outcrop in the Dome of the Rock is the Foundation Stone, some rabbis say it is located directly opposite the exposed section of the Western Wall, near the El-kas fountain. This spot was the site of the Holy of Holies when the Temple stood. Part of the Temple proper Rabbinic tradition teaches that the western wall was built upon foundations laid by the biblical King Solomon from the time of the First Temple. Some medieval rabbis claimed that today's Western Wall is a surviving wall of the Temple itself and cautioned Jews from approaching it, lest they enter the Temple precincts in a state of impurity. Many contemporary rabbis believe that the rabbinic traditions were made in reference to the Temple Mount's Western Wall, which accordingly endows the Wall with inherent holiness. Divine custody A 7th-century Midrash refers to a western wall of the Temple which "would never be destroyed", and a 6th-century Midrash mentions how Rome was unable to topple the western wall due to the Divine oath promising its eternal survival. Divine Presence An 11th-century Midrash quotes a 4th-century scholar: "Rav Acha said that the Divine Presence has never departed from the Western Wall", and the Zohar (13th century) similarly writes that "the Divine Presence rests upon the Western Wall". Eighteenth-century scholar Jonathan Eybeschutz writes that "after the destruction of the Temple, God removed His Presence from His sanctuary and placed it upon the Western Wall where it remains in its holiness and honour". It is told that great Jewish sages, including Isaac Luria and the Radvaz, experienced a revelation of the Divine Presence at the wall. Kabbalah of the word kotel Rabbi Zvi Hirsch Kaindenover discusses the mystical aspect of the Hebrew word kotel when discussing the significance of praying against a wall. He cites the Zohar which writes that the word kotel, meaning wall, is made up of two parts: "Ko", which has the numerical value of God's name, and "Tel", meaning mount, which refers to the Temple and its Western Wall. Ritual Status as a synagogue Many contemporary Orthodox scholars rule that the area in front of the Wall has the status of a synagogue and must be treated with due respect. This is the view upheld by the authority in charge of the wall. As such, men and married women are expected to cover their heads upon approaching the Wall, and to dress appropriately.
