Prof. Y. Papadatos (University of Athens) | Wednesday June 14 at 16:00
The archaeological site of Gournia sits on the north coast of the Isthmus of Ierapetra in East Crete. Possessing some 50 well-preserved houses, a system of cobbled streets, a central court, a Minoan palace, and cemetery, Gournia gives the visitor the best picture of what a Late Bronze Age (1500 B.C.) town looked like. Gournia was a regional production center of bronze tools and weapons, domestic objects, and pottery and stone vases, an active trade emporium with overseas connections to other parts of the Aegean and the Near East, and the palatial administrative center for the Mirabello region. Its harbor complex consists of a monumental shipshed, fortification walls with towers, a riverside dam, and a cobbled street running from the coast to Town.
Guided Tour to the Institute for Aegean Prehistory Study Center for East Crete
(in English)
Dr. Tom Brogan (INSTAP) | Wednesday June 14 at 16:00
INSTAP Study Center for East Crete is a unique facility for archaeological research, especially in the area of Aegean Prehistory. The Center is committed to stimulating and facilitating publication in the broader field of Cretan studies, with a focus on archaeology and ethnology. The Center provides storage space for artifacts from American and Greek-American excavations in eastern Crete and offers services for the primary study of excavated material to both member projects and individual scholars. On a broader level, the Center also functions as a base of operations for individuals engaged in a wide range of Cretan research topics unrelated to the member projects. The numerous facilities and services at the Center are available to both individuals and projects.
