Located 50 km southeast of Sassari, in the Logudoro region, a territory that in the Middle Ages, constituted the ancient Giudicato of Torres. The place name derives from the Latin "Bonus Orbis," meaning "good land."
In ancient times it seems to have been built in "Su Monte" (M. Cacau) and had the church of San Simeone as its parish. It is said that that lookout position was chosen by the people of the valleys surrounding the present town out of a need for security, because, from that point, where the Campeda plateau ends, the territory below could be controlled. They were seeking, in fact, a refuge so that they could defend themselves from the raids of the Moors who, after sacking the coast of Bosa, pushed inland into the Bonorva area. The abandonment of S. Simeone is supposed to have been brought about by the plague of 1376. The inhabitants then descended from the high plateau and settled on the slopes of Muristene, where the villa of Bonorva was refounded with the new parish of Santa Vittoria. The fantastic aspect of the abandonment is the legend of the "Maghedde Flies," sent by God as punishment for their sins. They stung and killed everyone they encountered, until a "righteous man" locked them in an amphora that he sealed and buried under the church of St. Simeon. The inhabitants offered the saint part of their wealth, a treasure they locked up in another amphora which they buried next to the flies.
