A universal story. 4,000 years ago, Jerusalem was a small isolated village, perched on a ridge line between the Mediterranean and the desert. Today, it is an agglomeration of almost a million inhabitants that focuses the eyes and attracts visitors from all over the world. In the meantime, monotheisms were invented there, the greatest conquerors seized it, the greatest empires clashed there. Cradle of Judaism, Christianity and Islam, East Jerusalem is today a spiritual capital for more than half of humanity. Tracing the history of this cradle common also makes it possible to tell differently the history of religious identities.
