Car Dyke is a linear earthwork of Roman date that runs for approximately five miles across the Lincolnshire fens, extending from near Waterloo to Walton in the parish of Walton-on-Trent. The dyke comprises a substantial bank with an accompanying ditch and appears to have functioned as a boundary or defensive line during the Roman period, likely dating to the first or second century AD. Its precise purpose remains debated among scholars, though it may have served to regulate movement across the fenland landscape or to mark the limits of Roman territorial control in the region. The monument survives as an upstanding earthwork in places, though its form has been considerably altered by subsequent agricultural activity and drainage schemes associated with the post-medieval reclamation of the fens.
