Menhir d'Er Grah, Neolithic menhir in Locmariaquer, France.
The menhir d'Er Grah stands as a massive stone monument measuring 20.6 meters in height and weighing approximately 280 tons when originally constructed.
Archaeological excavations revealed that this megalith was erected around 5000 BCE as part of a complex structure including 18 additional standing stones in the area.
The stone surface contains ancient engravings depicting tools such as a hatchet-plough, representing the technological capabilities of Neolithic societies in Brittany.
Visitors can examine the four broken sections of the menhir at the archaeological site, which includes information panels explaining its construction and historical context.
The menhir's construction required transportation of orthogneiss stone blocks across 10 to 20 kilometers, likely using rafts through the Gulf of Morbihan.

Throughout France, stone silhouettes still stand in fields, forests, or by the sea. They existed long before villages and roads, witnesses to a world that believed in the sky and hidden forces of the earth. These menhirs, erected over five thousand years ago, in their own way narrate the dawn of civilizations. Some are solitary, others are arranged in rows of hundreds. Some bear engraved faces, others remain silent, smoothed by Breton winds or the rain of the Central Massif. From Carnac to Corsica, from Poitou to the Côtes-d’Armor, these upright stones maintain a strong presence, almost human. Approaching them, one senses the ancient connection between human hands and the memory of the land.
The prehistoric sites of Carnac contain megalithic stones that extend for kilometers. The coastal location features sandy beaches, a marina, and historic buildings. The area includes stone alignments, dolmens, burial mounds, and natural coastal landscapes along the Brittany shore.
