age and, for many centuries, to have been taken as marking the western edge of The Fens. There, the consensus begins to break down.
Likely purpose
In the
eighteenth century ,William Stukeley described it as acanal used for transporting goods and that idea is still promulgated: For example, excavations atWaterbeach in the 1990s by the archaeology unit of Cambridge County Council found what were seen as the remains of a Roman-era boat and cargo of pottery fromHorningsea . [http://www.cambridgeshire.gov.uk/leisure/archaeology/outreach/sites/site_southcambs.htm Car Dyke, Waterbeach] Cambridgeshire Archaeology Unit, accessedAugust 21 2006 ] This stretch has been protected as a scheduled ancient monument. Other archaeological investigations for the same period have foundcoal from the Midlands in use to dry Fenland grain and claim this as evidence of trade and transport along the Car Dyke. [Forbes, R J (1966): "Studies in Ancient Technology". Brill Academic Publishers, Boston, Mass. ISBN 90-04-00626-5.] At its northern end accounts of Roman Britain describe it as an extension of theFoss Dyke , an accepted transport route. ["Roman Britain" (2001).

topography suggests that its use as a canal was unlikely: The segment which ran and to some extent still runs through the Soke, now City, ofPeterborough rises from theRiver Nene to a ridge at Eye then falls to the Pryor, Arnold.

Given the length of the canal, however, modern surveyors suggest that the original engineers "lost their level" at points along the course and these natural barriers were left in place to maintain the required depth of water.

Conversely, the southern half of its passage throughLincolnshire and its northern end, near Washingborough, are accepted as having had a raised bank on each side. However, the one on the upland side would not be a feature well adapted to a catchwater drain.One conclusion, though given the conflicts in the surviving evidence one not reached by everyone, is that overall it was used primarily as a boundary, (as part of it in south Lincolnshire undoubtedly was in the medieval period) but that parts were adapted to serve also as a catchwater drain. Although possibly not originally intended as a means of transporting goods, archaeology has demonstrated that, at some parts at least, it was used by cargo-carry vessels. It is possible to trace features which could be interpreted as boundaries all round The Fens which are either of Roman date or natural. The exception is in the south-east of The Fens where the landscape was manually strip mined for
phosphate so destroying any evidence, before the days of detailed mapping andaerial photography .In his historical novel "Imperial Governor", ISBN 0-432-14750-0,
George Shipway maintains thatGaius Suetonius Paulinus , then governor of Britain, conceived draining the fens as a way of denying Icenian rebels a place to hide.Fens Waterways Link
The section between the rivers Nene and Welland may be restored to navigation as a section of the new
Fens Waterways Link for leisure craft. An engineering study has been made, but because of concerns for its historic status it is not the preferred route. [cite web
