In 1972, the Polish-Egyptian Group for the Restoration of Islamic Monuments was created. It was composed of specialists from several institutions, including the Polish Centre of Mediterranean Archaeology University of Warsaw and the Institute of Mediterranean and Oriental Cultures, Polish Academy of Sciences. "The work on the site included archaeological excavations of grave chambers and foundations, anthropological research, architectural and conservation works, as well as historical studies, for example of the 16th-century donation deed of emir Qurqumas (hogga)". As a result of these works, which lasted until 2000, a protected antiquities zone was established around the complex which also includes the funerary complex of the sultan Inal.
