Archaeologists have uncovered the wooden foundations of a 5,000-year-old hidden artificial island in a Scottish loch. The island’s impressive architecture has brought the ingenuity of prehistoric people to the forefront. The site, discovered in Loch Vorgastell on the Isle of Lewis, shows that ancient humans were skilled at building such unique islands. At first glance, the small island looks like an ordinary pile of rocks in the water. But when scientists looked closer, they found something else. Beneath the rocks lies a massive circular wooden platform, about 75 feet wide. Prehistoric builders carefully laid logs and stacked brushwood on top to reinforce the foundation.
They built the island about 5,000 years ago during the Neolithic period. About 2,000 years later, it was covered with more rocks. Archaeologists believe that a stone causeway once connected the island to the coast. These artificial islands are known as crannogs. There are hundreds of such islands in Scotland, but many were previously thought to be much older.
But this new discovery proves that some of the islands were first built between 3800 and 3300 BC. People have known about the rocky island for many years, and ancient pottery shards have also been found in the waters around it. The broken pots and jars hint at human activity long ago. But the full story has been difficult to tell, because many of its structures are submerged underwater. To solve this problem, the researchers used a special photographic technique. A diver swam with a special camera to create detailed 3D models of the underwater structures.
Researchers have found that the land and water parts together formed a continuous structure. In addition, radiocarbon dating has revealed the ancient era of woodworking. Its ancient foundations have helped researchers to understand a rare distant past. It was probably an important place for the people who built the island. Found pottery suggests that they gathered here and special events were held here for many centuries.
