This large tumulus is located at the side of the road leading to the village of Le Moustoir. It is 85 metres long, 35 metres wide, and 5-6 metres high, and been a listed historic monument since 1889.
In 1864, after completing his Mané Lud excavations at Locmariaquer, René Galles was looking for another site to excavate to confirm the theories he had developed. He chose the Le Moustoir tumulus at Carnac, and secured the necessary funding for the dig from the Commission de Topographie des Gaules. The excavation brought to light a chamber without a passage to the west, two cists, and a deposit. In the early twentieth century, Zacharie Le Rouzic had certain parts of the monument restored.
René Galles reported that during the excavation, the very slim standing stone almost 2 metres high located on top of the mound toppled. It was re-erected after the excavation. 20 metres to the west, a second menhir, almost 3 metres high, stands next to the tumulus.
