This year, 2025, the Soissons en Lumières event features a spectacular new site: the chevet of Saint-Gervais-et-Saint-Protais Cathedral. Since July 4, the rear facade of the building has been transformed every evening into a veritable illuminated history book. At nightfall, visitors are invited to relive the cathedral’s heyday, from its construction in 1176 to its modern reconstructions.

This monumental video mapping by Ikoï Studio brings the eventful history of this Gothic gem to life. From its Merovingian foundations to the revolutionary period, from the Huguenot ransackings to its incredible conversion into a clothing store for the army, the monument reveals its secrets, brought to life by a moving and informative light show. Thanks to a clever mix of 2D and 3D animations and an original musical score, the show immerses the audience in the heart of the upheavals that shaped the cathedral.
