What is Bosa known for?

Thirteenth-century Tuscan fortress of the Malaspina di Spino Secco, called by the Aragonese the key to all Sardinia in the Sardinian-Catalan war. DOC sweet wine from the Planargia hills behind the town, in dry, semi-dry, natural sweet and sweet versions, one of Sardinia's classic dessert wines. Nineteenth-century tanneries lining the south bank of the Temo in identical industrial blocks, an intact piece of Sardinian industrial heritage.

When is the best time to visit Bosa?

May–Oct. May through October is the working season on the Temo: river boat trips, the castle climb, the colour-washed quarter, the Malvasia tastings in the Planargia. July and August push past thirty-two degrees and the centro storico empties between two and five each afternoon. April and the second half of October are dry and mild, the right window for the Sas Conzas walk and the cliffs of the Capo Marrargiu coast. November through March brings rain and short days, with the Carnival of Bosa, called Karrasegare Osinku, the strangest event of the year: men dressed in black mourning robes and the bizarre Giolzi street-game of January and February.

Bosa is a comune in the province of Oristano, Sardinia region of Italy, about 63 kilometers from Sassari.

Why come

Bosa sits three kilometres inland from the western coast of Sardinia, on the north bank of the Temo, the only navigable river on the island. The Castello di Serravalle, built around the second half of the thirteenth century by the Tuscan Malaspina family of Spino Secco, dominates the town from the hill above the centro storico. During the Sardinian-Catalan war the Aragonese described it as one of the noblest castles in the world and the key to the entire island.

Below the castle, the houses of the Sa Costa quarter step down the slope in lines of pink, yellow, blue and green to the river. On the opposite bank stretches Sas Conzas, the nineteenth-century tannery district, identical industrial buildings with stone soaking tanks where Bosa hides were processed for export. The Planargia hills behind the town produce Malvasia di Bosa DOC, one of Sardinia's classic sweet wines, alongside olive oil.
