Overview
The Malaspina Castle (otherwise known as the Castle of Serravalle) overlooks Bosa from the top of the Serravalle hill. It is a scenic complex built in various stages starting in the second decade of the 12th century, when the Malaspina family had some of the towers of the donjon built: the great tower was built in light pink trachyte, at the base the rustication is in red trachyte ashlars. The castle was later expanded to a perimeter of 300 metres, interspersed with seven polygonal and square towers. From 1468 onwards, terraces were built for the placement of firearms, from which an extraordinary panorama opens up over the roofs of the old town, the domes of the churches and the course of the Temo as far as the sea. Inside the castle, in the parade ground, the Church of Nostra Signora de sos Regnos Altos was erected in the 14th century (later remodelled), which preserves a splendid cycle of Italo-Provençal and Franciscan frescoes, dating between 1350 and 1370. The cycle is articulated on the three main walls of the primitive building and depicts the vanity of material goods and the redemption from death offered by the Eucharist.
