The construction logic, that was well documented in the Nuragic era in the sanctuary village of S’Arcu’e Is Forros, located in an areas of central-eastern Sardinia, strongly characterised by limestone, granite and schist reliefs, was to use the nearest stone to the building location and therefore immediately available.

One of the most important aspects is the compactness the materials, that has allowed good preservation of structures.

The stones of various shapes and sizes have produced a mixed type of architecture.

For example, in the sacred area, granite was used, as in most nuraghi in the area, to create walls made of irregular rows, of different sizes (fig. 1).

On the other hand, it can be seen how the schist, a soft rock that is easy to work, was used in the top part, i.e. for the roof of the entire temple structure, perhaps chosen for its sunlight refraction qualities (fig. 2).

The expertise achieve in working the limestone emerges, instead, from the accessories closely connected to the place of worship: bases were found, for example, with holes that were intended for the insertion of votive bronzes (fig. 3).
