Scientific attention to rural construction and, specifically, to construction technologies used in suburban areas of a "minor" nature and without any "monumental" connotation, dates back to relatively recent years. But the texts relating to these researches, albeit with a view to progressive increase in scientificity, often do not go beyond a simple report of the discovery and a summary report of the investigations conducted. This volume is therefore not a mere catalog of archaeological evidence relating to the different building techniques present in the rustic buildings identified in the territory of the Po Valley. Its thematic core is in fact a critical and "problematic" treatment of the question, which is not limited to a mere listing of the excavation data available but which, on the contrary, starting from the better known situations and contexts, allows to draw a broad overall picture breath of the situation as well as to elaborate a coherent technical-typological classification of the various building practices attested in the area. It is therefore a valid research tool for the purposes of a wider historical and archaeological analysis of the methods of processing and development of the building techniques themselves, their marked characterization from the point of view of the natural environment, the specific social needs. and economic which have led to their adoption in certain contexts. The result is a systematic and complete typological framework regarding the rural construction of the Mediopadana area, constituting a valid and useful reference model applicable to the various archaeological contexts with an extra-urban settlement character in the region.
