Our collection contains a rich living heritage: the expertise of the artisans who crafted numerous pieces with a quality of workmanship that is no longer available today.

Our master classes, our documentation centre and our internship program work to preserve this valuable expertise and to build bridges between up-and-coming and established designers.
