The RES Series (Reports, Excavations and Studies of the Archaeological Unit of the University G. d'Annunzio of Chieti-Pescara) is dedicated to the projects and the researches of the different teams of the university of Chieti-Pescara working on archaeological projects in Italy and abroad. This first volume is dedicated to the Archaeological Mission in Cyrenaica, starting with the reports and researches of the seasons from 2006 to 2008. Chieti University has been working in Libya with a large international team since 1997. The emphasis of the publication is to present archaeological data to form part of an archive of finds, sites and monuments: a resource and reference point for archaeologists from Libya and elsewhere. At this moment the chora (territory) of Cyrene is facing multiple threats, even the potential loss of important monuments. It is hoped that this publication will contribute to the preservation of the local archaeological heritage.
