This thesis compares four excavated ritual places that have been connected through place names to the two Norse gods Týr and Ullr. The purpose is to contribute to the discussion about the nature of Týr and Ullr and their relationship. Excavation reports, primary sources and other publications are used as material to achieve this purpose. A qualitative method is used in the comparison between the ritual places. The conclusion is that Ullr probably were a sun god and law god with connections to aristocracy, war, rings and possibly horses, but that he also changed through time. The relationship with Týr remains obscure though, partly because of the limited material, but the two gods seems to have had similar connections to aristocracy and war. Both gods may also have survived into the Viking age. The presence of other gods such as Freyr and Odin makes the tracing of Týr and Ullr more complicated.
