Bosa
Bosa sits at the mouth of the Temo — Sardinia's only navigable river — where a row of ochre and terracotta houses lines the southern bank like a sentence that trails off into hills. The Malaspina castle watches from above, its seven towers still more or less intact after seven centuries. What makes the town specific is the river itself: walk upstream along it and you pass the stone tanks of the old tanneries, then arrive, after two kilometres, at a Romanesque church that was already old when the town was founded.
The medieval quarter, Sa Costa, climbs steeply toward the castle in a tangle of stone staircases and tall narrow houses. Down on the flat, the cobbled Corso Vittorio Emanuele is lined with 17th-century buildings that shade the street through the long afternoon.
💛 What travellers fall for
People who come back tend to mention the walk to San Pietro Extramuros — upstream along the Temo, past the tanneries, to the Romanesque church with its Gothic facade. Do it in the morning before the heat settles. The Sas Conzas museum deserves more time than most visitors give it; the original stone washing tanks on the ground floor are quietly extraordinary.

How Bosa came to be
The site has been inhabited since at least Phoenician times, and Bosa later functioned as a Roman municipium. The town you walk through today, however, was founded in the 13th century by the Malaspina, a Tuscan noble family who built Castello di Serravalle — some of its towers dating from 1112 — on the hill above the river. Bosa remained under Malaspina control until the 14th century, when it passed to the Crown of Aragon.
For centuries the river sustained a tanning industry: hides were processed in stone tanks along the southern bank, and the trade continued until after the Second World War. In 1807 a royal decree made Bosa the capital of its own province. The tannery buildings, declared a national monument in 1989, now house the Sas Conzas museum.

When to go
Summers are hot and dry, with temperatures regularly above 30°C — the river walk is best tackled early. Spring (April–May) and September bring warm, manageable days and far fewer visitors; winters are mild but some sites reduce their hours considerably.
