Origin and history

The necropolis of Bois des Géantes, also known as the necropolis of Bois des Joyandes, is a megalithic funeral site located in Bourg-Saint-Andéol, in the department of Ardèche, in the Auvergne-Rhône-Alpes region. It consists of six dolmens spread over about 750 meters, built between 3000-2900 and 2200 BC, during the final Neolithic, Chalcolithic and Bronze Age. These monuments were erected in a natural depression, stabilized by rocky outcrops, and use local materials, including limestone. Their use continued until the recent Bronze, before being abandoned.

The dolmens were first mentioned in 1837 by the Bonnefont surveyor, then studied by prehistorians such as Jules Ollier de Marichard and Léopold Chiron from the second half of the 19th century. Seven dolmens were initially recorded, but only six were confirmed by subsequent research. Ranked historic monuments in 1900 as "Dolmens des Joyandes", these structures illustrate three megalithic architectural types of the Midi: bas-rhodanien, caussenard and Languedocien.

Excavations between the 19th and 21st centuries revealed a variety of funeral furniture, including arrow tips, axes, copper trimmings, and human bones. Dolmens were associated with tumulus of varying sizes, some still intact. The site was also visited and partially looted in the 19th and 20th centuries, as evidenced by modern objects found on site.

The toponym "Bois des Géantes" comes from the local legend evoking giants, a belief shared with other megalithic sites in France. The dolmens were thoroughly restored and studied, particularly in the early 2000s, under the direction of archaeologists like Wolfgang Pape. This research has contributed to a better understanding of their architecture, funerary use, and integration into the geological and cultural landscape of Lower Victoria.

Dolmen No. 1, a Languedocian type, is distinguished by its funeral chamber preceded by an antechamber, a rare feature in the region. Other dolmens, caussenard or bas-rhodanian, have trapezoidal chambers or vestibules. Their construction reflects an adaptation to the local resources and funeral practices of the period, with stone tumulus and sepulchral chambers of various sizes.

Today, the necropolis of the Bois des Géantes is protected and is the subject of development projects by the commune of Bourg-Saint-Andéol. Recent excavations, carried out until 2013, have clarified the chronology of the site and its role in regional megalithism, while highlighting its importance for understanding prehistoric societies in southern France.
