The Car Dyke
By Brian Simmons and Paul Cope-Faulkner, this booklet describes the route and appearance of The Car Dyke today and looks at investigations and excavations that have taken place on it over the years.
The Car Dyke is a Lincolnshire and Cambridgeshire mystery. It is an ancient, artificial watercourse extending for over 57 miles (92 km) from Washingborough, near Lincoln to Peterborough. In 1712 the Historian John Morton, suggested that it was constructed by the Romans for drainage of the Fens and as a navigable canal. Nearly 300 years later, despite much historical research and many archaeological excavations we are still unable to prove or disprove his theory. That said we now know much more about it – The Car Dyke is generally between 12 and 17 metre wide and 3 to 4 metres deep with a similar profile for all its length. It is flanked blow banks formed from the excavated material and in parts it is lined with clay. It is not continuous – excavations have shown that roads and tracks crossed it occasionally on causeways left undug and which may have been simple locks.
This booklet describes the route and appearance of The Car Dyke today and look sat investigations and excavations that have taken place on it over the years. It considers who build The Car Dyke, and why, and examines current threats to the monument and its future potential for tourism and recreation.
