Porto Flavia
Located in Masua, within the municipality of Iglesias, Porto Flavia is more than just a mining structure; it is a masterpiece of industrial engineering that seamlessly blends functionality with breathtaking landscapes. This innovative port system revolutionized mineral transportation by significantly reducing loading costs and time.
The complex features a 600-meter-long tunnel carved into the rock, culminating in an opening perched on a terrace overlooking the sea. This ingenious system allowed minerals extracted from nearby mines to be directly loaded onto ships, utilizing gigantic silos capable of storing up to 10,000 tons of material. The structure comprises two superimposed galleries: the upper one for storage and the lower one leading directly to the ship-loading area.
Visiting Porto Flavia is not just a journey into Sardinia’s industrial past; it is a visual and emotional experience. The terrace offers a stunning view of Pan di Zucchero, the tallest sea stack in the Mediterranean, rising majestically from the crystalline waters.

Grotta di Santa Barbara
Hidden within the heart of the San Giovanni Miniera, near Iglesias, the Grotta di Santa Barbara is one of the most extraordinary wonders of Sardinia and the world. Discovered in 1952 by miners during excavation work, this grotto is a unique geological treasure formed millions of years ago.
The journey to the grotto is an adventure in itself. Visitors board an electric train that travels through a mining tunnel, leading to an elevator that descends 36 meters into the mountain’s core. From there, a spiral staircase provides access to a vast chamber over 25 meters high, adorned with breathtaking columns of stalactites and stalagmites resembling crystal sculptures crafted by nature.
The walls and ceilings of the grotto are decorated with rare formations, such as honeycomb concretions, a phenomenon found exclusively in this location across Europe. A small underground lake, enveloped in silence, adds to the enchantment, reflecting light and creating mesmerizing color plays on the rocky surfaces.
One of the grotto’s most captivating features is the presence of dark brown tabular barite crystals, which make it a unique geological marvel. For nature and speleology enthusiasts, the Grotta di Santa Barbara offers a once-in-a-lifetime opportunity to witness the hidden wonders of the earth’s depths. Visiting this grotto is not only a visual experience but a journey into the depths of time, where natural and human histories intertwine seamlessly. The Grotta di Santa Barbara is an unmissable destination for anyone seeking to uncover the most secretive and fascinating aspects of the Sulcis Iglesiente region.
