Archaeologists reveal secrets of prehistoric human-made island

Phys · · 777 words · By University

Archaeologists from the University of Southampton and the University of Reading have used a new stereophotogrammetry technique to study a prehistoric human-made island, or crannog, in Loch Bhorgastail. Their findings indicate the site was established over 5,000 years ago, predating Stonehenge, and was used for communal activities across several millennia.
