communications. Several students have collaborated and a thesis was defended at the Université des Sciences de Meknès.
