Coordinates: 31°46′37.83″N 35°13′44.79″E / 31.7771750°N 35.2291083°E Hezekiah's Pool (Hebrew: בריכת חזקיהו, Brikhat Hizkiyahu) located in the Christian Quarter of the Old City of Jerusalem, was once a reservoir forming part of the city's ancient water system. As of 2010[update] the pool is dry and surrounded by buildings on all sides. Flavius Josephus referred to the pool as Amygdalon, meaning ‘almond tree’ in Greek, but it is very likely that he derived the name phonetically from the Hebrew word migdal, meaning "tower", thus it is believed that the original name was Pool of the Tower or Towers.
The pool is supposed to be the one referred to in 2 Kings 18:17, and there is a belief that this is the upper pool where King Hezekiah met messengers from the king of Assyria. At a later time it was fed from the Mamilla Pool, one of the three reservoirs constructed by Herod the Great during the 1st century BCE. by an underground conduit which still partially exists.
