Three gallery dolmens nestling on the Erdeven moors: monumental Neolithic burial sites that bear witness to the mastery of building and the cult of the dead of the first Breton farmers over 5,000 years ago.
History
In the heart of the Auray region, in the commune of Erdeven, the Mané-Bras site brings together three remarkably well-preserved gallery dolmens, forming one of the most significant megalithic complexes in Morbihan. In a department already exceptional for the density of its prehistoric monuments - Carnac, Locmariaquer, Gavrinis - these collective burials stand out for their meticulous architecture and the coherence of their placement in the landscape. Each of the three buildings follows the logic typical of Armorican covered walkways: an elongated burial chamber, covered with massive slabs, preceded by a narrower access corridor. The whole structure reveals a deliberate architectural intention, far from a crude pile of stones. The Neolithic builders selected and squared blocks of local granite, then erected them and topped them with roofing slabs weighing up to several tonnes. This technical feat, achieved without the use of metal or machinery, is still admired by archaeologists today. Visiting Mané-Bras is like immersing yourself in a dizzying time. The site is set in a landscape of hedged farmland and heather moorland typical of the Morbihan coast, just a few kilometres from the alignments at Carnac. This proximity is not accidental: between 4500 and 2500 BC, this entire coastal fringe formed a vast ritual and funerary space of fascinating geographical coherence. The peace and quiet of the site, far from the crowds that converge on Carnac, allows intimate contemplation of the structures. The stones with their patina of orange and grey lichen, the short grass swept by the breeze from the nearby Atlantic, the low-angled evening light cutting into the crevices of the granite: Mané-Bras offers a sensory experience that prehistory enthusiasts and heritage photographers instinctively seek out. Listed as a Historic Monument since 1921, the site benefits from long-standing protection and regular maintenance to ensure that the structures are accessible and legible to all visitors, from families to specialist researchers.
Architecture
The three gallery dolmens at Mané-Bras belong to the architectural type known as the "Armorican covered alley", characteristic of the Middle and Late Neolithic of the Armorican Massif. Each structure consists of a relatively narrow access corridor, set between two rows of orthostats - large slabs standing vertically - which leads to a main burial chamber that is slightly wider and higher. The whole structure is covered with horizontal granite slabs, the thickness and weight of which give the monuments their distinctive massive, squat silhouette. The materials used are exclusively local: Morbihan granite, quarried from outcrops on the surrounding moorland or coastal banks, is exceptionally resistant to atmospheric agents. Its bluish grey colour, dotted with feldspar and quartz, takes on warm reflections in the light of the setting sun. The roofing slabs, some of which can be four or five metres long and weigh several tonnes, were laid without the use of binders or mortar, their stability relying solely on the precision of the wedging and the balance of the masses. The orientation of the access corridors, often facing the rising sun or south-east in Morbihan monuments, suggests an astronomical or symbolic intention linked to the rising sun, in keeping with Neolithic funerary rites that associated death and solar rebirth. The layout of the three structures on the Mané-Bras site, their spacing and relative orientation, suggest an overall design rather than a chance accumulation, characteristic of a society capable of planning a cult space over the long term.
