Ancient island found in Scottish loch

An ancient artificial island, built 5,000 years ago, has been discovered in a Scottish loch. The island, known as a crannog, was previously thought to be from the Iron Age or more recent times, but recent findings show it is far older.

Structure predates Stonehenge

The site contains a massive wooden platform, about 23 meters in diameter, which is at least 5,000 years old. This makes it older than Stonehenge, which was constructed around 3,000 years ago. The platform was later reinforced with stones during the Bronze Age.

Evidence of community life

Archaeologists found hundreds of pottery fragments around the island, some still containing food residues. This suggests the island was used for communal cooking and gatherings, indicating a structured and organized society.

New method for underwater archaeology

The site posed challenges for traditional archaeological methods. Researchers developed a new technique called shallow-water stereophotogrammetry, combining aerial and underwater imaging to create 3D models of the structure. This method is portable, low-cost, and applicable to other submerged sites.

Redefining Scottish prehistory

The discovery changes the understanding of Scotland’s prehistoric artificial islands. Previously, crannogs were thought to be much younger, but this site shows they could be over 5,000 years old. Similar crannogs exist in the Outer Hebrides, and more may be found using the new technique.

Purpose of the island remains unclear

While the island shows signs of communal activity, its exact purpose is still unknown. Researchers suggest it may have been used for rituals, as a residence, or for controlling local resources. The pottery fragments offer clues about daily life, but more research is needed to confirm these hypotheses.
