Why is the cathedral of Metz nicknamed the « Lantern of the Good God » ? This summer, the exhibition Flashes of Light invites you to discover the multiple facets of light that make this exceptional monument famous. Through a journey of 15 panels, explore the architecture, stained glass, stone, liturgy, and events that showcase this unique heritage, such as the Constellations of Metz festival.
To extend the visit, the Workshops of Graoully offer fun and creative free activities for both young and old, to discover the cathedral in a different way.
