Colle Val d'Elsa, located on the border between the territories of Siena and Florence, was once a place of political conflict. Home to many battles and sieges, it was also a melting pot of Sienese and Florentine artistic traditions.

The San Pietro Museum, after almost twenty years of closure, has reopened its doors to the public. Housed in the monumental complex of the homonymous monastery, it is the result of the fusion of the Civic and Diocesan Museum of Sacred Art with the Collection of the San Pietro Conservatory, the Bilenchi Collection and the Walter Fusi Collection.

The exhibition and the audio guide trace the history of the city through the artistic expressions of Colle Val d'Elsa, from the 6th century to the present day, with particular regard to the second half of the 16th century, when it became a seat to the bishop.

Particular importance is placed on the section dedicated to the Collection of Romano Bilenchi, which offers a rich library donated to the Municipality of Colle Val D'Elsa. The works of Ottone Rosai, Moses Levy and Mino Maccari tell about the formation of Romano Bilenchi and allow a more exhaustive delineation of the personality of the author.
