法国考古学家在布列塔尼岸外发现一座5 000年之久的水下墙,很可能是捕渔场或海堤,揭示了早期的沿海工程。 French archaeologists found a 5,000-year-old underwater wall off Brittany, likely a fish-trap or seawall, revealing early coastal engineering.

法国海洋考古学家在布列塔尼的Ile de Sein附近发现了一座长达120米长的水下墙, 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. 在梅索利蒂或早期新石化时期建造的,很可能成为渔场或保护性海堤,以平行线排列的大型花岗岩石块为主。 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. 由于水位上升,海平面现在比海平面低9米,3,300吨结构显示社区规划和工程先进。 Now nine meters below sea level due to rising waters, the 3,300-ton structure indicates advanced communal planning and engineering. 通过水下雷达发现并经潜水证实的发现,可能与Ys等沉没城市的传说有关,为早期沿海社会及其对环境变化的反应提供了罕见的洞察力。 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.
