Carnac Alignments (Alignements de Carnac)

The Carnac alignments run in long ranks across the heath east and west of the town of Carnac: at Menec, Kermario, and Kerlescan, thousands of granite menhirs stand in parallel rows spanning roughly four kilometers, part of a megalithic landscape that also takes in dolmens, tumulus tombs, and the great broken menhirs at neighboring Locmariaquer. The stones were erected during the Neolithic, probably around 3300 BC with some possibly older, by the pre-Celtic peoples of Brittany, and their purpose is genuinely unknown; the rows' geometry has invited everything from astronomical calendars to processional ways, and the honest entry keeps the purpose an open question. Folklore filled the gap for centuries, with Breton legend making the rows a Roman legion turned to stone by Merlin, and the BBC's A History of Ancient Britain has argued, against the majority view, for Mesolithic hunter-gatherer builders; both claims belong in the entry as claims, attributed. In 2025 the site gained UNESCO World Heritage status as part of the Megaliths of Carnac and the shores of Morbihan listing.

Since 1992, walking freely among the alignments has not been permitted: the state heritage operator runs the interior on guided tours, at 13 euros for adults (6 euros for ages 7-17 and reduced categories, free under 7), departing from the Maison des Megalithes, while a free perimeter path circles the sites and some sectors open to free public access from October through March. That arrangement is itself part of the entry's cultural content: the rows were damaged by centuries of removal and casual use before protection arrived, and Brittany's management of the stones has been publicly contested. Druid revival groups have long claimed ceremonial association with Carnac; this entry describes that as a modern revival relationship, attributed and flagged, distinct from the unknown builders.

Visiting

The Centre des monuments nationaux runs the access: guided tours from the Maison des Megalithes (13 EUR adults, 6 EUR ages 7-17 and reduced, free under 7; groups 200 EUR plus 5 EUR per person), booked online or at the ticket office; free perimeter path, with the municipal car park 900 meters north of the Menec alignments; some sites free-access October through March. Maison des Megalithes hours run per season (9:30-6 spring and autumn, 9:30-7 in July-August, 10-13 and 14-17 October to March, closed January 1, May 1, December 25). The Megaliths Pass covers Carnac, Locmariaquer, the Carnac prehistory museum, Gavrinis, and Petit-Mont.
