By matching the chemical finger prints of their stone samples they have proven the origin of stones used to build parts of Stonehenge.

In a picturesque and quiet corner of West Wales called Pont Saesnon is a rocky outcrop that looks like any other in this mountainous country.

But thousands of years ago it provided the building blocks for the ancient structure of Stonehenge that still captivates people today.

It's now thought the stones took an alternative route and travelled ten miles west to the natural harbors that dot the Welsh coastline then shipped to their final resting place on Salisbury Plain, in England. This theory now needs to be tested by archaeologists.

These new discoveries bring people who are fascinated with Stonehenge one step closer to unlocking its mysteries.
