- Abstract
- The aim of this paper is to present the results of the research undertaken through a series of on-site surveys (2021-2023) at the Sasso Pinzuto site, located approximately 1 km SE of Tuscania (Viterbo, Italy). Situated along the eastern side of the Marta river valley, the necropolis layout is little known but it is extensive, including ca. 100 rock-cut chamber tombs. The 2021-22 archaeological campaigns started with a new topographical survey of the site and investigated two areas conventionally defined the Northern and the Southern Area. In the Northern Area, specifically within the vicinity of Tumulus 1, fragments of mould-decorated architectural plaques from a building discovered. In the Southern Area, a small plateau about 90 m from the Northern Area, four burial graves (n. 126, 127, 128, 130) and two chamber tombs (125 and 129) were excavated. This study sheds light to the great potential of applying digital technologies for a new understanding of the Etruscan tombs. Indeed, by using various non-destructive prospecting methods (aerial photogrammetry, fieldwalking survey, architectural drawings), coupled with precise location using RTK GNSS, and integration of legacy data in GIS, the site underwent a comprehensive reexamination.
