Devil's Dyke, Hertfordshire

Devil's Dyke is the remains of a prehistoric defensive earthwork situated at the east side of the village of Wheathampstead, Hertfordshire, England [1]. Protected as a Scheduled Monument, it formed part of the extensive fortifications of a major Iron Age settlement belonging to the Catuvellauni tribe of Ancient Britain [1]. The site has possible associations with Julius Caesar's second invasion of Britain in 54 BC [1]. Recent archaeological investigations have revealed it as one of the largest prehistoric earthworks in the region, representing significant defensive infrastructure of late Iron Age Britain [1].
