Since 2000, the Sunnerby project has conducted archaeological research with annual excavations on Kållandsö in Västergötland. An aristocratic habitat including a hall building from the Younger Iron Age and graves on the adjacent burial ground have been investigated as well as the remains of a medieval church and cemetery. One of the investigated graves is Kungshögen, a large mound from the 6th century. It is important to note that similar burial environments have not been investigated archaeologically before in western Sweden. The hall in Sunnerby is contemporary with Kungshögen and it is easy to imagine that one of the men buried in Kungshögen sat as a chief in the hall. The hall has been a magnificent building, about 11.5 m wide and over 40 m long with large posts that in pairs carried the roof. From the traces in the ground we understand that the building was of impressive size and fully comparable with similar buildings from aristocratic environments in the rest of Scandinavia. We only have a few examples of aristocratic habitats with hall buildings in the West Swedish context. After 13 years of archaeological research, it is now time to summarize and present the results.
