The Durotriges, ‘fort dwellers?’ or Durotrages ‘fort runners?’, were a close-knit confederacy of sea-faring peoples in the south-west who controlled two major harbours, Poole and Christchurch, and traded with Armorica. Their territory closely matched that of Anglo-Saxon Wessex, centred on Dorset and defined by the rivers Avon, Wylye, Brue, Yeo and Parrett. Coins made at Hengistbury Head and elsewhere.
