Tonnara Su Pranu

Tonnara Su Pranu is a 16th-century tuna fishery turned cultural attraction in Portoscuso, where the colorful, narrow-streeted architecture still tells the story of the fishermen who once worked here. It's a surprisingly evocative place — part living history, part event venue, hosting things like the beloved Calici in Tonnara wine festival each summer. Wander around, soak in the marina views nearby, and get a real feel for what shaped this corner of Sulcis Iglesiente.
