This year the old-established Natural Historic Museum Vienna provided the frame for the 15th conference of the German Association for the  Promotion of Underwater Archaeology (DEGUWA e.V.) in collaboration with the Greek Ephorate for Byzantine Antiquities of the Cyclades, the Institute for Byzantine Studies and Modern Greek Language and Literature of the University of Vienna, the Department of Prehistoric and
Medieval Archaeology of the University of Vienna and the Austrian Association for Prehistoric and Protohistoric Archaeology, Research Group for Maritime Archaeology. The topic of the conference " Byzantium at Sea. Innovation and Tradition " was introduced by several national and international lecturers and a survey of the current research could be given.
On the topics of „Byzantium at Sea: Innovation and Tradition“ and „Recent Studies in Underwater Archaeology“ 27 papers were read giving a broad overview over the actual research.
More than 140 guests from 19 countries took part in the conference.
We also had the honor of receiving Mrs. Dörte Lempcke, Dept. of Culture and Protocol of the Ambassy of the Federal Republic of Germans at Vienna, as well as the Consul of the Federal Republic of Germany in Thessaly,  Greece, Mr. Georgios Paparrizos.
In addition, the opportunity was given to participate in guided tours through both the Museum of Natural History and the Museum of Military History at Vienna.
Besides the academic part of the conference very special fringe events were the receptions during the opening of the poster show in the Institute for Byzantine Studies and Modern Greek Language and Literature and in the cupola hall of the Museum for Natural History as well as the dinner in a typical Austrian wine tavern at invitation of the City of Vienna.
