Petit Mont, Megalithic cairn in Arzon, France
The Petit Mont structure measures 60 meters in length and 46 meters in width, reaching a height of 6 meters with 10,000 cubic meters of stones.
Built around 4600 BCE, this Neolithic burial monument includes three separate cairns, with additional constructions dating from 3900 BCE and 2700 BCE.
The funerary chambers within the cairn contain numerous artifacts that demonstrate the burial practices and social structures of Neolithic communities in Brittany.
The site opens year-round with guided tours available in multiple languages, educational workshops about archaeology, and combined visits with the Gavrinis cairn.
During World War II, German forces incorporated the ancient megalithic structure into their coastal defense system by building a bunker into the cairn.
