A series of cemeteries located in the area of the later Roman colony of Heba. From the Etruscan period, the locality of S. Maria in Borraccia is famous for an inscribed Etruscan lead plaque dedicated to the sky and the underworld. The rock-cut tombs date particularly from the seventh and sixth centuries (e.g., Poggio, Volpaio, Poggio Bacchino) and may have been the focus of a series of dispersed rural comunities rather than a formal urban area, a status perhaps only achieved once the Roman colony was founded in about 183 BC.
