The first area of settlement in the village was to the extreme south of the current village, close to current road junction of the Cambridge and Kings Hedges Road (once called Arbury camp this land has now been developed as part of the large Orchard Park housing development). There was a large Iron Age fort here that was built by the Iceni to defend against the invading Celts this was taken over by the Romans later on, the main evidence left today of the Roman occupation is the Roman road, Akeman Street (known locally as the Mereway), this cuts through the edge of Impington and heads for The Fens, this route had fallen into disuse by the 11th century.
