Sentinelles de pierre dressées depuis le Néolithique, les alignements de Pleslin-Trigavou offrent une plongée vertigineuse dans la préhistoire bretonne, au cœur d'un bocage préservé de l'Armor.
History
Lost in the gentle hills of the Penthièvre region, a few kilometres from the Baie de la Fresnaye, the Alignements des Rochers de Pleslin-Trigavou are among the most discreet and authentic megalithic sites in the Côtes-d'Armor. Far from the crowds that flock to Carnac, this site, classified as a Historic Monument since 1889, offers an intimate encounter with Breton prehistory, with no frills and no tourist staging. The upright granite and schist blocks are arranged in rows with a regularity that owes nothing to chance. Their arrangement, characteristic of Armorican alignments, bears witness to a cosmological or ritual intention that archaeologists are still debating: markers of a ceremonial route, solar observatory or funerary markers of a Neolithic territory? The question remains open, and it is precisely this shadowy aspect that gives the site its special magnetism. You can visit the site on foot, taking a slow stroll among the menhirs, some of which have reached a respectable height despite the ravages of time. Direct contact with the stone - its grainy texture, its grey colour streaked with orange and white lichens - establishes a physical and almost intimate link with the Neolithic builders. All around, the Breton bocage creates a setting of hedgerows, sunken lanes and oak trees twisted by the Channel winds. Pleslin-Trigavou is a commune in the historic Penthièvre region, an area of passage between the Armorican interior and the coast. A visit to the Alignements des Rochers reveals the strategic and symbolic importance of these heights to the people who shaped this landscape over five millennia ago. This monument is as much a place for meditation as it is for archaeological exploration.
Architecture
The Alignements des Rochers belong to the family of megalithic monuments known as "alignments", i.e. series of menhirs planted in parallel or slightly converging rows along a precise directional axis. Unlike the dolmen - a covered burial chamber - or the simple isolated menhir, the alignment involves large-scale collective planning, mobilising dozens or even hundreds of individuals to extract, transport and place the blocks. The standing stones at Pleslin-Trigavou are mostly composed of local granite and schist, rocks that are abundant in the pre-Cambrian subsoil of the Côtes-d'Armor. Their shapes are rough, barely roughed-up, with a marked preference for slender silhouettes whose verticality accentuates the symbolic break between earth and sky. Some of the blocks have naturally flat surfaces that the builders were able to exploit to optimise the standing position. The visible heights of the surviving menhirs vary between one and two metres, although the gradual burial by silt and vegetation has reduced the apparent height of several examples. The general orientation of the rows, as with most Armorican alignments, seems to take account of sunrise and sunset at the solstices, suggesting a function as a calendar or ritual marker linked to agricultural cycles. The space between the rows was probably used for processions or collective gatherings, making the alignment an architectural space in its own right: not a closed building, but an open-air architecture that organises the movement of bodies and the view of the landscape.
