One of the most important pieces in the collection is the barrier corselet which probably belonged to Carlo Emanuele I of Savoy, or to one of his sons. It is one of the most important armorer's works that came out of a Milanese workshop at the end of the sixteenth century and bears the mark of the Master of the Castello a Tre Torri, an armorer who remained anonymous, but who has marked a large number of luxury armor that still today they stand out for perfection and refinement. Together with Pompeo della Cesa, the Master of the Castle introduced a new lexicon in the forging and decoration of armor in the years between the sixteenth and seventeenth centuries, and the Brescia corselet is a testament to this: forged with thick and robust plates, but with an almost perfect articulation of the limbs. The barrier corsets are among the most resistant, since the type of tournament was particularly bloody: two teams of knights faced each other on foot, with all types of weapons, but separated by a barrier, and therefore it was not necessary to protect the legs. Victory went to those who managed to knock out all opponents.
