Offa’s and Wat’s Dykes

David Hill and Margaret Worthington Hill’s Offa’s Dyke Project made a sustained contribution to the study of both Wat’s Dyke and Offa’s Dyke. To celebrate and reflect on this legacy, we have secured permission to reproduce David Hill’s 1991 book chapter ‘Offa’s and Wat’s Dykes’ in the Offa’s Dyke Journal. The article has been edited for style and includes a new introduction, re-drawn maps, the original section drawings, plus one of the original photographs. Citations have been added to key works available at the time of Hill’s writing. Further citations have been added to help readers link Hill’s arguments to more recent publications. Published electronically for the first time, we hope Hill’s work reaches new audiences and re-energises the enthusiasm and efforts of enthusiasts, students and specialists alike in Britain’s longest early medieval linear earthworks.
