Petit Mont

Petit Mont is a megalithic cairn in Arzon, a large burial structure built from stacked stones during the Neolithic period. The construction reveals multiple inner chambers where early inhabitants placed their dead and left behind various objects.

Construction began around 4600 BCE, making it one of the oldest burial structures in the region. Additions were made over subsequent centuries, showing that the site remained important across different periods.

The name Petit Mont refers to the small hill that the monument creates, showing how Neolithic communities honored their dead through monumental construction. Visitors can observe how the internal chambers were organized and the central role such structures held in their society.

The site is accessible year-round and visitors can explore the exterior and some interior areas. Sturdy footwear is recommended as the paths cross uneven stone terrain.

During World War II, German forces incorporated the ancient structure into coastal defense by building a bunker directly into the stones. Traces of this wartime use remain visible for visitors to see.
