Non-destructive 3D prospection at the Viking Age fortress Borgring, Denmark

A multi-method non-destructive prospection at the Viking-Age ring fortress Borgring, Denmark, revealed significant landscape modifications during its construction. The study found that a narrow natural promontory was expanded to accommodate the fortress' rampart, with soil magnetic susceptibility measurements indicating the use of both wetland and upland areas for different compartments. This approach significantly improved the understanding of the fortress' construction and its impact on the landscape, drawing parallels with contemporary sites like Fyrkat. The research combined residual relief modelling from airborne laser scanning data, electromagnetic induction surveys, and coring to create a detailed 3D model of the palaeo-landscape.
