Masua and Porto Flavia

Porto Flavia is far more than a former mining facility. Built into the cliffs of the Iglesiente in south-west Sardinia, it was an innovative engineering solution designed between 1922 and 1924 to transform the way minerals were loaded onto ships, dramatically reducing handling time and costs.

An innovation in mining logistics

Porto Flavia was created to load ore extracted around Masua directly onto ships. Two superimposed tunnels and large storage silos allowed lead and zinc ore to be moved efficiently to a loading arm extending out over the sea.

The engineering behind the project

The complex was designed by mining engineer Cesare Vecelli, who named Porto Flavia after his daughter. The result remains one of Sardinia’s most original examples of industrial engineering and mining heritage.

A tunnel between cliff and sea

The Porto Flavia tunnel system extends for hundreds of metres through the cliff and opens to a spectacular view of Pan di Zucchero. Guided visits combine industrial history with one of the most dramatic coastal settings in Sardinia.

The mining village and museum

The Masua area also includes former mining buildings and community facilities that reflect the life of a once-thriving workforce. Museum displays and preserved machinery add further context to the technology and working conditions of the mining era.

Tickets and opening hours

Access to Porto Flavia is controlled for safety reasons and advance booking is strongly recommended. Guided visits follow the tunnel route and require closed shoes and practical clothing.

Visitor tips

Arrive before the scheduled entry time and follow the site’s current safety instructions. Rules for children, animals and accessibility can change, so check the official visitor information before booking.
