Settled more than 6,000 years ago, Erbil Citadel is thought to be one of the longest continuously inhabited sites in the world. The Citadel, which rises some 30 meters above the plain, is surrounded by a lower town that developed in the modern city of Erbil. The Erbil Citadel, locally called Qelat, is a tell or occupied mound, and the historical city centre of Erbil. Over the millennia, the Erbil Citadel has taken shape, each generation building new structures on top of those of the previous generation.
