Borre in Norway is famous for its Late Nordic Iron and Viking Age (AD 400–1050) monumental burial mounds. Recently, ground-penetrating radar (GPR) surveys have revealed three large structures close to the mound cemetery. Their unusual layout and size, and location within such a prominent burial site, suggest that they were halls—high-status buildings mentioned in the Nordic sagas. The authors present the GPR results, discuss the buildings’ typological classification and provide a preliminary chronological framework. The latter suggests that the buildings coexisted with some of the burial mounds, and raises important questions about the significance of such buildings in Nordic mound-building societies.

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.

Landscape geophysical survey around the small upland ‘henge’ at Yarnbury, Grassington, North Yorkshire revealed few anthropogenic features around the enclosure but did identify a small rectangular structure in the same field. Sample trenching of this feature, radiocarbon and archaeomagnetic dating proved it to be an earlier Neolithic post and wattle structure of a type that is being increasingly recognised in Ireland and the west of Britain. It is the first to be recognised in the Yorkshire Dales and it is argued that the Dales may have been pivotal in the Neolithic for east–west trade as well as pastoral upland agriculture.
