Castello Estense
The Castello Estense or castello di San Michele is a moated medieval castle in the center of Ferrara, northern Italy. It consists of a large block with four corner towers.
History
On 3 May 1385, the Ferrarese people, driven to desperation by taxes and flooding that had brought ruin upon them, took themselves to the Marquis Niccolò II d'Este's palace to ask the advice of Tommaso da Tortona, the high official held to be responsible for this grave situation. Nicolò tried to calm the revolt all day, but by the evening it was clear that the people's spirits were getting more and more angry and that the very safety of the Estensi was endangered. The order was therefore given to summon the disgraced Tommaso, who was given confession and communion and then given to the crowd, who literally tore him to pieces.Image:Castello ferrara pontelevatoio.jpg|thumb|left|upright|The western drawbridge. The tower features machicolations near the top.
This episode, which resulted later in the death of the leaders of the revolt, convinced the Marquis that the family's palace was insufficient to guarantee the security of the nobility in the event of riots. He therefore ordered the construction of a defensive fortress on the north side of the Palazzo, entrusting the project to the architect Bartolino da Novara. He used a pre-existing tower, which was part of the defensive walls, at that period very much to the south of the present ones, running, roughly speaking, along the line of the present Corso Giovecca and Viale Cavour. The tower was joined by curtain walls to another three newly built for this project. Between the Este residence and the new fortress was built an aerial passageway to allow people to flee from one to the other.
As the city grew the city walls were moved, so the defensive function of the castle became less important and apartments began to be built in its interior, which was by now considered an annex to the court palace. From the time of Ercole I d'Este on, there are many records of construction of apartments, and of their enlargement and enhancement. The definitive transformation works were ordered by Ercole II after a fire in 1544, which had damaged the previous accommodation. The architect Girolamo da Carpi gave the castle the external appearance which can be still seen today, although the interior has been remodelled several times across the ages. After the departure of the Este to Modena, the castle became the residence of the Papal Legate who administered the Ferrarese territory as civil governor. There were few changes made to the structure of the building, the most obvious being the increase in height of the north ravelin.
In 1860 Ferrara was annexed to the Kingdom of Italy. The castle, now state-owned, was bought for 70,000 liras in 1874 by the Province of Ferrara that utilized the structure as headquarters of the Prefecture. In the subsequent decades, the castle underwent many small restoration projects, especially between 1910 and 1930, when some very questionable attempts were done. During World War II it was severely damaged by Allied aerial bombing, thus it was partially reconstructed in 1946.
In 2002, at the initiative of the Provincial administration, the "Castle for the City" project was started: it involved a massive, €2.7m restoration of the castle and a series of exhibition of international significance, such as: "The Triumph of Bacchus: Masterpieces From the Ferrara School at Dresden", inaugurated in 2002 by the then President of the Republic Carlo Azeglio Ciampi, and "A singular Renaissance: the court of Este in Ferrara", inaugurated in 2003 at the Centre for Fine Arts of Brussels and later in Ferrara at the presence of the then President of the European Commission Romano Prodi. In 2004 the whole project of restoration was completed with two significant events: the inauguration of the €1.7m new museum display ideated by archistar Gae Aulenti and the restoration and temporary opening to visitors of the Camerini d'Alabastro, secret rooms built by Alfonso d'Este.
Following the 2012 Northern Italy earthquakes, one of the towers partially collapsed and underwent restoration works.
Exterior
On the outside, the castle essentially presents the appearance given to it by Girolamo da Carpi in the second half of the 16th century. Surrounded by a moat, it has three entrances with drawbridges fronted by brickwork ravelins. The fourth entrance, to the east, was removed to make room for the kitchens.At the bottom, the appearance of the building still recalls a mediaeval fortress, but higher up, da Carpi replaced the battlements with elegant balconies in white stone, making it higher again by constructing a higher storey, covered by a skew roof. The towers were improved and made more graceful with roof terraces.
The courtyard, nowadays fairly austere, was frescoed. In particular, at the top were portraits of all the ancestors of the Este family: the only ones surviving, considerably damaged but still discernible, have been detached and placed under the portico on the east side of the courtyard.
The wells were to provide water in time of drought; the round stone balls that are seen about the place are ammunition for catapults.
