Origin and history

The necropolis of Bois des Géantes, also known as the necropolis of Bois des Joyandes, is a megalithic funerary site located in the commune of Bourg-Saint-Andéol, in the department of Ardèche, in the Auvergne-Rhône-Alpes region. This site, extending about 750 metres, comprises six dolmens distributed in a limestone geological environment. The dolmens were erected between the final Neolithic (ca. 3000-2900 B.C.) and the Ancient Bronze Age, with prolonged use until the recent Bronze. Their location was chosen for its natural stability, thanks to a depression and rocky outcrop, as well as for the availability of stone materials nearby.

The first records of the dolmens of Bourg-Saint-Andéol date back to a search report written in 1837 by Bonnefont, a local geometer. In the 19th century, excavations and studies were conducted by prehistorians such as Jules Ollier de Marichard and Léopold Chiron, who documented the structures and their archaeological furniture. In 1900, the seven dolmen originally identified (including six later identified) were classified as historical monuments under the name "Dolmens des Joyandes". Dolmens have three distinct architectural types: bas-rhodanian, caussenard and Languedocian, reflecting the diversity of megalithic constructions in the Midi de la France.

The site has been the subject of numerous excavation and restoration campaigns, especially in the 20th and 21st centuries. The research revealed various artifacts, such as arrow tips, axes, copper trimmings, and human bones, attesting to its prolonged funeral use. Dolmens are associated with tumulus of varying sizes, and their architecture includes funeral chambers (cella) and, for some, vestibules or antechambers. Dolmen No. 1, a Languedocian type, is distinguished by its size and the presence of an antechamber, while the other dolmens have varied typological characteristics.

The toponym "Bois des Géantes" comes from popular and linguistic interpretations combining megaliths with giants or mythological figures. Variations such as Jayandes or Joyandes have been used in historical publications, reflecting an oral tradition and fascination for these imposing monuments. The site, which has been regularly visited since the 19th century, has also been disrupted by modern developments, such as the construction of a high-voltage line in the 1970s.

Archaeological excavations helped to better understand funeral practices and the spatial organization of the necropolis. Dolmens, built on tumulus, were often surrounded by stone circles or dry stone structures. Their funerary furniture, including bronze, bone and ceramic objects, bears witness to complex rituals and continued occupation over several millennia. Anthropological studies have revealed information on buried populations, although bone remains have often been found fragmented.

Today, the Necropolis of the Giant Wood is protected and is the subject of restoration and enhancement projects. Recent research, carried out under the aegis of the DRAC Auvergne-Rhône-Alpes and the commune of Bourg-Saint-Andéol, has clarified the architectural chronology and characteristics of the dolmens. This site remains a major testimony of the megalithism in Ardèche and Lower Vivarais, illustrating the diversity of the funeral traditions of Neolithic and Bronze Age.
