Nuraghe Losa is one of the larger nuraghi. Around the nuraghe there are traces of a nuraghe village and wall. The nucleus of the prehistoric structures is composed of a complex tholos nuraghe, the top floor of which has fallen. On the southern side of the nuraghe we find a round hut. The floor plan shows a trilobate structure consisting of a main trunco-conic tower around which are three similar but smaller towers, together forming a massive bastion.
