Survey and Sampling at the Castle Dykes Iron Age 'Henge', Wensleydale, North Yorkshire

Abstract

Survey and sampling at the classic single-entranced henge monument at Castle Dykes, in North Yorkshire, has revealed traces of circular timber structures, interpreted as later prehistoric roundhouses, in the immediate vicinity and within the henge. Coring of the waterlogged silts of the internal ditch has produced considerable environmental data: Plant, insect, pollen and charcoal remains. A small jet bead was also recovered. Radiocarbon dates from short-lived materials unexpectedly indicate that the monument was constructed in the Iron Age, which prompts a review of other potentially Iron Age 'henges' further afield.
