Water was taken from Ein Eitam and Solomon's Pools, about 20 kilometers south of Jerusalem crow flies and about 30 meters higher in altitude than the Temple Mount. Like its Hasmonean predecessor, the Aqueduct took a sinuous route in order to bypass ridges lying in its path, although at two locations it was carved as a tunnel: a 400 meters long section under Bethlehem and a 370 meters section under Jabel Mukaber. At Rachel's Tomb the aqueduct split into two, a lower aqueduct running to the Temple Mount and an upper aqueduct leading to the pool near the Herodian Citadel.
