The Old City of Jerusalem and its surrounding walls are a part of the UNESCO World Heritage Site list. With its history and spiritual meaning, the city and its walls represent the heart of the larger city of Jerusalem and most of the holy sites in the area are located within the Old City walls. Jerusalem is sacred to three religions: Christianity, Judaism, and Islam. The sacred site for the Christians is the Church of the Holy Sepulcher, for the Jews it’s the Temple Mount and the holiest site for Muslims is the Dome of the Rock.
You do not need to be religious to be stunned by its history and spiritual value. Go for a walk in the narrow alleyways of the city and experience the many sites and monuments in the area. Every religion has its own sites and due to the size of the area you should have time to visit them all.
