The Western Wall Tunnel

In 19 BCE, King Herod undertook a project to double the area of the Temple Mount in Jerusalem by incorporating part of the hill on the Northwest. In order to do so, four retaining walls were constructed, and the Temple Mount was expanded on top of them. These retaining walls remained standing, along with the platform itself, after the Temple was destroyed by the Romans in 70 CE.

Since then much of the area next to the walls became covered and built upon. Part of the Western Wall remained exposed after the destruction of the Temple. Since it was the closest area to the Temple’s Holy of Holies that remained accessible, it became a place of Jewish prayer for millennia.

After the Six Day War, the Ministry of Religious Affairs of Israel began the excavations aimed at exposing the continuation of the Western Wall. The excavations lasted almost twenty years and revealed many previously unknown facts about the history and geography of the Temple Mount. The excavations were difficult to conduct, as the tunnels ran below residential neighborhoods constructed on top of ancient structures from the Second Temple Period. The excavations were conducted with the supervision of scientific and rabbinic experts. This was to ensure both the stability of the structures above and to prevent damaging the historic artifacts. In 1988, the Western Wall Heritage Foundation was formed, it took over the excavation, maintenance and renovations of the Western Wall and Western Wall Plaza.

“Warren’s Gate” lies about 150 feet (46 m) into the tunnel. This sealed-off entrance was for hundreds of years a small synagogue called “The Cave”, where the early Muslims allowed the Jews to pray in close proximity to the ruins of the Temple. Rabbi Yehuda Getz built a synagogue just outside the gate, since today it is the closest point a Jew can pray near to the Holy of Holies, assuming it was located at the traditional site under the Dome of the Rock.

he biggest stone in the Western Wall, often called the Western Stone, is also revealed within the tunnel, and ranks as one of the heaviest objects ever lifted by human beings without powered machinery. The stone has a length of 13.6 metres (45 ft), height of 3 metres (9.8 ft), and an estimated width of between 3.5 metres (11 ft) and 4.5 metres (15 ft); estimates place its weight at 570 short tons (520 metric tons).
