Ancient artificial island found in Scotland, older than Stonehenge

An expedition in Scotland revealed that an artificial island in Loch Bhorgastail was built over 5000 years ago, well before Stonehenge.

The structure, called Lewis, features a crannog—a wooden construction protruding from the water used by Neolithic communities.

The wood and Neolithic ceramics found indicate these islands were constructed between 3800 and 3400 BC, showcasing impressive technical skills for their time.

Researchers employed stereophotogrammetry, a technique combining photographs to create accurate 3D models of both above and below the water surface.

Controlled excavations allowed the team to remove layered wood, pottery, and natural materials, revealing community and ritual activities.

Stephanie Blankshein, leading the team, highlighted that these islands were replicated across Scottish waters, many still unexplored, opening new insights into Neolithic life.

The discovery also shows that these structures were renovated and expanded over different periods, including the Iron Age, possibly serving both residential and ceremonial purposes.

The portable stereophotogrammetry system enabled precise mapping of the submerged structure, integrating terrestrial and underwater data into a single detailed model.

This find confirms that Neolithic communities possessed advanced skills and resources, capable of complex constructions with rudimentary tools, and that these sites held significant cultural value.
