In 2005 the skeleton of a boy with an amber necklace was found near Stonehenge.
Tests have subsequently found that the boy was 3,550 years old and that the boy grew up around the Mediterranean Sea. This was determined after analysis of different forms of the elements oxygen and strontium in his tooth enamel.
Apparently the boy was about 14 or 15 years old and the Amber necklace and the position of the grave next to a Bronze Age burial mound close to Stonehenge indicates that the boy was likely to be of high status.
I find it fascinating that even so long ago people were moving about over so such long distances.
