Overlooking the modern city is the Hawler Citadel, or Qalah, which consists of three quarters, Takiya, Topkhana, and Saray. The Qalah was a great Messopotamia city and was a religious center for the Assyrians for a long time. The Assyrians named the goddess Ishtar to watch over the city, and Sennachrib, a great king of Assyria (705-681 BC) had a sophisticated system of aqueducts built to supply the Qalah with water. Currently, the Qalah remains inhabited by Kurdish families, but the government is undertaking an ambitious project to restore and preserve the Qalah's magnificence for future generations. Kurdistan is full of such great archaeological sites having been part of the "Cradle of Civilization." Many of these sites have yet to be fully explored.
