About
About Samsat Höyük Submerged Citadel Approach
Samsat Höyük Submerged Citadel Approach is the drowned approach ramp and lower town of Samosata — capital of Hittite Kummuh and later Commagene Kingdom under Antiochus I. Özgüç excavations before 1989 closure exposed Hittite bronze hoards, Neo-Hittite hieroglyphic Luwian orthostats and the Commagene palace terrace of Mithridates I. The citadel now forms a wooded island 1.2 km offshore in Lake Atatürk; the approach causeway and lower town lie 15–25 m underwater, documented by pre-dam photogrammetry and sonar.
Why it mattersHittite Kummuh to Commagene capital — drowned citadel preserves Hittite–Hellenistic continuity underwater
