The Civic Archaeological Museum of Castiglion Fiorentino collects materials found since the late 1980s during archaeological campaigns carried out in the area. In this regard, of particular note are the discoveries made in the Piazzale del Cassero, referable to a sanctuary located in the ancient settlement of the town.
The exhibition is divided into five rooms located on the top floor of the Palazzo Pretorio and deals with various themes pertaining to the ancient Etruscan center and neighboring settlements. These, rich in archaeological evidence, held artifacts ranging from the Late Bronze Age to beyond the Late Antique period. Of notable importance are the reconstruction of the roof of the Etruscan sanctuary (late 5th-2nd century B.C.), the Brolio and Montecchio deposits, and the evidence found at the Etruscan site of Brolio Melmone, a center of production and trade.
Also on display since 2008 is a medieval section to complete the historical-archaeological narrative of Castiglion Fiorentino, including archaic and Renaissance majolica from the 9th century onward.
The museum features numerous multimedia supports, explanatory panels and a modern computer and educational facility.
The underground archaeological trail of the Cassero includes part of the areas investigated during the numerous excavation campaigns. The continuity of life on this archaeological site is the impressive aspect of this exhibition, beginning with testimonies of the first Etruscan settlement (8th century B.C.) through to the medieval age.
