The Ol City (Hebrew: העיר העתיקה ha'ir ha'atika, Arabic: البلدة القديمة AlBalda Al Qadimah) is a 0.9 square kilometre (0.35 square mile) area within the modern city of Jerusalem. Until the 1860s this area constituted the entire city of Jerusalem. The Old City is home to several sites of key religious importance: the Temple Mount and its Western Wall for Jews, the Church of the Holy Sepulchre for Christians, and the Dome of the Rock and al-Aqsa Mosque for Muslims.
