What is the history of Castelsardo and where does its name come from?
Castelsardo was founded in 1102, when the Genoese family of Doria decided to build a defensive stronghold right on top of a promontory overlooking the gulf of Asinara. Its strategic location made it perfect for controlling the territory and the surrounding sea. Initially, the village was called "Castel Genovese". Only in 1769, after coming under Sardinian-Piedmontese rule, did it take on its current name: Castelsardo.
This long history has left traces everywhere: in the fortified walls, in the powerful fortress that houses the castle of the Doria, in the churches, and in the stone alleys. Walking around Castelsardo is like taking a journey through time, with overlapping eras living harmoniously together. The medieval structure has remained almost untouched, making this town one of the few in all of Sardinia that still retains its original layout.

One of the iconic places is undoubtedly the castle of the Doria, built in the 13th century and today home to the Museum of Mediterranean Weaving, which showcases baskets and traditional crafts made by skilled local artisans. From the castle, you also enjoy a spectacular view of the entire coastline and the blue sea.
The Catedral of Sant’Antonio Abate, located near the promontory, is another masterpiece worth visiting. Built between the 15th and 16th centuries, it houses remarkable works of art and notable frescoes. Don’t miss the crypt, carved into the rock, which hosts the diocesan museum. Other noteworthy churches include the one of Santa Maria delle Grazie, famous for hosting the rituals of Holy Week, deeply rooted in local tradition.

Why is the castle of the Doria so important?
The castle of the Doria represents the historical and symbolic heart of Castelsardo. Erected as a defensive fortress in the 12th century, it has preserved its structure intact to this day. The stronghold dominates the entire promontory, serving as an ancient sentinel against incursions by sea.
Today, the castle houses the aforementioned Museum of Mediterranean Weaving, a tribute to the local craftsman and women’s wisdom in creating perfect functional weavings. This museum is unique in its kind throughout Sardinia, and celebrates one of the most authentic forms of art of the island. The interior of the fortress hosts also temporary exhibitions and exhibition spaces dedicated to Sardinian culture and tradition.

The panoramic position makes Castelsardo a true natural balcony overlooking the blue. Walking through its alleys, you come across sudden romantic glimpses, where the contrast between ancient stone and the sea seems to tell stories from other times.

It’s an ancient nuraghe, a testament to the prehistoric Sardinian civilization.
If you love the sea, you can relax on the beach below the town, or head towards the crystal-clear sea of the nearby coves. The sunsets are spectacular and offer perfect backdrops for romantic moments or postcard shots.

Walking through its streets is an experience that takes you back in time. The stone alleys, the ancient pavement, and the absence of intrusive modernity make it all appear suspended between distant eras. It’s easy to be swept away by the allure and authenticity of the place.
What is the role of local craftsmanship?
The craftsman plays a central role in the life of the village. The weaving of baskets from straw and dwarf palm is one of the most characteristic expressions of Castelsardo’s culture. Women have passed down this knowledge for generations, creating beautiful and functional items.
