The number of ancient sites to be protected and investigated is very large; the budget never seemed to be large enough, and there were never enough archaeologists to go around. The Archaeological Service accepted assistance from foreign institutions. A French mission had done some excavation for research under the Ottomans. French soldiers in Thessaloniki were glad to assist. The French Archaeological School of Athens had been formed and was active. Johns Hopkins and New York University undertook excavations. The Greek Archaeological Society of Athens and the University of Thessaloniki took a hand. By 1996 there were 25 ephorates of Prehistoric and Classical Archaeology in addition to others on related topics. In 2003 the ephorates were organized into eight directorates. The names and responsibilities of the ephorates require frequent adjustment to support the expanding archaeological investment. The names and numbers of museums also change frequently. Currently many of the artifacts from Halkidiki in general and Ierissos in particular are on display at the Archaeological Museum of Polygyros. Others are to be found in the Archaeological Museum of Thessaloniki.
