The tunnel exposes 300 m of the wall's total 445 m, revealing the construction methods and the various activities in the vicinity of the Temple Mount. The excavations included many archaeological finds along the way, including discoveries from the Herodian period (streets, monumental masonry), sections of a reconstruction of the Western Wall dating to the Umayyad period, and various structures dating to the Ayyubid, Mamluke and Hasmonean periods constructed to support buildings in the vicinity of the Temple Mount.
