The Achille Castiglioni Foundation was born in January 2011 thanks to the will of the heirs of the artist Achille Castiglioni. The Foundation's main purpose is to share with visitors the projects, drawings, photos and films that have made Achille Castiglioni famous and protagonist in the world of art. Preserving heritage means cataloging it, describing it and sharing it with the widest audience. During the visit the four rooms of the studio are shown: in the first there are the prototypes and the models, in the second the drafting machines and many curiosities, in the third room the anonymous objects that Achille Castiglioni collected during his life and used in the lessons are kept. at the Polytechnic of Turin and Milan. The design is told here by analyzing a wide time span. The Foundation actively collaborates with various Italian cultural realities, but also international ones. In addition, it is home to monographic and interactive exhibitions that revolve around the figure of Achille Castiglioni.
