Roselle was one of the main Etruscan cities (V/VII century B.C.).
It controlled a large portion of the territory that spread to the borders of Volterra to North, with Sluices to East,
Vulci to South, until the rivals Vetulonia to the West.
The Etruscan city was set near to the great lake “Prile” that extended from this zone up to the modern town of Castiglione della Pescaia.
This lake was born from the sea receding graduates which happened in the previous centuries, which was named after the Etruscan God Aprilis,
that comes from etymologically, also from the month of the Roman calendar, April.
In the folowing centries Roselle saw a phase of decline coinsiding with the Roman conquist (III/IV century B.C.), which at the same time happened in all of Northern Etruria.
After the falling of the empire, different to Cosa ( modern Ansedonia), Roselle conserved a certain vitality so much that it was chosen as the seat of the bishop.
(V century A.D.) therefore as a principle centre of the evangelistic of Maremma, like the towns of Sovana and Populonia.
Very soon a decision made by the Pope followed the Lombard invasion (VI century A.D.) which inglobed Roselle also in the last diocese.
In the VII century the conquist of the Lombards was conclused, nevertheless the Carlovingian era Roselle continued to conserve its spiritual centre,
creating a permenant dispute with the Pope.
In the early years of the IX century the first documentation of the expansion of the Aldobrandesca family rose, that for the will of Franchi,
returned to take control again of the Tuscia empire and Maremma. In the X century Roselle became the administrative centre of Sir Aldobrandeschi’s family
who wanted to transform Roselle into a city that then became Grosseto, at that time it was a locality of little importance.
In 1138 the bishops seat and titled "civitas" passed to Grosseto, seeing the end of the central position of Roselle.
Around XIII century saw the expansion of Siena.
