The Triennale di Milano is an international institution, design museum and theatre that organises conferences, exhibitions and shows about the arts, design, architecture, fashion and cinema. Since its founding in 1923, it has been an icon of cultural and economic life, serving as an engine of international dialogue between society, the arts and industry. The 1933 edition of the Triennale, its preeminent international exhibition, was the first expo recognised by the Bureau International des Expositions (BIE).
