Abstract

Urban geology analyses natural risks and promotes geoheritage in urban areas. In the cities, characterized by a high cultural value,the hypogean artificial cavities, often present in the downtown, offer a unique opportunity to show the geological substratum.Moreover, these places could be a point of interest in urban trekking with the abiotic component of the landscape as a topic(geotourism). To investigate these areas, rigorous bibliographic research and a geomorphological assessment are the first steps,but, besides, non-invasive methods are new techniques increasingly in demand. In this paper, we present a multidisciplinarystudy on the Etruscan Well (third century B.C.), one of the most important Etruscan artefacts in Perugia (Umbria region, CentralItaly). The characteristics of the sedimentary deposits outcropping along the perimeter walls have been collected. Moreover, toshow the underground geoheritage, we provide a 3D model of the well and the surrounding area integrating a georeferenced laserscanner survey with ground-penetrating radar prospecting. We aim to obtain a tridimensional mapping of accessible internalrooms to depict the geological characteristics of the Etruscan Well, also revealing a surrounding network of buried galleries. Theresults are not only a meaningful advancement in the archaeological, geological and historical knowledge of the downtown ofPerugia but are a hint for the geoheritage promotion and dissemination, providing images and 3D reconstruction of undergroundareas
