Les Troyens
Ronconi collaborated with important stage designers, among them Pier Luigi Pizzi ("The Bacchae", "Die Walküre", "Siegfried"), Luciano Damiani ("The Birds", "The Oresteia", "Don Carlos"), and Ezio Frigerio ("Les Troyens"). He also inspired the architect Gae Aulenti to design certain of his productions ("Il viaggio a Reims"). Fashion designer Karl Lagerfeld also created the costumes for some of Ronconi's stagings ("Les Troyens").
