Carnac alignments

Extending for a total of 4km, the Carnac alignments include some 2800 menhirs, forming one of the most iconic megalithic collections in Western Europe.

The Carnac alignments include four sets of rows of standing stones – the Ménec, Kermario, Le Manio and Kerlescan sites – plus Petit Ménec in the municipality of La Trinité sur Mer. 

They were erected between the fifth and third millennium BC. Each site is formed by between ten and as many as thirteen sub-parallel lines of menhirs. The western ends of the Kerlescan and Le Méhec sites comprise a megalithic enclosure: this is oval-shaped at Le Ménec and rectangular at Kerlescan. The Le Ménec site appears to have a second enclosure at its eastern end.

The alignments have been carefully laid out: the largest, most imposing stones lie at the western end of each of the monuments, at slightly higher elevations.

A number of megaliths outside or inside the lines of standing stones (e.g. at the Kerlescan mound, Ménec eastern enclosure, Kermario dolmen, Manio Giant, Kercado tumulus, Kerlescan circle, etc.), illustrate the complexity and timescale of these forms of architecture.

All these sites belong to and are run by Centre des Monuments Nationaux. For opening times for free visits and guided tours, visit
