Jabal al-Qal'a

Jabal al-Qal'a, also called Amman Citadel is a national historic site at the center of downtown Amman, Jordan. Known in Arabic as Jabal al-Qal'a, (جبل القلعة) , the L-shaped hill is one of the seven jabals that originally made up Amman.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 Amman Citadel’s history represents significant civilizations that stretched across continents and prospered for centuries, as one empire gave rise to the next. It also symbolizes the birth of the three great monotheistic religions - Judaism, Christianity and Islam.
