Have you ever heard about the capital of Gaul? The Alchemists and the Gnostic Christians? Lyon's hidden passageways in France? For many years, Lyon has been famous for its mystical culture, but many of its remaining mysteries are still unknown. Walid Nazim talks about the occult side of Lyon, especially one of its biggest unexplained archeological discoveries: the FishBones, an enormous complex of underground galleries, discovered in the late 50s under the hill of Croix-Rousse, and closed to the public. Nazim’s investigation of these galleries as a significant historical and cultural treasure is the subject of a French documentary. Book-signing at the close of the evening.
