The Menhir de la Truie, located at the Pointe de Penvins on the public marine estate, not cadastred. It appears on the map and the aerial photographs annexed to the decree: inscription by order of 24 July 2023
Origin and history
The Menhir de la Truie is a megalith located in Sarzeau, Morbihan, England, erected in Neolithic about 6,500 years ago. Originally probably settled on the mainland, it is now located on the estran, at the mouth of the Penerf River, near the Penvins tip. This 4 meters long monolith, lying on a rocky area, is covered by the sea at high tide and is visible only at low tide.
The menhir takes its name from the so-called Truce, where it is located. Its erection dates back to a time when the sea level was lower, and its current location is the result of rising water levels since then. This site illustrates the geological and landscape transformations that have taken place since the Neolithic period, marked by the rise of agricultural communities and the construction of megalithic monuments.
Ranked historic monument by decree of 24 July 2023, the Menhir de la Truie has since 2025 incorporated the buffer zone of the megaliths of Carnac and the banks of the Morbihan, a property registered with the UNESCO World Heritage. This recognition underlines its importance in the Breton megalithic landscape, alongside other emblematic sites such as those of Carnac. The menhir, uncadasterized and located on the public maritime domain, is protected for its archaeological and symbolic value.
