Sanctuary of the Three Gauls

The architectural complex extended along the southern slope of Croix-Rousse hill, featuring a monumental altar and ceremonial spaces for religious gatherings.

Emperor Augustus established the sanctuary in 12 BCE as a central meeting point for sixty Gallic nations to demonstrate their allegiance to Rome.

The sanctuary served as the location for annual assemblies of Gallic delegates who conducted religious ceremonies and political discussions every August first.

Archaeological remains include substantial masonry walls, marble plates with garlands, inscriptions, and foundations near the current Jardin des Plantes.

The site contained an amphitheater that initially held 1,800 spectators, with stone blocks bearing the names of Gallic representatives carved into the seating areas.
