Jews have prayed at the Western Wall for two thousand years, believing that that spot has greater holiness than any other accessible place on Earth, or the fourth holiest overall, after the Holy of Holies, the rest of the Temple area, and the Courtyard, and that God is nearby listening to their prayers. The tradition of placing prayer written on the small piece of paper into a crack in the Wall goes back thousands of years. Included in the thrice daily Jewish prayers are fervent pleas that God return to the Land of Israel, ingather all the Jewish exiles, rebuild the Third Temple, and bring the messianic era with the arrival of Jewish Messiah (Mashiach).
The Western Wall is holy to the Jewish people because this wall is part of a wall that encompasses the Temple Mount along with the southern and eastern sections. This encompassing wall is thought to be the only remnant of the Temple in Jerusalem and the closest site to the "Holy of Holies", the most holy site in Judaism. Of the three wall sections, eastern, southern and western, the western is the traditional site of prayer.
