Devil's Dyke or Devil's Ditch is a linear earthen barrier, thought to be of Anglo-Saxon origin, in eastern Cambridgeshire and Suffolk. It runs for 11 kilometres (6.8 mi) in an almost straight line from Reach to Woodditton, with a 10-metre-high (33 ft) ditch and bank system facing southwestwards, blocking the open chalkland between the marshy fens to the north and the formerly wooded hills to the south.[1][2] It is a Scheduled Monument, a biological Site of Special Scientific Interest and a Special Area of Conservation.
