Situated
twelve kilometres from the sea, in the final stretch of the Ombrone valley,
Grosseto is the chief town of that marshy and harsh Maremma, for centuries reminiscent
of poverty, malaria and abandonment. The city followed the fate of this land
over the centuries, starting with its foundation, which took place in 1138,
when Innocent III transferred here the Episcopal see of nearby Roselle, which
by that time had declined.
In the 14th century, despite the serious environmental and economic decay, the
Grosseto area was the target of Siena's expansionist policies and was conquered
in 1337. The advent of the power of the Medici in 1559 led to the first works
to reclaim the territory and the definitive fortification of the city, but it
was only under the Lorraines, in the 18th and 19th century, that the reclamation
was carried out effectively and on a large scale, only being fully completed
in the first decades of the 20th century.
The altogether modern aspect of Grosseto, owed in part to the terrible damage
it suffered in the last world war, preserves an interesting old centre within
the beautiful 16th-century Medici walls.
