because it is on the northwest edge of the citadel, west of the main gate (Bab Ahmadi), which facilitated the process of finding the historic wall of the citadel. The excavations took place in four seasons 2013-2014-2015 under the chairmanship of Dr. Abdullah Khurshid and many foreign consultants, including Dr. John McCains from Cambridge University in Britain. A part of the citadel wall of Erbil has been discovered, which was not visible, we didn't know much about it only passing references in historical writings, which mentions that the wall was surrounding the citadel, which enabled the inhabitants of the citadel to defend it against the attacks of enemies and invaders. A Neo-Assyrian chamber tomb was found at the foot of the citadel mound during construction activities in 2008. It was subsequently excavated by the local Antiquities Service and archaeologists from the German Archaeological Institute (DAI). The tomb was plundered in antiquity but still contained pottery dating to the 8th and 7th centuries BC. The cooperation between the Antiquities Service and the DAI was continued later that year with a further investigation of the tomb and with a small excavation nearby and geophysical survey of the surrounding area, in which also students from Salahaddin University participated. These investigations revealed the presence of architecture probably dating to the Neo-Assyrian period, as well as more burials belonging to subsequent centuries. In 2007, the Kurdistan Regional Government (KRG) established the High Commission for Erbil Citadel Revitalization (HCECR) to preserve and restore the citadel with the help of UNESCO. Among other things, the HCECR advocates the establishment of a zone extending up to from the citadel in which building height should be restricted to approximately . This would ensure the visual dominance of the citadel over its surroundings. On 2 April 2019, NASA has described the historic citadel as possibly the oldest continuously occupied human settlement on Earth. UNESCO World Heritage status On 8 January 2010, the HCECR and the Iraqi State Board for Antiquities and Heritage (SBAH) submitted the Citadel of Erbil to the Iraqi Tentative List of sites that are considered for nomination as World Heritage Site. The submission states that "The Citadel is today one of the most dramatic and visually exciting cultural sites not only in the Middle East but also in the world." Two further agreements between the HCECR and UNESCO were signed in March 2010, and it was disclosed
