Aven d'Orgnac

The aven d'Orgnac is a cave located to the south of the limestone plateau of the Gorges de l'Ardèche, in the commune of Orgnac-l'Aven in the department of Ardèche, in the region Auvergne-Rhône-Alpes, and Issirac in the Gard department, in the Occitanie region.

Remarkable for the very large volumes of its rooms and its varied Concretions, it was destined for tourism and is now classified a Grand Site de France.

The archaeological site of Orgnac III, occupied since the final Acheulean, is one of the oldest known archaeological sites to have yielded lithic industry using the Levallois technique.
