7000-Year-Old Sunken Discovery Points to European Megalithic Construction Centuries Earlier Than Previously Thought
Off the western coast of France, archaeologists have discovered a sunken granite Mesolithic wall nine meters below sea level, which evidence suggests was constructed close to 7,000 years ago.
The 120-meter-long structure is one of several prehistoric artificial features of its era that have been found in the region, with other similar structures known to exist nearby. The discovery, which was made near Île de Sein in Brittany, was recently detailed in a study that appeared in the International Journal of Nautical Archaeology.
