The museum is housed in the Palazzo Nuovo in the historic center of Piombino, made buit at the beginning of 19th century by Felice and Elisa Baciocchi (Napoleon’s sister) inside the fortified city.
Connected to the archaeological park of Baratti and Populonia, the museum is the main exhibition center of the Val di Cornia Parks and illustrates the history of Populonia from prehistory to the modern age, passing through the Etruscan period.
The archeological materials in the museum were found in the area between the 19th and 20th centuries. They were purchased by the state from private collections, through confiscations and donations. The most important group were held at the Florence Archeological Museum then moved to the current Museum for its first exhibition in spring 2001.
Here you can admire the famous Mosaic of the fishes, with its marine scenes, coming from the "Logge" of Populonia. Among the numerous works displayed, there's the silver amphora from Baratti, one of the most refined examples of late Roman artwork and an exceptional silver coin chest found in the Rimigliano seaside (San Vincenzo) in 2002, and now it is the symbol of the museum.
