This study about Norrland’s hillforts has been a way to understand and figure out how the hillforts has been used. By reading previously published literature around mostly Scandinavian hillforts and what they may have had for functions and dating, if the assumed previously functions in Norrland was right or if there could be more to them. In this study it shows that functions for hillforts is mostly assumed with none or a few archaeological evidence. The first assumed function of Norrlands hillfort as refuge has been criticized by authors from Norway and Finland because of the distance between district and hillfort. The assumption suggested that it would have been too difficult to flee from an enemy if a raid would be of essence, and with published literature, GIS-analysis, and 3D pictures this can hopefully be shown for the reader.
