Cambridge Archaeological Unit undertook a trenched evaluation on land to the north of Cambridge Airport, Fen Ditton, Cambridge, prior to the proposed redevelopment of this area. A limited amount of archaeology was identified within the western half of the PDA, which included a metalled Iron Age trackway and several track-side ditches. Within the eastern half of the PDA however, significant archaeological remains were identified including an area of probable early prehistoric activity; a concentration of Late Bronze Age/Early Iron Age ditches; and a small Late Iron Age/Early Roman settlement.
