Mysterious Artificial Islands in Scotland Are Thousands of Years Older Than We Thought

In the distant past of the northern British Isles, ancient humans didn't always dwell on dry land. Across Scotland, Ireland, and Wales, the foundations of thousands of mysterious artificial islands survive to this day: called crannogs, these strange structures were built long ago by prehistoric hands, in the chilly waters of rivers, lakes, and sea inlets.

Exactly how long ago these things were shaped is something that's never been fully understood. Traditionally, archaeologists estimated Scottish crannogs emerged no earlier than the Iron Age, being first constructed around 800 BCE.

But in more recent years, evidence has come to light that these engineered structures could be much more ancient, and a new study confirms the formations are actually thousands of years older than we realised.

Using radiocarbon dating of four sites located in the Outer Hebrides (the Western Isles of Scotland), researchers have discovered ancient crannogs dating back to 36403360 BCE, meaning early humans were building these giant artificial islands roughly 5,500 years ago, pre-dating even the construction of Stonehenge.
