How old are the Carnac stones?
At Carnac, on the south coast of Brittany, lines of granite stones march across the heath for nearly four kilometres. There are three main fields. At Le Ménec about eleven hundred stones stand in eleven rows; Kermario has ten rows; Kerlescan has thirteen shorter rows. In each field the stones are largest at the western end and shrink towards the east, and the rows begin or end at the remains of a stone enclosure.
Around the rows lie burial mounds and chambered tombs, among them the Saint-Michel tumulus and, a few kilometres off at Locmariaquer, a fallen menhir once about twenty metres tall. What the rows were for is not known. Suggestions include processional ways, markers of the dead, and sightlines for the Sun or Moon. None has been demonstrated, and the rows were probably raised in stages by many generations.

What sets Carnac Stones apart
Carnac's rows are a design in gradient. Within each field the stones step down in height from west to east, from blocks taller than a person to stones a child could sit on, and the lines fan slightly as they go. That grading is deliberate. The rows are also only one part of a crowded landscape: the same few kilometres hold great burial mounds whose chambers yielded polished axes of Alpine jade, carried some eight hundred kilometres from their source.
- Place: Carnac, Morbihan, on the south coast of Brittany
- Number: about three thousand standing stones
- Three fields: Le Ménec, Kermario and Kerlescan
- Built: roughly 4600 to 3300 BCE
- Local legend: a Roman legion turned to stone by Saint Cornély
- Nearby giant: the Grand Menhir Brisé at Locmariaquer, once about twenty metres tall
Often mistaken for something else: A stone circle such as Avebury closes a space; the Carnac alignments are open rows that lead the eye and the feet along a line for a kilometre or more.
The story behind Carnac Stones
The monuments of the Carnac district were built between roughly 4600 and 3300 BCE, which makes the oldest of them earlier than Stonehenge by more than a thousand years. A local legend says the stones are a Roman legion turned to rock by Saint Cornély as it pursued him. In the 1870s the Scottish antiquary James Miln excavated there, and his assistant Zacharie Le Rouzic gave decades to restoring the rows. In the 1970s the engineer Alexander Thom proposed that the site was a lunar observatory, a reading most archaeologists do not accept.
Why Carnac Stones matters
Nowhere else did Neolithic people set up so many stones in one design, so Carnac is the measure of what a stone row can be.
How to read Carnac Stones
Archaeologists study it for the beginnings of monument building in Atlantic Europe; visitors walk beside the rows, which are fenced for part of the year to let the ground recover.
Carnac Stones in practice: an example
Walking the length of Le Ménec at dusk, a visitor passes stone after stone for over a kilometre and still cannot see where the lines end.
Where readings of Carnac Stones go wrong
Many stones were re-erected in the nineteenth and twentieth centuries, some out of place, so fine claims about exact alignments need care.
