Criterion (iv): Erbil Citadel is an imposing example of a multilayered archaeological mound still physically emerging from the surrounding landscape. The wider setting is also important to understand and appreciate Erbil Citadel as a landmark for the city. The authority in charge of its revitalization efforts, the High Commission for Erbil Citadel Revitalization (HCECR), is working in a strategic partnership with UNESCO and other agencies to conserve and rehabilitate the Citadel through programs of physical improvements within the framework of detailed studies and plans that have been the basis for the Conservation and Rehabilitation Master Plan for Erbil Citadel. HCECR action has resulted in the preparation of the Erbil Citadel Management Plan, the instrument that is now regulating all activities concerning the site’s future development and conservation. The buffer areas of the Citadel are not under the responsibility of HCECR, but of Erbil Municipality, which has benefited from UNESCO’s, HCECR’s and international assistance to generate the Urban Design Guidelines for the Buffer Zone of Erbil Citadel, which are under implementation.
