The Yarnton landscape, extending from the floodplain of the Thames up onto the higher Second Gravel Terrace, has witnessed a long history of topographic and vegetational change linked to human activity. Settlements on the edge of the Second Gravel Terrace were occupied throughout the Iron Age and Roman periods. Associated with the middle Iron Age settlement was a small cemetery of some 35 crouched inhumation burials. Further burials were made in the Roman period. The Roman settlement is marked by its ditched enclosures and small paddocks suggesting intensive stock management, although the presence of an extensive surrounding field system shows that arable agriculture was also intensive, at least in the early Roman period.
