Bosa

Bosa stands on the northern bank of the Temo, a short distance inland from Sardinia's western coast. The ancient settlement was a Roman municipality, while the later town grew on the hillside beneath the castle of the Malaspina. People gradually moved inland from the coast as the fortified centre developed.

The present town was founded by the Malaspina in the thirteenth century, inland from the older site. Bosa belonged to the Judicate of Logudoro before coming under the Malaspina family. In the fourteenth century the Crown of Aragon took the town; for a time it also formed part of the Judicate of Arborea during the struggle for control of the island. The castle above the river remained a reminder of the lords who had established the medieval town.
