“The Low-level Aqueduct is one of two ancient water conduits that originated at the springs in the Hebron Highlands and at Solomon’s Pools, and terminated in Jerusalem and the Temple Mount. We can learn about the construction of the aqueducts and the repairs that were carried out on them from various historical sources which date from as early as the Second Temple period, as well as from later sources. Different sections of the aqueduct’s course were also exposed in archaeological surveys and excavations that were conducted from the middle of the nineteenth century until the present. Research has shown that the ancient aqueduct was meant to supply high quality spring water to the Temple Mount, to Jerusalem’s residents and to the many pilgrims that have come to the city over the course of generations. After the Great Revolt was suppressed and the temple was destroyed, the aqueduct served the Tenth Legion and afterwards Aelia Capitolina, which was Roman Jerusalem. The aqueduct was also used during the period of Christian-Byzantine rule and throughout the years when Muslims governed in Jerusalem.”
