How do we decorate our walls? This exhibition in the Château de Prangins (Swiss National Museum), devoted to the use of wallpaper in interior decoration in Switzerland, traces its evolution from the earliest paper wall coverings of the sixteenthth century to the contemporary creations of artists such as Olivier Mosset and Francis Baudevin. It reveals some previously unseen treasures from the Swiss National Museum’s collection.Divided into eight sections, the exhibition explores the history of a type of decoration that originated in England and achieved its greatest popularity in France from 1780 onwards. There is everything from opulent eighteenth century block prints – some of them bearing the hallmark of the prestigious royal factory Réveillon – to the industrially produced rolls from the late nineteenth century, with their historical or art nouveau motifs. This innovative and interactive exhibition offers opportunities for visitors to experience at first hand the fascinating and unknown world of decorated wallpaper.
