Cathedral Blue (France, Chartres)

During the annual illumination show, the west facade of Chartres Cathedral is illuminated in a deep blue. The great Gothic rose window , a 13th-century masterpiece, becomes the center of a monumental projection where the light rays seem to spring from the stone itself. This architectural mapping is one of the most famous illuminations in France , attracting thousands of visitors and photographers every summer. Located in the Centre-Val de Loire region , Chartres Cathedral is a UNESCO World Heritage Site and remains one of the best-preserved Gothic monuments in Europe.
