Grotte Cosquer | Marseille, France

In Marseille, the Grotte Cosquer replica takes visitors 37 metres below sea level -- without getting wet. To fully convey this prehistoric art experience, the Villa Mediterranee chose the Sycomore Medallion, an immersive audioguide designed for a sensory experience.

Worn around the neck and connected to a headset, the Medallion delivers spatialised sound that recreates the cave atmosphere: water sounds, echoes, murmurs -- all automatically synchronised via 16 infrared zones along the route.

This hands-free technology, coordinated with the automated vehicles, delivers precise narration without any manual operation. Each visitor experiences a smooth, intimate exploration faithful to the original atmosphere.

With over 1.4 million visitors served, the Medallion has proven to be an effective solution for making prehistoric heritage accessible and engaging.
