Devils Dyke

Devil’s Dyke is the largest of several earthworks in south Cambridgeshire that were designed to control movement along the ancient Roman roads. When it was created, it completely blocked a narrow land corridor between the southern edge of a region of water-logged marsh (now known as The Fens) in the north-west and dense woodlands in the south, so making circumvention difficult and forming an effective defensive barrier for the lands to the east. The dyke crossed three important Roman roads, including the ancient Icknield Way, and may thus have served as a way of controlling trade and movement in and out of the area.
