Birkas norra hamnområden : Arkeologiska undersökningar av maritim lämning inom Gravfält L2017:1904, Birka, Björkö, Adelsö sn, Up., maj 2022

• This report presents the results of archaeological investigations of maritime remains on the northern part of Björkö in Lake Mälaren, in connection with L2017:1904, Adelsö parish, in Uppland. The investigations included surveys, geochemical analyses and excavations as well as a topographic investigation of the so-called Salviksgropen. The results of a ground penetrating radar survey and an osteoarchaeological analysis of the bone material from the 2020-2021 excavations of a shipyard site are also discussed. The investigations were carried out by the Archaeological Research Laboratory, Department of Archaeology and Classical studies at Stockholm University. The results show that the stone row, which in the previous survey was referred to as the possible remains of a jetty or boat landing site, probably constituted a breakwater, as well as a landing site, that was constructed to protect the adjacent shipyard site. The osteological analysis shows that the bone material consists of food remains, and a possible place for food preparation is indicated by the soil chemical analyses. The same analysis also points to a possible site for blacksmithing activities associated with the shipyard site. The georadar survey shows traces of ploughed-over burial mounds, indicating that the cemetery Hemlanden surrounded the shipyard site on all sides. The height mapping of the potential harbour arms at Salviksgropen shows that these, as they look today, are too low in the landscape in relation to the maritime remains at Korshamn to have had this function.
