Tumulus d'Er Grah, Neolithic burial mound in Locmariaquer, France
The Er Grah tumulus stretches 140 meters in length and combines stones with earth to form a trapezoidal structure near the Gulf of Morbihan.
Initial excavations in 1908 by Zacharie Le Rouzic revealed a looted funeral chamber, with new investigations in 1991 uncovering dry stone walls.
Archaeological findings from the Italian Alps and Iberian Peninsula demonstrate extensive European trade networks during late prehistoric times.
The monument stands alongside the Table des Marchand dolmen and the Broken Menhir, forming a significant archaeological complex open to visitors.
The structure evolved from a small cairn through multiple construction phases between 4500 and 4000 BCE, gradually extending northward and southward.
