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.

This thesis project explores landscape and the transformations that occur to it over time. Using architectural interventions the project sets out to find a way of narrating and emphasising the transformation processes that take place in the landscape, striving to challenge and deepen the understanding of both man’s and nature’s impact on the environment we inhabit. With the backdrop of the city of Uppsala and the well documented findings of Carl Linnaeus’ field studies along his herbal excursion trails called the Herbationes Upsaliensis, this project takes a closer look on one of the trails, the Ultuna trail.  From investigating the trail, a selection of stories representing different types of landscape transformations that have taken place along the trail, has been made. By introducing an alternative trail parallel to the Ultuna trail, lined with architectural interventions, the objective has been to present the Ultuna trail from new perspectives, creating a new way of experiencing of our surroundings.
