Portoscuso is a seaside village of about 4,800 people on Sardinia's south-west coast, facing San Pietro island. Its name probably comes from the Catalan Puerto Escús, "hidden port", and its history has been tied to tuna fishing for centuries. The compact old town around the Spanish tower, small beaches and seafood cooking make it a pleasant stop for couples and families, and a handy departure point for ferries to Carloforte.
What to see in Portoscuso
The Spanish Tower
The village's symbol, this 16th-century coastal tower watches over the little harbour from a rocky headland. Built to spot Barbary pirate ships, it is now the best viewpoint over the sea and San Pietro island, especially at sunset.
Su Pranu tuna fishery
Active since the mid-16th century, the tonnara is one of the most important in the Mediterranean. Bought by the town in 2006 and partly restored, it holds the buildings where tuna was processed and the little church of Sant'Antonio da Padova, considered the oldest in the village. Walking through it reveals how deeply Portoscuso is bound to the sea.
The old town and Santa Maria d'Itria
The lanes of the centre, lined with low fishermen's houses, climb to the church of Santa Maria d'Itria, built around 1655 and rebuilt in 1956. The seafront makes a pleasant stroll to the harbour.
Punta Niedda and Capo Altano
North of the village the coast rises into the Crobetana cliffs, over a hundred metres high, up to Capo Altano, with 1930s fortifications and a wide view over San Pietro and the open sea.

History
The area was inhabited from the Neolithic, as rock-cut tombs, megalithic circles, nuraghi and Phoenician, Punic and Roman cemeteries show. In the Middle Ages it belonged to the Judicate of Cagliari and then to the counts of Donoratico. The modern village grew up in the 16th century around the tuna fishery, with fishermen from Sardinia, Sicily and Ponza and coral fishers from Marseille and Majorca. In the 17th century it suffered pirate raids, including an attack on the fishery in 1660. It became an independent municipality in 1853. After the war the Portovesme industrial zone changed the economy and boosted the population, but the old town and the tonnara remain the village's heart.
Food and local products
Bluefin tuna rules the table here, in every cut: belly, tuna roe bottarga, musciame (dried fillet) and pasta sauces. There is also fresh fish, lobster and shellfish. Pair it with Carignano del Sulcis or a white Vermentino. To take home: preserved tuna, bottarga and a bottle of Carignano.
Festivals and traditions
The main feast is Santa Maria d'Itria, on the Tuesday after Pentecost, with a procession and events in the square. June brings St Anthony of Padua around mid-month and St John the Baptist, with traditional eve rites. The tuna season, from spring to early summer, remains a defining moment for the whole community.
