The Old City of Jerusalem is in the heart of the Middle East conflict. Measuring just a single square kilometer, people from three of the world’s great religions rub shoulders in four distinct quarters, and houses built on top of each other nestle against some of the holiest sites in the world. There, of all places, tense co-existence is maintained. In the churches, leaders of the feuding sects stake their religious and territorial claims. On top of the Temple Mount, a group of Palestinian children practice throwing stones, while beneath them an orthodox Jew plans to rebuild the Jewish Temple.
