Dating to 1385, the Este's 14th-century pleasure palace suffered significant earthquake damage in May 2012, but its highlight – the Salone dei Mesi (Room of the Months) – remains open to visitors. Inside you'll find Ferrara's most famous frescoes, executed by Francesco del Cossa in 1470, which depict the months, seasons and signs of the zodiac and constitute an exceptionally fine and cohesive example of secular Renaissance art.
Covered by the same ticket is the nearby Museo Lapidario , with its small collection of Roman and Etruscan stele, tombs and inscriptions.
