The story of the Lady of the Castle "friend of the people" is re-enacted every year by the people of Verrès, still grateful for her lovely gesture, which was most unusual for the time.

The year was 1450 and Caterina di Challant and her consort Pierre d'Introd came down to Verrès, escorted by a handful of armed guards. After lunch with the Reverendo Pietro di Chissé, Provost of the Minster of Saint Gilles, they made their way to the main square in front of the church. Everyone started dancing in time with the music, played on the fife and drum, and Caterina, leaving her consort's side, danced with the lively, young people of the town. The people's enthusiasm was at a peak and a unanimous cry went up: "Vive Introd et Madame de Challant".

The echo of that joyful cry can still be heard today. Over 500 hundred years have gone by but not erased the memory of that feast day, and so every year, the whole population of Verrès eagerly awaits the celebration of Carnival time, with great enthusiasm. Playing the part of the nobles is a much sought-after role by all the townsfolk. There is a rich programme of events, with parades in costume every year, followed by a beautiful ball in the halls of the Castle that overlooks the town.

The Carnival reaches its climax every year when the main characters enter the town square. At the end of this part of the event, the people listen intently to the town-crier, who declaims the "Proclamation of the Citizenry" in a "strange but comic" ancient language.
