Seventeen statues of grotesque dwarves rest on the walls sorrounding the Villa. Probably inspired by the drawings of Callot, made famous by the populars prints by the Remondini printers from Bassano del Grappa, they reproduce the classic characters of the Commedia dell'Arte. Giandomenico is believed to be the author of the preparatory drawings of the sculptures.
The legend of the dwarf princess is tied to these characters: confined by her parents among the high walls of the castle with twenty dwarf servants at her services, she takes off her life once she discovers her deformity.
