Palazzo dei Diamanti is an exhibition space owned by the Municipality of Ferrara used for important exhibitions of international importance aimed at continuing the great historical-artistic tradition of the city. The exhibitions are organized in collaboration with the Ferrara Arte Foundation, the Modern and Contemporary Art Galleries of Ferrara and the Cultural Activities Sector of the Municipality of Ferrara.

So called thanks to the very particular shape of the more than 8,500 blocks of marble that make up its rustication, the Palazzo dei Diamanti is one of the most famous Renaissance buildings in the world . Designed by Biagio Rossetti, the palace was built on behalf of Sigismondo d'Este, brother of Duke Ercole I d'Este , starting in 1493, and constitutes the ideal center of the so-called "Addizione Erculea", a real doubling of the city which Rossetti conceived for the duke.
