Divers find submerged Stone Age settlement in Denmark's Bay of Aarhus

Divers have found a submerged Stone Age settlement in Denmark’s Bay of Aarhus, a coastal site dating to about 8,500 years ago that offers a rare glimpse into how Mesolithic communities lived at the edge of a coastline now sunk beneath the sea. The discovery, made about 26 feet below the waves near Denmark’s second-largest city, is part of a cross-border, EU-funded program to chart sunken landscapes across the Baltic and North Seas. The project, which involves researchers in Aarhus, Britain, and Germany, aims to illuminate how ancient populations adapted to rapid sea‑level rise as ice sheets retreated at the end of the last glacial period and to anticipate how rising seas today may reshape coastlines.

Researchers have begun to document an area of roughly 430 square feet (about 40 square meters) for future analysis. Early dives recovered animal bones, stone tools, arrowheads, a seal tooth, and a small worked‑wood fragment. The team is methodically sweeping the seabed with underwater vacuums and indexing finds to reconstruct the settlement’s layout and daily activities. The site’s preservation is unusually intact for an underwater ruin, with well‑preserved wood and other organic...
