The Ruju is definitely the most famous Nuraghe in Chiaramonti.
The imposing single tower has a truncated-conical shape and large masses were used to build the base which gradually reduce in size as the building rises.
The access door leads into the central chamber featuring three side cells and protruding rows which end in a cupola. A spiral staircase leads to the upper floor where the elevation of the second room is still visible.
Built with well squared trachyte masses, it is clearly visible from the trunk road SS 672 which links Sassari to Tempio.
