Bilgroix gallery grave

Bilgroix gallery grave is a prehistoric burial chamber in Arzon made of stone walls supporting large capstones. A passage leads through the structure to the burial chamber, with the western end sealed by an upright stone slab and the floor lined with paving stones.

The structure was built during the Neolithic period around 2900 to 2500 BC as a megalithic burial site in Brittany. Archaeological finds including pottery vessels and flint tools from the region confirm its use as a place for the dead.

The gallery grave shows how Neolithic communities honored their dead and organized burial rituals in their society. The way the stones are arranged reveals what people valued and knew about construction during that era.

The burial site is freely accessible throughout the year in a rural setting, making it easy to visit at any time. Parking is available nearby, and the location is straightforward to reach for anyone interested in exploring prehistoric monuments.

Adjacent to the gallery grave are additional stone walls that may have served defensive purposes, suggesting the site held special importance for the community. Traces of wooden posts indicate that wooden structures once stood alongside the stone chamber, revealing a more complex use of the space.
