It has always been out of question to write the history of Roman Britain without mentioning the Hadrian's wall. Sadly, it has been often typical to write the history of the Scandinavian kingdoms without mentioning the Danish wall of Danevirke and the Swedish Götavirke.

The historical importance of these walls have been underestimated, and the interpretation of Scandinavian history has lost important aspects, such as understanding the conflict between the Christian Frankish empire and Norse Scandinavia as a cultural conflict.
