The most celebrated labyrinth in the world, installed between 1215-1221 in the nave of Chartres Cathedral, measures 12.85 meters in diameter with an 11-circuit path stretching 261.5 meters to the center. It is the only undisturbed medieval labyrinth surviving in a cathedral nave — all others were destroyed by clergy annoyed by congregants using them as games. The design's geometry encodes lunar and solar cycles: the path's 112 lunations (semi-circular scallops) match the medieval reckoning of the Easter computus. At 317.67° Giza bearing, Chartres sits on the Paris Basin limestone that amplifies acoustic resonance within the cathedral. The labyrinth's center once held a copper plaque depicting Theseus and the Minotaur — melted down during the Napoleonic Wars.
