This is to ensure that important information about the site is recorded, published and archived. We're working closely with Gallagher Estates to make sure that these important archaeological sites are not lost without a comprehensive record which will be available to future generations for study."
Andy Lawson, Projects Director at Gallagher Estates said: "We are nearing the end of a significant programme of archaeological investigation in this part of Northstowe. Cambridge Archaeological Unit have done a great job and their work will contribute to a greater understanding of the history of settlement and activity in the area. Following the completion of the archaeological investigations, we will be pressing on with the construction work across Phase 1."
