Reims Cathedral Labyrinth (destroyed) is a labyrinth installation in Marne, Grand Est, France. The design is a medieval reims layout with 11 circuits, 12 walls, approximately 10.3 metres in diameter, built of tile. Documented age: 13th century (destroyed 1779) (~1240 AD). Current condition: destroyed. Installed in the nave of Reims Cathedral — the coronation church of French kings for over 800 years — the original labyrinth was a masterwork destroyed in 1779 by Canon Jacquemart, who found the noise of parishioners walking it during services unbearable. Documentation sources: Saward 2003, Kern 2000. A figure that resolves into a single unbroken line when traced from edge to centre and back.
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.
