قەلات / قلعه اربيل

The Erbil Citadel, locally called Qelat is a tell or occupied mound, and the historical city centre of Erbil in the Kurdistan Region of Iraq. The citadel has been inscribed on the World Heritage List since 21 June 2014.
The earliest evidence for occupation of the citadel mound dates to the 5th millennium BC, and possibly earlier. It appears for the first time in historical sources in the Ebla tablets around 2,300 BC, and gained particular importance during the Neo-Assyrian period. During the Sassanian period and the Abbasid Caliphate, Erbil was an important centre for Christianity. After the Mongols captured the citadel in 1258, the importance of Erbil declined. During the 20th century, the urban structure was significantly modified, as a result of which a number of houses and public buildings were destroyed. In 2007, the High Commission for Erbil Citadel Revitalization was established to oversee the restoration of the citadel. In the same year, all inhabitants, except one family, were evicted from the citadel as part of a large restoration project.
