Zooarchaeological material from prehistoric settlements usually make up a large amount of the archaeological record. Despite this, research on the material is seldom utilized to its full potential. This is very much the case for the famous iron age settlement at Helgö. Therefore, in this thesis animal bones recovered from building group 4 at Helgö were analyzed using both osteological and taphonomic, as well as spatial variables as a mean to gain a better understanding of various aspects of the settlement and life at prehistoric Helgö. The results from the zooarchaeological analysis provide insight in social activities and practices concerning both human and animal interactions. The animals are found to have been an important part of the lives of the people at Helgö. Both spatial and structural differences in the material reveal various attitudes towards the animals and bring to light a diversity of activities and practices surrounding the settlement and Helgö.
