Torre Spagnola di Portoscuso
The Spanish tower of Portoscuso, an important example of coast tower, rises on a rocky buttress 30m a.s.l. It is part of a coastal defence system set by the Spanish during the second half of the 16th century against barbaric raids. It was built of local lava and volcanic tufa in 1577 or 1639; the structure, in the shape of a truncated cone, has one floor. Impressive is the dome vault for the presence of stiffening ribs without central pilaster; outside, the tower is characterised by decorative corbels. From the terrace you enjoy a charming view of the city and the Sulcis archipelago.
