The pentagonal tower in the south-east corner of the Castle houses the dungeons on its lower levels, where an ancient sleeping pallet with wooden boards and hundreds of curious inscriptions left by the prisoners are preserved. There has been a “dovecote” at the top of the tower since the seventeenth century.
The second and third floors house the town vinegar cellar, formed of three sets of barrels of traditional balsamic vinegar and complete with educational panels and the original furnishing.
