 (prominent archaeologists) were called in; it became obvious to them that these steps were likely to have been part of the Second Temple period pool. Excavations commenced and confirmed the initial supposition; the find was formally announced on August 9, 2005 and received substantial international media attention. The pool is less than 70 yards from the edge of the Byzantine reconstruction of a pool previously thought to be the Siloam Pool. This small pool collected some of the water as it emptied there at the southern end of Hezekiah's tunnel. The water continued on through a channel into the recently discovered Pool of Siloam. The source of the water is from the Gihon Spring located at the northern end of Hezekiah's tunnel on the eastern side of the City of David. An ancient pool (Upper Pool) existed near the Gihon Spring but was no longer used after King Hezekiah redirected the waters to the western side of the city.

. There are three sets of five steps, two leading to a platform, before the bottom is reached, and it has been suggested that the steps were designed to accommodate various water levels.

 is not yet understood (as of September 2006); nor is the relationship of this pool to the earlier one (i.e., why it was built when the earlier pool already existed). A portion of this pool remains unexcavated, as the land above it is owned by a nearby Greek Orthodox church and is occupied by an orchard known as the King's Garden (compare ).
