Opus doliare: tegole e mattoni, bollati o verificati, dai territori di Nurallao e Isili

Several fragments of tiles and brick with about thirty stamps or signa, unpublished or already known in the area between Usellus and Serri, have been found in the territory of Nurallao. This suggests an intensive exploitation from the late republican age until perhaps the late empire of the numerous clay pits which are in the area, presumably related both to the foundations of Valentia, Uselis and Biora (with civilian and military purposes) and to the continuous human settlement in the area
