Ruins of an Aqueduct in Caesarea Maritima
Within Herod's palatial grounds was a very large fresh water pool bordered on one side by a triclinium dining room.
Although the city of Caesarea Maritima was on a large body of water, the Mediterranean Sea, it lacked sources of fresh, drinking water, so it had to be imported. The source was Mt. Carmel's springs, almost 10 miles away. To bring it to the city, Herod built Roman-style aqueducts. Aqueducts were built on an incline so the water could flow down to the place where it was needed.
