The intent with this paper is to investigate the medieval habitation in central Old Uppsala. This time-period has over the years been neglected. Therefore I wish to summarize and ana-lyze the medieval habitation to see what can be said about its continuity, and also to investi-gate why it is located in certain areas. Due to the amount of source material I have limited my investigation area to the central Old Uppsala. It is possible that this limitation will affect the result of the research but without the limitations the investigation area would have been too large to handle. The source material has been collected from excavation reports and the summarized. My theory is material culture and material agency. It is the material culture that I analyze. The result of the investigation is that it is possible to see a continuity of the habitation in the area but that it’s hard to get an exact date on many of the structures. One of the reasons for this is because of how the medieval time period have been handled by archaeologist. As to where in the landscape the buildings have been placed there seem to be some places that have been avoided and others that have a long continuity of buildings over time. / Gamla Uppsala - framväxten av ett mytiskt centrum
