As the Iron Age gives way to the Romans there is much more evidence and information of Roman occupation in the Wimpole parish. First of all, at the western end of the Wimpole parish there is a Roman road called Ermine Street (A1198 formerly the A14). This still runs straight as a gun barrel from Royston to Caxton. The Wimpole parish boundary to the south is the river Rhee and to the south west is Arrington Bridge At the southern end of the parish, cutting through the parish, is Cambridge Road (A603). This actually used to be called Cow Street in the 17th century and almost certainly was constructed by the Romans.
