Province of Oristano, Sardinia, Italy
Bosa is a city and comune in the province of Oristano (until May 2005 it was in the province of Nuoro), part of the Sardinia region of Italy. Bosa is located about two thirds of the west coast of Sardinia, on a small hill, about 3 kilometers (2 miles) inland on the north bank of the Temo river. The city has maintained a population of around 8,000 people for a significant period of time, but has an urban character that has differentiated it from other places in Sardinia. Agriculture and fishing play an important role in the economy of the city, thanks to the river valley near the coast, surrounded by hills and plateaus.
The area was inhabited since prehistoric times, as evidenced by the presence of numerous domus de janas and nuraghe. It was probably founded by the Phoenicians, although little is known about the original settlement. Under the Romans it was a municipium. The current city of Bosa was founded in 1112 by the Malaspina, 2½ km (1½ miles) from the site of the ancient city (Bosa or Calmedia) In the early Middle Ages, as part of the Giudicato of Logudoro, it was a provincial capital . After the construction of the Malaspina Castle, the population gradually moved from the sea to the hills.
It remained in the hands of the Malaspina family until the 14th century when it was taken over by the Casa d'Aragona. Together with the rest of Sardinia, it was subsequently ruled by Spain through royal marriage. For a short time in the middle it was part of the independent Kingdom of Arborea (Giudicato di Arborea).
