The Car Dyke was and to large extent still is, a ditch which runs along the western edge of The Fens in eastern England. It is generally accepted as being of Roman age and for many centuries, to have been taken as marking the western edge of The Fens. There, the consensus begins to break down. The Fens may also refer to the Back Bay Fens, park in Boston, Massachusetts. ...

Likely purpose

In the eighteenth century, William Stukeley described it as a canal, used for transporting goods and that idea is still promulgated but is demonstrably very unlikely. It has causeways of never-disturbed ground crossing it and it passes in gradients, up and down the sides of slight ridges. It is said to be a catchwater drain and so it undoubtedly is but only in parts. The southern half of its passage through Lincolnshire and its northern end, near Washingborough, are accepted as having had a raised bank on each side. That on its upland side was not a feature well adapted to a catchwater drain. (17th century - 18th century - 19th century - more centuries) As a means of recording the passage of time, the 18th century refers to the century that lasted from 1701 through 1800. ...

The inevitable conclusion, though not one reached by everyone, is that overall, it was designed primarily as a boundary, that parts were adapted to serve also as a catchwater drain and that parts, such as that near Peterborough, are a little older, were designed as a catchwater drain and were incorporated into the overall scheme, having been designed as catchwater drains. It is possible to trace boundaries all round The Fens which are either of Roman date or natural. The exception is in the south-east where the landscape was manually strip mined for phosphate so destroying any evidence, before the days of detailed mapping and aerial photography. Peterborough is a city in the east of England. ... Strip mining is the practice of mining a seam of mineral ore by first removing all of the soil and rock that lies on top of it. ... In chemistry, a phosphate is a polyatomic ion or radical consisting of one phosphorus atom and four oxygen. ...
