Inside the Pyramid, in the heart of his Labyrinth, Franco Maria Ricci has created a chapel as a symbol of Faith. The floor reproduces an ancient single-path labyrinth already used in many ancient medieval churches throughout Europe. One of the best-known examples of this tradition is the labyrinth decorating the floor in Chartres cathedral: it features eleven circuits, and worshippers would once follow them on their knees whilst praying and singing, as an act of penitence.
