The Amman Citadel is a national historic site at the center of downtown Amman, Jordan. The L-shaped hill is one of the seven jabals that originally made up Amman. Evidence of occupation since the pottery Neolithic period has been found, making it among the world’s oldest continuously inhabited places. The Citadel is considered an important site because it has had a long history of occupation by many great civilizations. Most of the buildings still visible at the site are from the Roman, Byzantine, and Umayyad periods.
