Tell Sheikh Hamad (Arabic: تل الشيخ حمد) is an archeological site in western Syria on the lower Khabur River. It is the site of the ancient Assyrian city of Dūr-Katlimmu, which bore the Aramaic name Magdalu after the fall of the Assyrian Empire (7C BCE). The town may have been founded during the reign of Shalmaneser I and the name Dur-Katlimmu may refer to the limmu (an appointed royal official) Ina-Aššur-šuma-asbat son of Aššur-nadin-šume.
Excavations have recovered 550 cuneiform Akkadian and 40 Aramaic texts belonging to a senior guard of Ashurbanipal.(From Wikipedia). See also: Projekt Ausgrabung in Tall Schech Hamad.
