 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.Beyond the northern end of the Western Wall, remains were found of a water channel that originally supplied water to the Temple Mount.The exact source of the channel is unknown, though it passes through an underground pool known as the "Struthion Pool".
