In a broader sense, "Western Wall" can refer to the entire retaining wall on the western side of the Temple Mount. The classic portion now faces a large plaza in the Jewish Quarter, near the southwestern corner of the Temple Mount, while the rest of the wall is concealed behind structures in the Muslim Quarter, with the small exception of an section, the so-called Little Western Wall. The segment of the western retaining wall traditionally used for Jewish liturgy, known as the "Western Wall" or "Wailing Wall", derives its particular importance to it having never been fully obscured by medieval buildings, and displaying much more of the original Herodian stonework than the "Little Western Wall". In religious terms, the "Little Western Wall" is presumed to be even closer to the Holy of Holies and thus to the "presence of God" (Shechina), and the underground Warren's Gate, which has been out of reach for Jews from the 12th century till its partial excavation in the 20th century, even more so.
