Hezekiah's Pool (Hebrew: בריכת חזקיהו‎, Brikhat Hizkiyahu), or the Patriarch's Pool, located in the Christian Quarter of the Old City of Jerusalem, was once a reservoir forming part of the city's ancient water system.
The pool is believed to be the upper pool referred to in (2Kings 18:17), built by King Hezekiah (f. 700 BC),[1] who met messengers from the king of Assyria there.
