The history of the Maremma goes far back into time, all the way to prehistory. From the seventh century B.C., with the presence of Etruscan civilization, it had become an important economic centre for the Mediterranean basin. The interesting archaeological sites in the Grosseto province make the perfect itinerary for following the traces of this people.
Grosseto is almost circular in shape and is surrounded by fortifications, constructed by Francis I. (1574-1587) and Ferdinand I. (1587-1609), which form a hexagonal enceinte with projecting bastions, with two gates only. The small cathedral, begun in 1294, is built of red and white marble alternating, in the Italian Gothic style; it was restored in 1855. The citadel was built in 1311 by the Sienese. Grosseto is on the main line from Pisa to Rome, and is also the starting-point (Montepescali, 8 m. to the N., is the exact point of divergence) of a branch line to Asciano and Siena.
