Archaeologists have discovered a wall dating from the period of the Second Temple and which was at the southern end of ancient Jerusalem. The wall was built by the Hasmonean kings and was destroyed during the Great Revolt. The remains of a city wall from the Byzantine period (324-640 CE), which was built on top of it, were uncovered in an extensive excavation that is currently underway on Mount Zion. 

The excavation has been in progress for the past year and a half. Plans call for the remains of the ancient city walls to be incorporated in a promenade that will encircle the southern side of Mount Zion and end in the City of David.
