The first results of geophysical prospections using the ADC method on the proto-urban settlement site Como, Spina Verde

This article presents preliminary results of the first geophysical surveys and a rescue excavation in the area of the extensive late prehistoric Early and Late Iron Age proto-urban settlement of Como/Comum on the Spina Verde ridge towering over the present town. Two short susceptibility surveys demonstrated that this impressive site can be successfully prospected using both geomagnetic and georadar technology and above all by combining their results. We initially demonstrated the susceptibility of the Spina Verde ridge for geophysical prospection in the environs of the excavated Pianvalle site. The results of the following survey of a meadow on the Via Isonzo were remarkably clear, and if the structures are indeed prehistoric, they indicate the presence of a monumental “Casa Alpina”-like cellared building and possible rectilinear walled enclosures. Complementing these findings are the results of a rescue excavation monitored by the Soprintendenza for the province of Lombardy in the Via Ronchetto. Here, the massive walls of a cellared alpine-style building were recovered. We hope to continue surveying in prehistoric Como in order to make a comprehensive plan of this remarkable site.
