Bosa, Sardinia: What to See in the Colourful Medieval Town

Under that heavy April sky, Bosa felt even more dramatic. It is one of Sardinia’s most picturesque towns, a colourful riverside village where medieval history, scenic viewpoints and the relaxed seaside atmosphere of Bosa Marina come together in a uniquely captivating way.
The riverside promenade is one of Bosa’s most poetic spots. Walk along the Temo River, cross the historic Ponte Vecchio, and enjoy the colourful reflections of the town’s houses in the water.

Bosa is known for coral jewellery, asphodel baskets, traditional filet lacework, and its celebrated Malvasia di Bosa wine. Small artisan shops keep these traditions alive, their workbenches filled with coral beads, fine threads and woven fibres that reflect centuries of local craftsmanship. Wandering through the old town, you often glimpse artisans at work, preserving skills passed down through generations and giving Bosa a quiet, authentic charm that goes far beyond its colourful façades.

We visited Serravalle Castle, climbing slowly through the narrow lanes of Sa Costa until the town opened beneath us. The pastel houses seemed to glow against the grey, and the ascent had that quiet, suspended feeling you only get before a storm.

​At the top, the view opened like a storybook: the river winding below, rooftops stacked in warm colours, and the sea just visible in the distance — a panorama that stays with you long after you’ve left.
The fortress, built by the Malaspina family between the twelfth and thirteenth centuries, still watches over Bosa with a quiet, weathered dignity. Its stone walls, roughened by centuries of wind and salt air, felt even more imposing under that brooding April sky.

Inside the fortress you’ll find the church of Nostra Signora de Sos Regnos Altos, home to remarkable 14th‑century frescoes. We also climed the tower of the castle.

A good time to visit Bosa is around carnival. Bosa’s carnival is one of Sardinia’s most distinctive, a celebration that blends theatre, tradition and a touch of mystery. The ritual reaches its peak on Shrove Tuesday (Martedì Grasso) during the final daytime hours of the Bosa Carnival. The procession of S’Attitidu, with its black‑masked mourners carrying a symbolic doll, is both dramatic and deeply rooted in local culture. It’s an event that transforms the town: the narrow streets fill with music, ritual and colour, offering a glimpse into Sardinia’s most ancient customs.
