flag French archaeologists found a 5,000-year-old underwater wall off Brittany, likely a fish-trap or seawall, revealing early coastal engineering.

flag French marine archaeologists have discovered a 120-meter-long underwater wall off Brittany’s Ile de Sein, dating to around 5,000 BC, the largest submerged structure found in France. flag Built during the Mesolithic or early Neolithic period, it likely served as a fish-trap or protective seawall, featuring large granite monoliths arranged in parallel lines. flag Now nine meters below sea level due to rising waters, the 3,300-ton structure indicates advanced communal planning and engineering. flag The find, revealed through underwater radar and confirmed by dives, may be linked to legends of sunken cities like Ys, offering rare insight into early coastal societies and their response to environmental change.
