Conceived as a military garrison, the building, in the first half of the 16th century, took on the appearance of a noble residence with a large garden, of which the furnishings, paintings, majolica, various busts from the Roman era and the entire archive are preserved of the Bufalini family. The vaults of the rooms host the paintings of Cristofano Gherardi, a Tuscan artist of mannerist training who, between 1542 and 1552, reproduced mythological fables and grotesque decorations in the main tower, in the Hall of the Gods and in the Room of Apollo. The Castle has hosted events (including the Living Nativity Scene), conferences (including the one on Francesca Turini Bufalini), fairs (such as Sapori e mestieri), book presentations , educational activities also in relation to school-work alternation.
