The castle, belonging to the Sanseverino family, takes its name from the conspiracy organized inside by the barons of the kingdom, against Ferdinand I of Aragon, king of Naples. The conspiracy took place on October 1, 1481 and ended with the bloody massacre of the barons in the great hall on the second floor; from that moment on, the castle was called "Malconsiglio".
The castle has the shape of a parallelogram, flanked by seven towers, the oldest of which are square, two bitorri and some circular towers, placed at the top of the building. It is built on two levels, with a gallery that dates back to a restructuring commissioned by the Revertera family in 1600. The most beautiful part of the castle is the Hall of the Star or of the Spirits, in whose niches carved into the walls were kept the treasures of its inhabitants.
