Öz At that part of Samsat which will be summerged by the waters of Atatürk Dam, the excavations under the supervision of Prof.Dr. Nimet Ozgüç on behalf of Lower Euphrates Project have been going on since 1978. I would like to express my sincere thanks to my instruc-tor Prof.Dr. Nimet Ozgüç who gave me the permission to publish some of the findings founded at Samsat, and being one of the members of the staff. Samsat is one of the largest ancient settlements of this region, and consists of a mound and its lower city. The mound has 405-455 m. above sea-level. Excavations are being carried out in large areas at the mound and the lower city. Moreover, trial excavations to establish the thicknesses of cultural layers in these ancient settlement areas have been made on the slopes of the mound.
