The Milan Triennial, an international exhibition of art and design, was held at the museum thirteen times between 1936 and 1996, and – after a break of twenty years – again in 2016.
Since 2003 the Triennale has awarded the triennial Gold Medal for Italian Architecture (Italian: Medaglia d'oro all'architettura italiana).
