Grim's Bank is a linear earthwork of Anglo-Saxon date located in Old Warren, Berkshire. The monument consists of a bank and ditch running for approximately 880 yards (795 metres), forming part of a larger system of linear defences that may have served territorial, administrative, or defensive purposes during the early medieval period. The earthwork's precise function remains subject to scholarly interpretation, though such linear banks are commonly associated with land division, boundary demarcation, or protection of settled areas during the Anglo-Saxon centuries. The surviving section preserves important archaeological evidence of early medieval landscape organisation in the region.
