Caesarea Aqueduct, view due south from a dune piled up on its side's.
In the attached WS, from the same place a view due north – so by viewing both photos it is possible to comprehend the engineering work done some 2000 years ago by the Romans.
Work begun in the 1st century BC, to provide the ancient town of Caesarea with water supply from Mt. Carmel fountains and springs. Its total length in general is longer than 10 km but it is variable in distances, as it did have diff. sources of water supplies.
2nd WS show another POV of the archs almost hidden by the dunes.
On a side note, those dunes are the most northern dunes in Israel's coastal-plains.
