The Cantiere Internazionale d'Arte (International Art Workshop) is an annual international summer school and musical festival for young singers, actors, musicians, conductors and composers. It was set up in Montepulciano, Italy, in 1976 by Hans Werner Henze. Several works received their world premieres at the festival. Productions of concerts and theatre are prepared in the summer school and then played at the festival. Participants do not receive fees, but food and accommodation. Among the venues is the historic Teatro Poliziano.
