Amiens Cathedral Labyrinth is a labyrinth installation in Somme, Hauts-de-France, France. The design is a medieval chartres layout with 11 circuits, 12 walls, approximately 12.1 metres in diameter, built of tile. Documented age: 1288 AD (restored) (1288 AD). Current condition: restored. The octagonal labyrinth of Amiens Cathedral — 12.1 meters wide, created in 1288 — traces an identical path to Chartres but in an octagonal frame, demonstrating how Gothic master builders transmitted sacred geometric knowledge while varying the container. Documentation sources: Saward 2003, Kern 2000. A pattern with one entrance, one path, and no choices — repeated by unrelated cultures across thousands of years.
The labyrinth is one of several hundred sites of this type catalogued globally; each preserves the same unicursal walking-pattern with regional variation in scale, material, and date.
