A historical formation located in the depths of Loch Bhorgastell provides information about human existence more than 5,000 years ago. This structure, which nowadays appears to be a small island made of stone, used to be a wooden structure carefully built by Neolithic people. The age of this ancient structure makes it older than other famous sites like Stonehenge. This structure challenges traditional views of the engineering skills and settlements of early societies.When seen from outside this structure does not appear to be anything extraordinary. Yet, beneath the surface lies evidence of the meticulous nature of its construction, multiple uses throughout history, and changes throughout the prehistoric era. According to archaeologists, this structure is the best example of human ability to shape the environment in ancient times.

Scientists discover a lost Scottish island created by humans 5,000 years ago

This particular site is of the type called a crannog, which can be described as a man-made island in lakes and wetlands. Crannogs were mostly associated with the Iron Age and later periods. However, recent discoveries indicate that there may have been some crannogs that appeared in an earlier period.According to the study conducted by experts from the University of Southampton and the University of Reading, this particular crannog was built between approximately 3800 and 3300 BC. This means that its building dates back to the Neolithic period when Stonehenge was not even built.As preliminary analysis has shown, the crannog initially consisted of a round-shaped wooden platform approximately 23 meters in diameter. Its construction consisted of several layers of timber, brushwood and stones, which were used to secure the foundation of the island. Later, the island was expanded and improved. Evidence of constructions that took place during the Bronze Age and then the Iron Age has been discovered.

What do pottery fragments tell us about Neolithic activity at the lake

Archaeological surveys have uncovered large quantities of Neolithic pottery fragments around the site. Some of these pots have traces of food residue, indicating cooking or food preparation activities.This description changes the way the site is interpreted. It may not have been entirely symbolic or defensive. Instead, it may have served as a gathering place where people met, shared food, and carried out communal activities. Experts suggest that it may have had both practical and social significance.The idea of ​​people building and using a wooden island in the middle of a lake seems unusual today. Yet in the Neolithic world, such places would have created a sense of isolation from everyday land-based life. Water boundaries often held meaning in ancient cultures, possibly marking transitions between different social or ritual realms.Still, much of this remains speculation. The evidence provides clues, but not complete answers.

How scientists discovered a hidden passage to the crannog

Among the most interesting discoveries are the underground stone passageways connecting the island to the mainland. These indicate that initially, there may have been some easy and perhaps even managed access to the island.Throughout the millennium of water level fluctuations, part of the structure would have been flooded, thus breaking apart what was previously a contiguous landscape.Investigating such landscapes has its own challenges, one of which arises from the fact that between dry land and deep water there is an area where traditional land-based surveys cannot be conducted, and underwater methods are also not efficient enough.To address this, the scientists combined underwater photography, photogrammetry using drones, and GPS measurements to overcome the shortcomings of the individual techniques and produce an accurate 3D reconstruction of the area, including both dry land and submerged portions.
