The Museum, founded in 1969, was reopened in 2003 in the new Palazzo Corsini site overlooking the medieval town’s main square, Piazza Vittorio Veneto, facing the Collegiata church of San Giovanni Battista. Behind the Museo is the large public park, the city’s focal point and original core with the ruins of the early-medieval Salamarzana castle, which belonged to the Cadolingi Counts, and the 14^th-century Florentine fortress.

The palazzo dates to the 14^th century; under the ownership of Giovanni dei Medici, just after the middle of the 15^th century, the entire complex was transformed into a farm, which then passed to the ownership of the hospital of Altopascio, and in the 17^th century to the Corsini family, from whom the Municipality of Fucecchio acquired it in 1981 to be used as a cultural services site. The Museum is next to the Municipal Library, the Historical Archive and the Youth Center.
