What is the importance of Jerusalem in the novel, The Lemon Tree?

Jerusalem dates back to ancient times and is considered a holy place for three major religions: Judaism, Islam, and Christianity. According to Jewish tradition, King David made this city the capitol of Israel, and it is where the first temple was built, as well as many other holy sites. For Muslims, it is the site of first Qibla, or focal point for Muslim prayer; it is also where the prophet Muhammad ascended into heaven to speak with God, along with other important holy events throughout history. For Christians, many accounts of Jesus' life occur here, including his crucifixion. For all three religions, followers often make pilgrimage to Jerusalem to see the holy sites. Because so many groups lay claim to it, it is often the site of violent conflict.
