This work summarizes and presents the results of three years of research conducted in the territories of the Tuscan-Emilian Apennines, with particular attention to the areas within the limits of the province of Reggio Emilia. The main object of the investigation is medieval domestic architecture, both those still preserved at high altitudes and those that emerged during the archaeological excavation campaigns, from those more dating back over time to the late medieval turn. Attention was paid not only to a typological study of architectural models and their evolution, but also to understanding the potential basin of information that this particular type of source represents for the social, economic, settlement and cultural history of the territory. It is essentially a study by archeologia dell’architettura which does not intend to limit itself to classical themes, but rather is proposed as a meeting point between the analysis of the elevations and the archeology of the landscape. Through the study intertwined between archaeological evidence and written sources, some peculiarities of the Reggio Apennines have been brought to light, deriving from the events that shaped the human communities that inhabited it over the medieval centuries. The extension of the methods typical of the archeology of the elevations, already abundantly used in the study of churches and castles, to the so-called "minor" structures of the architectural landscape has made it possible to understand with greater clarity the relationships and social structures that came to be determined. from time to time, in the face of changes in the political order of the territory.
