Castello Estense
You start at a real moated castle in the middle of the city: one big brick block with a tower at each of its four corners, water all around. It looks like it was built to keep enemies out, and it was, but the enemy the Este family feared most was their own people.
On 3 May 1385, the Ferrarese, crushed by taxes and ruined by floods, marched on the palace of Marquis Niccolò II d'Este to confront Tommaso da Tortona, the official they blamed. Niccolò tried all day to calm them. By evening the family itself seemed in danger, so Tommaso was given confession and communion and then handed to the crowd, who tore him to pieces. The revolt's leaders were later put to death, and Niccolò drew his own conclusion: the family palace, today's Palazzo Comunale, was not safe enough.
He had the architect Bartolino da Novara build a fortress on the palace's north side. Bartolino reused an existing tower of the old city wall, the Torre dei Leoni, and joined it with curtain walls to three new towers. An aerial walkway, perhaps of wood, linked palace and fortress so the family could flee from one to the other.
As Ferrara grew and its walls moved outwards, the castle lost its military role and filled with apartments. From Ercole I onward the rooms kept expanding, and after a fire in 1544 Ercole II ordered the final transformation into a residence. Going inside costs an entry fee and is worth it if you want to feel how the family lived.
From the castle it is 400 m, about 5 minutes, to the cathedral, the other pole of medieval Ferrara.
