Jerusalem is a city in the Southern Levant, on a plateau in the Judaean Mountains between the Mediterranean and the Dead Sea. It is one of the oldest cities in the world and is considered a holy city to the three major Abrahamic religions: Judaism, Christianity and Islam. Both Israel and Palestine claim Jerusalem as their capital city; Israel maintains its primary governmental institutions there, while Palestine ultimately foresees it as its seat of power. Neither claim is widely recognised internationally.
