Housed in the rooms of the ground floor of Palazzo Corsini, the archaeological section is ordered according to educational criteria and illustrates aspects of the population and history of the settlements of the territory of Fucecchio and the adjacent areas through data materials dated between the Early Paleolithic and the 18th century, collected during archaeological research and excavations.

After an introduction on the appearance of the territory and the plioctic and villafranco sea and continental fauns, the Paleolithic and Mesolithic finds from the Cerbaians are on display. The presence of the first stable dwellers of Neolithic farmers and breeders and the metal ages are then documented by ceramics, lithic industries and metals, among which the materials of the Bronze Age are of particular interest (around 1500 BC .) from Stabbia. The large chronological arc corresponding to the Etruscan and Roman Ages are unfortunately the least documented. In the Imperial Age, in addition to the traces of centuriation  and rural settlements, some epigraphic data concentrated at Ponte a Cappiano indicate the existence of a more substantial population center, including the funeral epigraph of Tiberius Iulius Ianuarius and a marble votive area.

Two rooms are dedicated to the territorial lordship of the Cadolingi counts, to the foundation of the castle of Salamarzana, to the extinction of the family and to the birth of the castle of Fucecchio.

The narration, in addition to original finds, is entrusted to highly effective reconstructive images and videos that illustrate the various aspects of this process. Thanks to 3D scanning and printing techniques, the epigraphs of the Cadolingi are collected for the first time from all over Tuscany, while the virtual reconstruction techniques of the ancient landscape allow you to observe the transformations of the landscape, from the Salamarzana to the municipal Fucecchio, the same one that Leonardo depicted at the beginning of the sixteenth century.

The next room is dedicated to the production of ceramics which, between 1500 and 1800, was one of the most important economic activities in Fucecchio, completely disappeared and rebuilt through archaeological finds and archival documentation.

The last room illustrates an archaeological history of the Arno, from the Etruscan age to the Middle Ages. The role of the Valdarno trade route is illustrated by the examples of transport amphorae, of various origins and contents, witnessed along the river that allow you to follow the evolution of trade relations between the Arno and the Mediterranean for over a millennium. There are also exhibited the objects on board the Empoli wreck, which illustrates the mercantile activity along the river in the Middle Ages, and the large oak mill gear with the plastic and virtual reconstruction of the functioning of the mechanism.
