Four open areas were excavated on land adjacent to Oundle Road, Peterborough Business Park, in order to further investigate areas of archaeological interest identified by field evaluation. The excavation largely confirmed and significantly expanded on the results of the evaluation, revealing agrarian land use from the Iron Age through to the later 3rd century AD, and charting the different agricultural practices reflected by the changing enclosure layouts. In the absence of detailed information regarding the Roman settlement remains on the site of the adjacent Royal Life and Pearl Assurance development, the enclosure system is especially important in helping to identify the status and longevity of this associated settlement. Also in keeping with the evaluation results, only scant evidence of pre Iron Age activity was uncovered, and none dating to the Saxon period.
