The Western Wall (Hebrew: הַכּוֹתֶל הַמַּעֲרָבִי, romanized: HaKotel HaMa'aravi, lit. 'the western wall', is an ancient retaining wall of the built-up hill known to Jews and Christians as the Temple Mount of Jerusalem. Its most famous section, known by the same name, often shortened by Jews to the Kotel or Kosel, is known in the West as the Wailing Wall, and in Islam as the Buraq Wall. In a Jewish religious context, the term Western Wall and its variations is used in the narrow sense, for the section used for Jewish prayer; in its broader sense it refers to the entire 488-metre-long retaining wall on the western side of the Temple Mount.
