In ancient times, the city walls have been used as an important building for military defense, except for the Great Wall of China, more have disappeared. A 7,000-year-old seawall has surfaced off the coast of Israel. The walls are generally used to defend against enemy attacks, and this 7,000-year-old wall is used to defend against the sea.
Many of the flooded ancient villages are located on Israel’s northern coast, where agricultural settlements were scattered in ancient times. They are usually covered in 1 m of sand, protecting the integrity of the ruins but also perfectly hiding their traces. It was not until the storm came that they showed signs that looked like dark spots in the water.
After a winter storm in 2012, Ehud Galilee, an archaeologist at the University of Haifa in Israel, and his team first discovered the 7,000-year-old seawall in an underwater settlement called Tracy, when it was found submerged 90 metres offshore and 4 metres deep.
A storm in 2015 gave them the opportunity to study the ancient village more closely, including the ruins of houses built of stone and wood, livestock bones, hundreds of olive cores, flint tools, a fireplace, and two human tombs. Radioactive carbon detected in the wood and bones of the village dates back about 7,000 years.
The team’s recent article in the Public Library of Science – Synthesis shows that the seawall protecting the village is about 100 meters long and is made up of boulders, some weighing up to 1,000 kilograms, and most likely being moved from 4 kilometers away to the seawall. It is conceivable that people made great efforts to build the seawall.
“We see the same measures we did to deal with sea level rise 7,000, 8,000 years, 9,000 years ago. “It’s an inspiration to us,” said Amy Gussick, an archaeologist at the Los Angeles Museum of Natural History in California. “
