The Museum, reopened in 2004, is situated in historic Palazzo Corsini. Along with sections dedicated to art collections, an archaeological section documenting some aspects of the history of settlements in this area has been set up. Particularly interesting, as regards the natural sciences, is the Lensi Ornithological Collection, formed in the late 19th century and the early 20th by the physician Adolfo Lensi. The collection was conserved by the Lensi family until 1978, the year in which it was acquired by the Communal Administration of Fucecchio, which moved it to the Town Hall. Now occupying the top floor of Palazzo Corsini, it is dedicated mainly to the fauna of the Padule di Fucecchio, and is made up of around 300 specimens. Some of the specimens were stuffed by Lensi himself, while others were prepared by other taxidermists.
