Bosa: Malaspina Castle, Casa Deriu
and the city of colours on the Temo River

“Bosa's houses are painted pink, orange and ochre yellow, and they run all the way down to the Temo. From the medieval castle above, it looks like a nativity scene — but one where people really live.”

In Bosa, about 45 km from Alghero along the scenic coast road, in one day you can see Malaspina Castle (Castello Malaspina, 1112) with the frescoed Church of Nostra Signora de sos Regnos Altos, the colourful Sa Costa quarter, the Temo riverside and the Casa Deriu house museum. Bosa is one of “I Borghi più belli d'Italia” (Italy's most beautiful villages) — and for once the title isn't an exaggeration. Castle and church: a few euros to get in. Sunset over the Temo: free.


In summer the castle fills up from the afternoon — come in the morning for the finest view and the best light for photos.

Malaspina Castle and the frescoed church

Malaspina Castle (also called Serravalle Castle) dominates Bosa from the top of the hill: it was built in 1112 by the Tuscan marquises Malaspina dello Spino Secco. Inside the castle stands the small Church of Nostra Signora de sos Regnos Altos, which preserves Catalan-Sardinian frescoes from the 14th–15th centuries, a rare cycle for the island — a treasure hidden inside a medieval fortress.

Bosa can be visited in a day from Alghero — but it deserves a night for the sunset over the Temo. → See where to stay near Bosa

Malaspina Castle (Castello Malaspina)

A 12th-century medieval fortress (1112) with panoramic views over Bosa and the Temo; admission charge. The Church of Nostra Signora de sos Regnos Altos inside preserves 14th–15th-century frescoes. Walk up from the centre (20 min) — worth every step.

Casa Deriu and the Pinacoteca Atza

A house museum in the old town, near the Temo: a furnished 19th-century upper-class apartment, temporary exhibitions on Bosa's traditions and, on the top floor, the collection devoted to the Bosa-born painter Melkiorre Melis. Opposite, the Pinacoteca Atza gallery shows the canvases of Antonio Atza. Small but well kept, right in the centre.

Sa Costa — the historic quarter

The medieval Sa Costa quarter is Bosa's picturesque heart — narrow lanes, colourful houses, flowers on the balconies. A fascinating maze to explore on foot, unhurried, losing yourself among the colours.

Riverside and river port

The Temo riverside is one of the most evocative in Sardinia — fishing boats, colourful houses reflected in the water, old bridges. Beautiful at any hour, sublime at sunset when the light sets the façades ablaze.

Boat trip on the Temo and Malvasia tasting
Bosa is famous for Malvasia di Bosa, a DOC wine produced in small quantities. Some tours combine a winery tasting with a boat trip on the Temo: a different way to experience the town.

FAQ — Bosa

Is Bosa really one of Italy's most beautiful villages?
Yes — Bosa is a member of the “I Borghi più belli d'Italia” club. The recognition is fully deserved: the medieval Malaspina Castle, the colourful Sa Costa quarter, the Temo riverside with its fishing boats and houses reflected in the water, and the beach at Bosa Marina 3 km away. Bosa is rarely as crowded as Alghero or Stintino — it keeps a genuine atmosphere all year round.
How far is Bosa from Alghero?
Bosa is just under 45 km from Alghero, about 50 minutes–1 hour along the scenic coast road (SP105), with sea views the whole way: it's one of the most beautiful coastal roads in Sardinia. From Sassari it's about 80 km and from Porto Torres about 85 km via Alghero: allow about 1h30.
