Dolmen de Crucuno

The Dolmen de Crucuno is a megalithic structure with a rectangular chamber supported by nine upright stones. A massive capstone crowns the structure, creating a tall chamber inside where visitors can stand.

The structure was built during the Neolithic period, around 6000 years ago. The original entrance passage was much longer but suffered partial damage during the 1800s.

The chamber stones bear cup marks carved into their surfaces, revealing ritual practices of prehistoric communities in Brittany. These markings offer insight into the spiritual and daily activities of people who used this place thousands of years ago.

The site is open year-round and accessible without restrictions. It sits within a landscape rich with other megalithic monuments, including the nearby Carnac alignments.

The capstone weighs around 40 tons and rests on the upright chamber stones. This enormous weight demonstrates the careful engineering and planning of the Neolithic builders.
