This thesis builds upon previous research into the built environment in South Scandinavia by focusing on Neolithic timber circles, with a particular emphasis on those from the Middle Neolithic period (c. 3300-2300 BCE) and the Late Funnel Beaker Culture. Architectural remains are pivotal in archaeological research as they provide crucial insights into past communities. By examining the construction practices of timber circles, this thesis explores the complex relationship between building materials such as posts, flint, pottery and structural design, highlighting their role in the dynamic and temporal process of creating these structures. The analysis is guided by a theoretical framework that emphasises the temporality of structures and considers timber circles as assemblages of heterogeneous elements. This is a doctoral thesis in Archaeology with General Specialisation at Stockholm University, Sweden 2025.
