It was built in1385by the Marquis Niccolò II D’Este following a dangerous revolt, to defend the lords against the populace. In the Middle Ages, in addition to the name “Estense,” which derives from the D’Este family, it was also given the nameCastello di San Michele(Castle of Saint Michael) because the first stone was laid on September 29th, the day dedicated to the Archangel.
The peculiarities
Surrounded by itsmoat, which is still fed by the Po di Volano, it has a capacity of about15,000 cubic meters of waterwith a depth between 3 and 5 meters, making itnavigableand an ideal habitat for Carp and Catfish.
The moat, along with thedrawbridges(which are still perfectly preserved), is a reminder of its origins as a militaryfortress, which in time became the residence of the ducal court, one of the most influential dynasties of the Italian Renaissance.
Alfonso d’Este, Lucrezia Borgia, Ercole d’Este, and Isabella D’Este are some of the illustrious figures who lived in the Castle.
After1598, theEste Castle(Castello Estense) passed to the Papal States and consequently became the residence of Cardinals linked to the Pope.
