Jerusalem is the holy city of three Abrahamic religions: Judaism, Christianity, and Islam.
The Western Wall is part of the ancient wall around the western slope of the Temple Mount in the Old City that survived the destruction of the Second Temple. The greatest shrine of Judaism outside the Temple Mount itself, it has for centuries been a symbol of faith and hope for many generations of Jews, a place of pilgrimage and prayer.
Bethlehem is a sacred city for Christians, second in importance to Jerusalem, where, according to the Gospels, Jesus Christ was born. In Bethlehem David was born and anointed for kingship.
