In the heart of inland Brittany, the Pierres Droites of Monteneuf reveal a monumental megalithic sanctuary: more than 420 upright menhirs spread over 7.5 hectares, silent witnesses to a Neolithic civilisation of unsuspected sophistication.
History
Hidden for centuries under the ferns and peat of inland Morbihan, the Pierres Droites site at Monteneuf is one of the most remarkable and least-known megalithic complexes in France. Far from the fame of Carnac, this open-air sanctuary offers a strikingly authentic experience: that of a place restored by the hands of the archaeologists themselves, stone by stone, using techniques close to those used by its builders over five thousand years ago. What sets Monteneuf apart from all the other megalithic sites in France is the extraordinary preservation of the traces of development left by the Neolithic builders. Here, archaeologists have found more than just stones: they have unearthed areas where blocks were extracted, cladding paths and even wooden rails used to transport and erect the menhirs. These technical remains, which are absolutely unique in France, provide a concrete understanding of how prehistoric societies with no metal or wheels were able to erect monoliths weighing several tonnes. The tour unfolds over a vast open space, where lines of upright menhirs dot the moorland landscape like the pages of a text whose meaning still eludes us. Some of the stones, still lying or simply raised, retain the original inclination at which they were placed. Interpretation panels carefully integrated into the landscape guide the visitor without ever breaking the spell of immersion in this land of time. The natural setting reinforces the power of the site: Breton hedged farmland, centuries-old oak trees and wild moorland create a setting that recaptures something of the site's primitive atmosphere. At dawn or dusk, when the Atlantic mist brushes against the grey stones, the Pierres Droites de Monteneuf exude a rare emotion, somewhere between temporal vertigo and mineral beauty. A monument to be discovered away from the crowds, for those who seek depth rather than notoriety.
Architecture
The Pierres Droites site belongs to the large family of megalithic alignments, groups of standing stones - menhirs - arranged in lines or groups according to patterns whose organisation is still debated by researchers. At Monteneuf, the megaliths are mainly carved from local schist and sandstone, hard rocks with bluish or slate-grey reflections that take on an almost black hue in the Breton rain. Their height varies from a few dozen centimetres to over two metres for the most imposing, with some blocks weighing several tonnes. The technical originality of the site lies in the exceptional preservation of the Neolithic site infrastructure. Archaeologists have identified extraction areas where the blocks were detached from the natural rock outcrop by percussion and wedging, as well as traces of cladding tracks - corridors carved into the ground - used to slide the blocks on wooden sledges guided by log rails. These edge-planted slabs, placed along the edges of the tracks, form a remarkably sophisticated handling device, revealing true prehistoric engineering. Over the 7.5 hectare site, the menhirs are arranged in several distinct lines and groups, whose general orientation seems to take account of the natural relief and perhaps solar or lunar landmarks. The gradual restoration of these alignments, carried out with modern equipment but using experimental methods inspired by archaeology, has made it possible to understand the spatial grammar of this monumental complex which, at its height, must have been one of the most spectacular megalithic sanctuaries in Neolithic Armorica.
