The Old City is a 0.9 sqm walled area within the modern city of Jerusalem. It is home to several sites of key religious importance: the Temple Mount and its Western Wall for Jews, the Church of the Holy Sepulcher for Christians, and the Dome of the Rock and al-Aqsa Mosque for Muslims. It was added to the UNESCO World Heritage Site List in 1981. Traditionally, the Old City has been divided into four uneven quarters, although the current designations were introduced only in the 19th century. Today, the Old City is roughly divided into the Muslim Quarter, the Christian Quarter, the Jewish Quarter and the Armenian Quarter. Today, Israel controls the entire area, which it considers part of its national capital. In 2010, Jerusalem’s oldest fragment of writings was found outside of the Old City’s walls.
