Khaberni - Researchers found a complete stone wall submerged underwater off the coast of Brittany, believed to have been built more than 7000 years ago, specifically around the year 5000 BC.
The ancient archaeological wall stretches 120 meters long, reaches a height of two meters, and is approximately 20 meters wide.
This structure was originally built on land at the western edge of Brittany’s coast, specifically in the area of Sen Island, and today, with the rising sea levels over thousands of years, is located at a depth of nine meters below the water surface.
There is now scientific debate about the original purpose of this massive structure. Some believe it may have been a sea dam or a protective barrier, built in an attempt to fend off rising sea levels, while others speculate that it may have served as a huge fish trap, making it one of the earliest known evidences of organized fishing practices in prehistoric times.
The size and weight of the wall, which is estimated to be about 3300 tons, reflect massive community cooperation. The building technique shows precision and advanced planning, where large megalithic monuments (megaliths) were first placed on the bedrock, then small stones and slabs were piled around them, indicating a highly structured community, whether it was from settled hunter-gatherers or from early Neolithic population groups.
