The walled area of Jerusalem, which constituted the entire city until the 1860s, is now called the Old City, and was added to the List of World Heritage Sites in danger in 1982. The Old City has been traditionally divided into four quarters, although the names used today—the Armenian, Christian, Jewish, and Muslim Quarters—were only introduced in the early 19th century. Despite having an area of only 0.9 square kilometer (0.35 square mile), 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.
Modern Jerusalem has grown up around the Old City, with its civic and cultural hub extending westward toward Israel's urban center in Gush Dan. The Arab population resides in clusters in the North, East and South. Today, Jerusalem remains a bone of contention in the Israeli-Palestinian conflict: Israel's annexation of East Jerusalem (captured in the 1967 Six-Day War) has been particularly controversial, as Palestinians view this part of the city as the capital of a potential Palestinian state. The status of a "united Jerusalem" as Israel's "eternal capital" has not been officially recognized by most of the international community, and nearly all countries maintain their embassies in Tel Aviv.
