Archaeologists have uncovered a section of a stone-paved street with stairs which connected the Temple Mount
with the Pool of Shiloach (Siloam). The section is about 550 meters south of the Temple Mount, and is believed to be the point at which pilgrims began to ascend by foot to the Temple during Second Temple times (516 BCE - 70 CE).
