Ferrara owes its shape to a single Renaissance decision. In 1492 Duke Ercole I d’Este had the architect Biagio Rossetti lay out a grid of wide straight boulevards north of the medieval town before a single palace stood on them, doubling the city overnight. That plan survives intact alongside the moated Castello Estense and the diamond-cut Palazzo dei Diamanti.
At a glance
Ferrara was ruled by the Este family from 1240 to 1598, a dynasty whose court supported some of the most read literature of the Italian Renaissance. Matteo Boiardo began the chivalric epic tradition here with his “Orlando Innamorato” in 1483, and Ludovico Ariosto, working as court secretary to Cardinal Ippolito d’Este, continued it with “Orlando Furioso” in 1516. Giovanni Battista Guarini’s pastoral drama “Il Pastor Fido” followed in 1590. The Dominican friar Girolamo Savonarola was born and educated in Ferrara, though his later career belonged to Florence.
The city’s other great legacy is urban rather than literary: the Addizione Erculea, the 1492 extension designed by Biagio Rossetti for Duke Ercole I, which set out broad straight boulevards on a rectangular grid before construction began, doubling the area of the city.

History
The Castello Estense was begun in 1385 on the direct order of Niccolò II d’Este, immediately after his forces put down a popular revolt against the taxes he had imposed. The moat, the drawbridges and the four corner towers were designed to defend the ruling family against its own citizens rather than against an outside army.
The castle’s grimmest chapter came in 1425, when Niccolò III d’Este discovered that his wife Parisina Malatesta was having an affair with his illegitimate son Ugo. Both were beheaded in the castle’s dungeons, in a room still shown to visitors and known as the Camerina di Parisina. The episode later inspired Byron’s poem “Parisina” and Donizetti’s opera of the same name.
Este rule ended abruptly in 1598. Alfonso II d’Este died without a legitimate heir, and Pope Clement VIII refused to recognise his illegitimate cousin Cesare d’Este as duke, since Ferrara was held as a papal fief. The Este withdrew to Modena, which they held independently of the Church, and Ferrara passed under direct papal administration until the Napoleonic conquest in 1796. The city’s Renaissance fabric, including the castle and the Addizione Erculea, was inscribed on the UNESCO World Heritage List in 1995 under reference 733.
What you see
The Castello Estense still stands moated at the centre of the city, its fortress plan overlaid with the Renaissance additions commissioned by Ercole I and Alfonso I d’Este. Inside, the private Este rooms include the Sala dell’Aurora, with ceiling frescoes by Camillo Filippi from 1561, and the Camerina di Parisina, the dungeon associated with the 1425 executions.
Nearby, the Cathedral of San Giorgio presents a Romanesque-Gothic façade built between 1135 and 1175, with a triple loggia carved in a tradition linked to the same workshop responsible for the reliefs of Modena Cathedral. The Palazzo dei Diamanti, built for Sigismondo d’Este between 1493 and 1503, is faced with thousands of diamond-pointed stone blocks; the two street façades have their diamonds cut at different orientations, and the corner blocks are rotated so the pattern spirals around the edge of the building, a demanding piece of stonework for its time. The building’s authorship is not fully settled: a surviving 1492 building permit names Sigismondo d’Este as patron but no architect, and the attribution to Biagio Rossetti rests on comparison with his other documented work. Inside, the Pinacoteca Nazionale holds paintings by Cosimo Tura, Francesco del Cossa and Ercole de’ Roberti, the painters who defined the Ferrarese school of the fifteenth century.
Running north from the castle, the Corso Ercole I d’Este is the principal axis of the Addizione Erculea, one of the widest streets built in any Italian city before the nineteenth century, ending at the Porta degli Angeli, the Renaissance gateway of 1494 carrying Este heraldic emblems. In the older, medieval part of town, the Via delle Volte preserves a stretch of covered street where barrel-vaulted bridges link merchant houses across the road.
Practical information
- Castello Estense: the private Este rooms, including the Sala dell’Aurora and the Camerina di Parisina, are seen on a guided tour; check the castle’s own channels for current access and charges
- Palazzo dei Diamanti: the exterior can be viewed freely from the street; the Pinacoteca Nazionale and temporary exhibitions inside have their own admission arrangements, best confirmed directly with the museum
- Getting around: the historic centre is compact and largely level, and cycling is the customary way locals move through it
Getting there
Ferrara’s historic centre is small enough to cross on foot, and the city has an unusually high rate of everyday cycling with dedicated lanes running through the old town. For train, coach or road connections into Ferrara, current timetables and routes are best checked directly with the relevant transport operators.
