JERUSALEM, ISRAEL—Archaeologists from the Israel Antiquities Authority have excavated a section of Jerusalem’s ancient Lower Aqueduct, which was uncovered during the construction of a new sewer line in the Umm Tuba quarter of the city. “The Lower Aqueduct to Jerusalem, which the Hasmonean kings constructed more than 2,000 years ago in order to provide water to Jerusalem, operated intermittently until about 100 years ago,” excavation director Ya’akov Billig said in a press release. The aqueduct began at a spring near Solomon’s Pools and sloped gently downward for more than ten miles along an open channel until the Ottoman period, when a terracotta pipe was installed inside the channel to protect the water as it traveled through the growing city. This section of the aqueduct has been preserved for future generations. To read more about ancient aqueducts, go to "Rome's Lost Aqueduct."
