For Jews, Jerusalem is considered the holiest city in the world because it was the center of Jewish religious and national life for thousands of years. The First and Second Temples, which were central to Jewish worship and sacrifice, stood in Jerusalem and the Western Wall, which is considered the last remaining part of the Second Temple, is considered a holy site for Jews.
For Christians, Jerusalem is considered holy because it is the city where Jesus was crucified, buried, and resurrected, according to the New Testament. Many important events in Jesus’ life, such as the Last Supper, also took place in Jerusalem. As a result, Jerusalem is an important site of pilgrimage for Catholics.
In addition to these religious reasons, Jerusalem has also played a significant role in the history and cultural heritage of these monotheistic religions, which has contributed to its status as a holy city. It is considered to be the Mother City of the Church of Jerusalem.
