Grims Ditch is a prehistoric linear earthwork consisting of a bank and ditch that runs across the chalk uplands of Hertfordshire. The monument dates to the Iron Age, though some sections may have earlier origins in the Bronze Age, and represents a territorial boundary or defensive feature characteristic of prehistoric land division in southern Britain. The surviving sections exhibit the typical form of a substantial bank with an accompanying ditch, cut into the underlying chalk and creating a prominent landscape feature that would have been visible for considerable distances across open downland. As a linear monument of this period and scale, Grims Ditch provides archaeological evidence for the organized use and demarcation of land during the later prehistoric periods.
