Bosa Castello

Bosa is located within the “Planargia”, a region in the north-west of Sardinia. Not far from the sea it lies along Temo river. This is a unique feature of our Island. Dominating the town of Bosa we find the “Malaspina” castle which is surrounded by the old medieval village. The origin of Bosa is testified by a Phoenician inscription “Bs’n” of the 9th century B.C., the name of the garrison that rose at the Temo river mouth. The most resounding news about Bosa is dated from roman age when the town of “Bosa Vetus” rose near the present San Pietro church.

This roman town had never been abandoned despite continuous Arabic raids; as a matter of fact in 1062 was started the building of the Cathedral consecrated to San Pietro, always along Temo river, but more upstream. Temo river is the only navigable river in Sardinia. We can go upstream for about 5 km, as far as the old roman bridge ruins, not far from the old roman San Pietro Cathedral. Going upstream is an evocative experience thanks to its wild landscape along both banks. While the part of the river that divides Bosa allows us to admire the old bridge, the antique buildings and the old tanneries “Sas Conzas” used from 1700 to tan leather, this is one of the first examples of industrial archeology in Sardinia.

Non manca certo la possibilità di trascorrere qualche ora in spiaggia. Le coste bosane offrono numerose insenature con spiagge e roccia che garantiscono, nonostante il massiccio afflusso di turisti, ampi spazi di tranquillità per tutti.


Of course, in Bosa we can spend a couple of hours lying on the beach. Bosa has a large coast with several inlets separated by high rocks which let everyone have a quiet place even though there are lots of tourists.


In 1112 the marquis of Malaspina built a castle on top of “Serravalle” hill. Since then the inhabitants started moving from the low part of Bosa, near the river and less defensible from Arabic raids, to the uphill area near the castle protected by high walls. The whole complex was built during different stages, starting from a couple of towers of the donjon to the surrounding walls. Later, around 1330, the surrounding walls were widened by building a couple of squared towers. A further broadening consisted of the building of a pentagonal tower and the octagonal embankment towards the sea, and in the extent of the surrounding walls all around the hill. In this way the complex had a perimeter of 300 metres spaced out with seven towers, containing a territory of more than one hectare.Bosa Fiume Temo


At the foot of the castle we have the late medieval village of “Sa Costa” which still has an historical fascination. The architecture of this village is adapted to the specific truncated cone shape of the hill, with flights of steps cutting a horizontal path in an asymmetric way. The long lines of terraced houses form like a crown, these lines are equidistant from the walls line of the castle.


The houses we find along these narrow paths are usually composed with one room for each floor; some of these rooms are excavated into the hill. Almost each house has two entrances in the staggered floors which let people enter from the downhill entrance and from the uphill entrance. The façades are decorated with red trachyte enriched with architraves carved in bas-relief belonged to the Hispanic-Aragon age.
