Oristano

Oristano is the youngest and smallest province in Sardinia, and was founded in the 11th century BC by the people of Tharros, a Punic city, the ruins of which can still be found nearby. In its early days Oristano was also the capital of the giudicato ("judiciary", equivalent to a Duchy or Kingdom) of Arborea.

The giudicato of Arborea was the last Sardinian kingdom to be conquered by the Catalan troops of the Kingdom of Aragon, with the 1478 defeat at Macomer.
