Atlantic Neolithic: alignments, dolmens and coastal tumuli
You are a field archaeologist, dispatched to Carnac, France, in 2024, to follow up on the enigmatic findings from Bettina Schulz Paulsson's 201
Follow the footsteps of Neolithic builders who erected over 1000 menhirs across 4 km between 4500 and 3500 BC.
« Breton megaliths constitute the epicenter of European megalithic diffusion. »— Bettina Schulz Paulsson, archaeological study, 2019
The story that haunts this land
Carnac welcomes you with its Ménec and Kermario alignments, over 1000 menhirs oriented northwest-southeast across 4 kilometers. These stones erected between 4500 and 3500 BC mark the peak of middle Neolithic in Brittany. Alexandre Collins, their discoverer in 1796, never imagined revealing one of Europe's vastest megalithic ensembles. You walk alongside these granite giants on marked paths, each block witnessing a civilization that already mastered astronomy and collective organization.
At Locmariaquer, the megalithic site confronts you with the Table des Marchands, a passage dolmen dated around 4700-4300 BC, and the broken Grand Menhir. This original stele of 20.6 meters weighed 347 tons before its fall in final Neolithic. The site combines dolmen, menhir and engravings in typical Atlantic funerary architecture. Its sculpted orthostats reveal beliefs of a society already erecting monuments taller than our modern buildings.
The Pierres Plates dolmen immerses you in Neolithic burial chamber intimacy. This passage structure, initially covered by a tumulus, served as collective burial between 4500 and 2500 BC near Carnac. Its orthostats and capstone illustrate architectural mastery of Breton megalithic builders. You enter these millennial tombs where elites of a civilization preceding us by 60 centuries rested.
Erdeven alignments extend your journey with about 3000 blocks erected over 10 kilometers at Plasker. Dated between 4600 and 4300 BC, they rank among Western Europe's oldest. This continuous coastal axis between Carnac and Quiberon witnesses intensive Neolithic occupation of Morbihan. Mané-Lud and Mané-Rutual tumuli complete this landscape of mounds covering dolmens and burial chambers.
Your route ends at Quiberon bay coastal viewpoints, where isolated menhirs punctuate the coastline since Neolithic. These stones erected between 4500 and 2500 BC integrate into Erdeven and peninsula landscape, witnesses of Atlantic megalithic diffusion around 4300 BC. You leave with vision of prehistoric Brittany where each horizon reveals traces of a civilization that shaped Western Europe for two millennia.
