Right next to the walls of the Old City of Jerusalem is the Biblical Mount Zion. Interestingly, this mountain has changed its place throughout history! First, the Lower East Hill was called Mount Zion, while there was a fortification that King David conquered and built the city of David. Later, when the First Temple was built on the Upper East Hill, this hill was named Mount Zion. Today we know this hill as Temple Mount. The final destination of the name Mount Zion is West Hill. For Christians, this hill is important because the Bible says that the Last Supper and the Dormition took place there. Today, the Abbey of Dormition is standing here. On this hill is the Tomb of David, which is a holy place for Jews.
