Car Dyke is a substantial linear earthwork of Romano-British date that runs between Washingborough and Common Square in Lincolnshire. The dyke takes the form of a ditch with an associated bank, constructed to manage water flow and control access across the low-lying fenland landscape during the Roman occupation of Britain. Its precise original function remains debated among scholars, though it may have served defensive, administrative, or drainage purposes within the Romano-British settlement pattern of the region. The monument represents an important survival of Roman engineering in the Fenland and continues to be visible as a landscape feature.
