The Pinacoteca Comunale di Castiglion Fiorentino is housed in the ancient, restored church of Sant’Angelo, inside the defensive enclosure of the Cassero. The church has medieval foundations from the eleventh century, but in the sixteenth century it was turned into a convent and its original apse was replaced by a “nun’s choir.” Its collections mainly comprise works of sacred art, including major paintings of the Tuscan school from the thirteenth to seventeenth centuries, and rare examples of medieval goldwork. All the works are from churches and monasteries in Castiglion Fiorentino and environs. The first part of the book is a guide to the museum itself, with photographs, descriptions of the works, and background information. The second part takes the reader on a route through the historical center of Castiglion Fiorentino and the Val di Chiana Aretina region.
