Overlooking the Tuscan sea, Piombino hosts within its walls two important museums, designed by Leonardo da Vinci.

More than 2,000 exhibits, in the Archaeological Museum of the Territory of Populonia, testify to the transformation of the landscape and its society, from the Prehistoric era to the late antiquity age: inside there are warriors helmets, precious funerary objects with jewels and painted ceramics, vases and banquet bowls, portable amphoras, a mosaic with fish and a shipwreck, artefacts from ancient ruins and a little treasure trove of coins from the sea. A museum where you can't get bored: display cases, full-scale exhibitions of the activities and the ancient habitat, videos of archaeological discoveries and a large landscape reconstruction give voice and life to the precious relics kept within the halls. Not to be missed is the amphora of Baratti, a silver masterpiece from the sea which is the symbol of the Museum and the beauty of the land.
A new "multi-sensory" trail, and the introduction of three tactile-visual-auditory stations, that allow everyone to understand and enjoy the three symbols of the ancient history of Populonia, enrich a visit to the Museum: The Tomb of the Carri (the best preserved Etruscan tomb in Baratti and Populonia archaeological Park), the Roman mosaic named "of the Fish", and the silver amphora of Baratti are masterpieces of the Late Antiquity age. A new, simple and appealing way to "bring the story to life", even for the youngest and for those with no archaeological knowledge.

The story continues in the “Museum of the Castle and of the Medieval ceramics”, an impressive historic monument admirably restored in recent years. A technological and interactive exhibit tells of the archaeological finds that concerned medieval Piombino. Following the many transformations of the castle layout, you can retrace the story of the thriving and lively port facility of Piombino, through exceptional ceramic discoveries, that can be seen and touched, from the Middle Ages to  modern times.

The visit continues in the historic centre of Campiglia Marittima, inside the Museums of the Rocca, opened in 2008 after a detailed and honourable renovation. These museums represent an important historical connection between the village of Campiglia and the Archaeological Mine Park of San Silvestro, where the namesake medieval fortress stands.
The area includes the building of the “cassero” (the highest part of a castle) (where the archaeological finds unearthed during excavations of the fortress, have been placed), the ancient cistern (tank), the imposing embattled wall with the mullioned noble building (century XI - XV) and the aqueduct from the 1930s. The site also includes urban park usable area.
