Palazzo dei Diamanti - Pinacoteca Nazionale

Palazzo dei Diamanti is a Renaissance-style palace located on Corso Ercole I d'Este 21 in Ferrara. The main floor of the Palace houses the Pinacoteca Nazionale di Ferrara (National Painting Gallery of Ferrara).To accommodate the growth of Ferrara, in 1492 the Duke Ercole I d'Este demolished the medieval walls of the city on the north, and had the court architect, Biagio Rossetti, design an urban expansion known as the Addizione Erculea. Rosetti was commissioned by Sigismondo d'Este, brother of the Duke Ercole I, to build this palace at the prestigious intersection of what was to be the Decumanus Maximus and Cardo Maximus (Corso Ercole I d'Este) of the "urban addition".
