Dur-Kurigalzu (modern `Aqar-Qūf عقرقوف in Baghdad Governorate, Iraq) was a city in southern Mesopotamia near the confluence of the Tigris and Diyala rivers about 30 kilometres (19 mi) west of the center of Baghdad. It was founded by a Kassite king of Babylon, Kurigalzu I, some time in the 14th century BC, and was abandoned after the fall of the Kassite dynasty. The prefix Dur- is an Akkadian term meaning "fortress of", while the Kassite royal name Kurigalzu, since it is repeated in the Kassite king list, may have a descriptive meaning as an epithet, such as "herder of the folk (or of the Kassites)". The city contained a ziggurat and temples dedicated to Sumerian gods, as well as a royal palace.
