It is a conical shaped structure built of boulders, roughly 230 feet in diameter, 30 feet high and weighing an estimated 60,000-tons, 40 feet underwater in the Sea of Galilee. And archaeologists have no idea what it is. Based on the build up of sediment, it is between 2,000 and 12,000 years old, which is too wide a range to help identify it. It’s not even clear if the structure was built on land when the sea levels were lower, or if it was constructed underwater. The structure was located in 2003 by sonar scan. Now ten years later, researchers from the Israel Antiquities Authority are mounted an expedition to attempt to learn more about the unexpected mound of boulders, which they speculate could have been a burial site, a place of worship or even a fish nursery.
