The Museum of Prehistoric Statues in Sardinia is situated within the Palazzo Aymerich, the last abode of the marquises of Laconi.

The museum route, furnished with extraordinarily interesting scientific testimonies, weaves its way through eleven rooms distributed throughout the first two floors: ten rooms are dedicated to menhirs and to the great anthropomorphic statues from prehistoric, central-southern Sardinia (Sarcidano, Grighine and Mandrolisai). The eleventh room, la galleria, or “the gallery”, opens onto the large internal courtyard and hosts archeological finds of material culture recovered from among the funerary megaliths of Sarcidano. 
The menhirs on exhibition consist of three different typological classes:

• “proto-anthropomorphic”, which feature an ogival shape but are void of figural representations;
• “anthropomorphic”, which instead present features characteristic of the face, eyes and nose;
• and finally genuine “statue-menhirs”, which clearly evolved from the anthropomorphic but asexual menhirs, and which are detailed and symbolically rich, allowing for a distinction between the two sexes. 

Among the pieces on view, the specific sizes and iconographic expressions differentiate the 36 monoliths of Laconi from each other, all of which were sculpted from local trachyte excavated from various regions of the territory (such as Mind'e Putzu, where a genuine prehistoric cave has been identified). The other specimens stand out with respect to their peculiar iconographic symbolism which is notably different from the symbolism expressed by the menhirs of the area around Sarcidano.
