The Parco Tecnologico e Archeologico delle Colline Metallifere Grossetane (Metalliferous Hills of Grosseto Technological and Archeological Park) is the first national theme park established by the Italian Ministry of the Environment and Land Conservation. Its features stand witness to the mining and metallurgical activities performed in this area across the ages, from the time of the Etruscans to our era. The Park encompasses seven northern Municipalities of the province of Grosseto: Follonica, Gavorrano, Massa Marittima, Montieri, Monterotondo Marittimo, Roccastrada and Scarlino, each with its own distinctive features. Near Monterotondo Marittimo lie boric acid fumaroles that supply a geothermal power plant. In the area between Massa Carrara and Gavorrano lies the mysterious and crystal clear small lake named Lago dell’Accesa. The large municipality of Roccastrada features the stunning Castello di Montemassi, a place filled with history, and artistic connotations, most famously depicted in the “Guidoriccio da Fogliano at the siege of Montemassi” fresco painted by Simone Martini in the Sala del Mappamondo of the Palazzo Pubblico di Siena. A mandatory stop along the hills trail is Vetulonia, a medieval burg perched at 300 meters above sea level in the municipality of Castiglione della Pescaia. The burg was once an important Etruscan town, and now its vast archeological site and necropolis attract history lovers and curious visitors in-between guided tours and hiking trips. Those who have had their fill of history can also plunge into the crystalline coastal waters of Castiglione della Pescaia, a multiple award-winning premier tourist destination, famous for its pristine beaches, sea water quality, beach facilities and eco-friendly practices.
