The excavation, during the course of which the reservoir was discovered, is part of an archaeological project whereby the entire drainage channel of Jerusalem dating to the Second Temple period is being exposed . The channel runs north along the City of David spur, from the Siloam Pool to a point beneath Robinson’s Arch. The route of the channel was fixed in the center of the main valley that extends from north to south the length of the ancient city, parallel to the Temple Mount. In his description of Jerusalem in the Second Temple period, Josephus refers to the valley by its Greek name “Tyropoeon”, which scholars believe means “Valley of the Cheese-makers”. Another interpretation identifies the valley with the “Valley of the Decision”, mentioned in the Book of Joel.
It became apparent while excavating the channel that during the construction of this enormous engineering enterprise its builders had to remove earlier structures that were situated along the route of the channel and “pass through” existing rock-hewn installations that were located along it. An extraordinary installation that was exposed in recent weeks is a large water reservoir treated with several layers of plaster, which probably dates to the First Temple period.
