Maritime historian Sarah Arenson says, "After he (Prof. Avner Raban) died, I felt it was my duty as a resident of Caesarea and as a colleague of Professor Raban to make his life-work known to the public. I feel, It's the only underwater archaeological park in the world."
Today the land-level archaeological treasures are open to visitors, and are part of the Caesarea National Park, while underwater tours through the remnants of the ancient port are offered by the Caesarea Diving Club.
The diving instructor Mike Green says, "We cover practically all the points you can see on this map, all along the harbour walls. Each point is a point of interest and each point can have some different area of interest to divers."
There are many theories on why Herod's Caesarea port sunk. Some scientists believe it is because the port is located on a geological fault line; other theories point to a series of earthquakes, or even a big tsunami.
