Devil's Ditch, also known as Reach Ditch or Fleam Ditch, is a substantial linear earthwork running approximately six miles across the Cambridgeshire landscape between Reach and Woodditton. The monument consists of a deep ditch with associated banks, forming a defensive barrier that controlled movement across the chalk uplands of the region. Dating evidence suggests construction in the late Iron Age, possibly the first century BC, though the ditch may have seen continued use and modification into the Roman period and beyond. The earthwork's precise military or territorial purpose remains debated among scholars, though it likely served to regulate access across important routeways or to demarcate a boundary zone between adjacent settlements or polities.
