The Mannu Nuraghe, located in the upper part of the town, is built entirely of rough-hewn trachyte boulders and has a circumference of about 11.5 meters. The monument has a residual height of 6 meters and preserves a circular chamber that originally had a tholos roof, i.e., a false dome made of concentric rings of overlapping stones with a progressively smaller diameter. The chamber, currently preserved up to the height of the niches, is occupied by an imposing collapse. The presence of an upper chamber, now no longer visible, is not ruled out, which would lead to the assumption of an overall height of no less than 12 meters. Around the tower wall sections and unevenness in the ground are identified, suggesting the existence of other structures, for now not clearly definable but in all probability pertaining to a village.
