A masterpiece by Biagio Rossetti, the Palazzo dei Diamanti takes its name from its façade of 8 500 diamond-shaped bosses, the asymmetrical layout of which creates a striking optical effect. The building houses the Pinacoteca Nazionale gallery where visitors can trace the development of Ferraran, Emilian and Venetian painting from the 13C to the 18C. Cosimo Tura is of course represented, as are Carpaccio, Ortolano (Deposition) and Garofalo (altarpieces).
