The Carnac Stones

PlacesCarnac, Brittany, France · Raised about 6,000 years agoPurpose debated

Thousands of standing stones march in long rows across the fields of Brittany. Legend says they are Roman soldiers turned to stone.

What was reported

Around the village of Carnac in Brittany, more than 3,000 standing stones stand in long, straight rows stretching for kilometres, along with stone circles and burial mounds. They were raised by Neolithic people between about 4500 and 3300 BCE.

A local legend says they were a Roman army pursuing Saint Cornelius, who turned them to stone, which is why they stand in such perfect ranks.

Explanations offered

Archaeologists agree the stones were set up by Neolithic farming communities, but why remains debated: suggestions include ceremonies, marking territory, honouring ancestors or tracking the sun and seasons. It is one of the largest groups of standing stones in the world.
