Porto Flavia is a remarkable feat of early twentieth-century industrial engineering, carved directly into the limestone cliffs of Masua on the southwestern coast of Sardinia. Commissioned by the Belgian mining corporation Vieille Montagne and designed by Venetian engineer Cesare Vecelli, construction took place between 1923 and 1924. Vecelli named the structure after his eldest daughter, Flavia.
The complex consists of two overlapping tunnels stretching approximately 600 metres into the mountainside. The upper gallery once carried a narrow-gauge electric Decauville train loaded with extracted zinc and lead ore. The lower gallery held a retractable conveyor belt system that could extend out over the sea to drop raw material directly into the holds of waiting cargo ships — eliminating the need for a deep-water port entirely.
Nine enormous vertical storage silos, capable of holding up to 10,000 tonnes of mineral ore, line the cliff interior. The ornamental concrete arches and observation tower at the seaward exit were an unusual design request from the mine's corporate owners, giving this working industrial site a surprising architectural elegance. The mine remained operational until the 1960s and is now a protected heritage monument open to guided tours.

My name is Alessandro Melis. I am a lifelong resident of Iglesias, the medieval town that lies just inland from the rugged Sulcis coast. My grandfather worked in the lead and zinc mines of Masua during the middle of the twentieth century, and the history of these cliffs is part of my family stories. I created this portal to help visitors plan their trip to our coast and understand the significance of this industrial monument.
Porto Flavia is not a simple cave. It is an engineering achievement of 1924, designed to resolve a difficult mineral transport problem. The structure is carved directly into the limestone, hanging over the sea. I hope you find all teh practical details on this website helpful as you prepare for your journey to this unique location. Feel free to explore the guides, check the local bus timetables, and discover the best spots to stay whilst you visit our region.
