King Herod built the first aqueducts to supply water to coastal town of Caesarea. Water was brought from the springs in the foothills of the Carmel to the coastal town via a 8-10 mile aqueduct. As Caesarea's population grew Emporer Hadrian added a second Aqueduct. Eventually two more aqueducts were added. Caesarea is located between Tel Aviv and Haifa. The aqueduct I photographed below is part of the remains of the Roman aqueduct.
