Landscape archaeology has contributed greatly to the advance of centuriation studies, a research area widely considered marginal in recent decades. This was due in large part to a multiplicity of unreliable studies from the 1970s to the 1990s, some of which were proved wrong by large-scale excavation. Despite this, the last decade has seen a revival of archaeomorphology-based studies that has helped put this discipline back on the map. Moreover, current research has adopted multidisciplinary approaches which include archaeological evidence, spatial analysis and palaeoenvironmental data. Environmental sources offer important insights on the effects a deductio had on the landscape. The incorporation of new digital methods and Geographic Information Systems (GIS) represents a major qualitative leap forward in the planimetric accuracy of field system restitution, improving the quality and reliability of archaeomorphological analyses. These new methodological advances have been largely developed in the territory of Roman Barcino (Barcelona), an Augustan colony in which the centuriatio embodied the ideal territory of a Roman town. The results allow a move from purely economic or materialistic approaches to more socially and culturally focused explanations. Linking centuriation with Roman settlements and landscape dynamics, our text proposes a rethink of Barcino centuriation which brings out both its economic impact through its influence on land use and the significance of its conceptual and representative dimension.
