Israel launches world’s first underwater museum

The new underwater museum at Caeserea, a site that has been excavated over the last three decades.It was the largest, most impressive port in the Roman Empire when it was inaugurated in 10 BCE. And some 2,016 years later, the ancient port of Caesarea – along the Mediterranean coast of Israel – was inaugurated again last week, this time as the world’s first underwater museum.
Divers can now don their wet suits and tour the sign-posted remains of the magnificent harbor built by King Herod to honor his Roman patron, Caesar Augustus. The site has been excavated over the last three decades by a team led by the late Prof. Avner Raban of the University of Haifa’s Recanati Institute for Maritime Studies.
It’s not your ordinary museum tour. Visitors float from one ‘exhibit’ to the next, marveling in silence at the untouched remains of a once-glorious harbor: a Roman shipwreck, a ruined lighthouse, an ancient breakwater, the port’s original foundations, anchors, pedestals.
“It’s a truly unique site,” said Sarah Arenson, a University of Haifa maritime historian and participant in the project. “This port was built as the state-of-the-art port of the Roman Empire, and made the other ports of the time, including those of Rome, Alexandria and Piraeus, look small and out-of-date by comparison.”
Arenson notes that the port is also unique today: “There are no other ancient ports in the world that are accessible to ordinary divers,” she told ISRAEL21c. Some such ports are restricted to authorized scientists. Others may be open to any diver, but would be meaningless to such visitors “because,” explains Arenson ,”all you would see is a bunch of stones.”
At Caesarea, divers view some 36 different sign-posted sites along four marked trails in the sunken harbor covering an area of 87,000 sq. yards They are given a water-proof map which describes in detail each of the numbered sites along the way (currently maps are in English and Hebrew; within a few months they will be available in six additional languages.) One trail is also accessible to snorkelers. The others, ranging from 7 to 29 feet below the surface, close to the beach, are appropriate for any beginner diver.
And what does the visitor see?
In a sense, an abrogated history of this once prominent port town – from its entrance at sea (about 350 feet from the current shoreline) to the Roman shipwreck that signaled the demise of the port, probably due to an earthquake, about a century after its construction, researchers believe. And, in between, divers can view the remnants of the original foundations that made this harbor one of the wonders of the Roman Empire.
“This port was built using the knowledge and technology of Roman engineers,” explains University of Haifa maritime historian Dr. Nadav Kashtan, a member of the team that excavated the site.
It was constructed with a type of hydraulic cement, invented by the Romans, known as pozzolana. “The Romans found that when they take the volcanic powder found around Mount Vesuvius and mix it with lime and rubble, the substance hardens in water,” Kashtan told ISRAEL21c.
“This ‘hydraulic concrete’ was imported to Casearea and used to fill wooden frames which were then lowered into the water to lay the foundations for the port.” Two such frames were found, one almost perfectly intact, and are on view today.
Kashtan notes that thousands of men were recruited – both from Rome and locally – to build the port over the course of 12 years. Among them were many divers, who descended simply holding their breath, or possibly in a diving bell.
The Roman city of Caesarea was built on the ruins of a decaying Phoenician town called Straton’s Tower. Its builder, Herod, who also built the Second Temple of Jerusalem, was considered one of the most magnificent builders of the Roman era, notes Kashtan.
The Jewish king built the town – given to him as a present by Augustus – into a grand, fortified city that served as the capital of the Roman province of Judea for about 600 years.
The first century Jewish historian Josephus Flavius described the building of the port of Caesarea in ‘The Jewish Wars’:
“Along the coast Herod discovered a city that was in decay named Straton’s Tower. The stretch of coast-line from Dora to Joppa, between which the city lies, was completely devoid of harbors, so that every ship sailing from Egypt along the coast of Phoenicia had to ride at anchor in open when menaced by southwest wind, for even a moderate breeze from this quarter dashes the wave to such a height against the cliffs that their reflux spread a great commotion far out to sea.”
Researchers note that the excavations correspond closely with Josephus’s detailed accounts of the port.
The underwater park was developed with the financial support of the Caesarea Development Corporation.
Israel has long been known as a diver’s mecca because of the rainbow of corals and exotic fish found off the coast of the Red Sea resort of Eilat. But the country has more than two dozen other diving sites along the Mediterranean coast – from the unique maze of chalky white caves of Rosh Hanikra in the north, to a collection of shipwrecks dotting the coast as far south as Ashkelon.
The sunken port of Caesarea – with its ancient sites and modern explanations – is sure to become one of the top underwater attractions.
