This study is a historical archaeological analysis of a territorial area including the Island of Elba, Monte Pisano and the neighboring plain, using the methodology of 'light' archeology: stratigraphic reading of the elevations and reading of the historical landscape. The purpose of the study was to analyze, within the territory under consideration, the spread of a religious building (TE 1) and understand the reasons behind the choice of a specific architectural language, even in political and cultural contexts very different from each other, by both religious and lay clients who chose to represent their prestige in this way.
