Arkeologiska undersökningar av Birkas försvunna stadsvall, fornlämning L2017:1568, Raä 119:1, Svarta jorden, Björkö, Adelsö sn, Ekerö kn, Uppland, maj 2018 och maj 2019

• This is a report of archaeological investigations, excavations and geochemical propections, in search for the today lost part of the town rampart of the Viking Age site Birka in eastern central Sweden, conducted by the Archaeological Research Laboratory, Stockholm University, in 2018-2019. The results show, for the first time ever, evidence of a town rampart with an associated defensive ditch in the investigated portion of the town perimeter. This is inferred to be the result of deliberate choices to build different types of defensive structures with regard to the varying terrain in different sections around Birka, indicating explicit tactical considerations when choosing construction technology.
