Presented are results of the first three years of the Falerii Novi Project (FNP), an international archaeological research initiative to explore the ancient urban site of Falerii Novi, in the Comune of Fabrica di Roma (Viterbo, Lazio), in the middle Tiber Valley. According to sources, Roman Falerii Novi was founded in the mid-third century BCE, when the nearby Faliscan center of Falerii Veteres (modern Civita Castellana) revolted and was conquered by Rome. The site, measuring nearly 32 ha, lies along ancient via Amerina, approximately 50 km north of Rome. The only standing premodern remains are the city-walls, generally dated to its foundation, an extramural amphitheater to the northeast, peri-urban tombs, and the complex of Santa Maria di Falleri, whose monastic community is first mentioned in the 11th century CE. Previous work in the nineteenth century and limited excavation carried out by the Soprintendenza during the late twentieth century remain largely unpublished. More recently, non-invasive work using magnetometry and Ground-Penetrating Radar (GPR) has generated plans of the subsurface remains of the Roman town. The interim results of the FNP presented here build on this remote sensing program to provide more detailed understanding of the site’s development over its full history. We describe results from an initial campaign of test pits (2021) and two years of open-area stratigraphic excavation (2022–23). Pursuant to our aims of exploring a range of urban spaces, trenches have been excavated across the intramural area, guided by the remote sensing results. Four areas of excavation are discussed below, including a macellum (Area I), an urban domus (Area II), a commercial area along the via Amerina (Area III), and a series of tabernae beside the forum (Area V). A final area discussed (Area IV) represents a restudy of unpublished excavations undertaken by the Soprintendenza.
