The paper deals with the contribution of Landscape Archaeology to the study of a wide stretch of low plain that extends south of the city of Padua, between Euganei Hills and Venice Lagoon. Following an archaeomorphological approach and through the integrated analysis of geomorphological, archaeological and historical data, beside a photo- and carto-interpretation work carried out by exploiting the numerous possibilities offered by GIS, the study tries to understand the complex relationship mankind-landscape established within this area during Roman times.
