From 2007, the team of underwater archaeologists and technicians of the centre Camille Jullian (Aix Marseille University, CNRS) is involved in several research programs in Croatia, in the frame of bilateral scientific collaborations with governmental institutes (University of Zadar, Archaeological Museum of Istria and Croatian Conservation Institute). The Ministry of Culture of the Republic of Croatia and the French Ministry for Foreign Affairs mainly support these researches. The paper will present the data gathered from the study of several shipwrecks dated from the Bronze Age to the Roman era recently excavated in Croatia, in coastal and riverine areas. The study of these shipwrecks sheds a new light in the local shipbuilding practises and gives an insight on the different shipbuilding traditions, which succeeded in the Adriatic and in the adjacent continental regions in the ancient times.
