The Rocchetta courtyard was the most protected part of the castle, and the dukes took refuge here when the castle was under attack. If you look up, opposite Bona Tower you'll see Castellana Tower: not by chance, the duchy's treasure was guarded here in the safest part of the castle, and was a treasure worthy of the "Lord of the Rings"! Don't miss the Renaissance decorations on the ceiling of the portico, with the mottos of the Visconti and Sforza families.
