Spatial organisation within the earliest evidence of post-built structures in Britain

Led by researchers from the University of York, Dr Jess Bates, Dr Aimée Little and Professor Nicky Milner, and Prof Chantal Conneller from Newcastle University, the study provides evidence of organised activity areas inside a structure found at the early Mesolithic site of Star Carr, North Yorkshire.

At least three post-built structures were excavated at Star Carr during excavations from 2004-2015. By analysing the microscopic use patterns of stone tools found in and around the structures, a range of activities were interpreted including evidence of wood, bone, antler, plant, hide, meat and fish working. These results were then plotted spatially so that zones of activity could be examined.

Within one structure, a combination of microwear and spatial data indicated that the working of some materials was more spatially restricted than others. The findings revealed that Mesolithic inhabitants of Star Carr were organising space within this structure in particular ways, potentially creating areas of different types of activity. For example, messier activity involving butchery was spatially distinct from crafting activity. From this, it is possible that those who used the space were aware of the social norms that may have defined where each respective task should be undertaken.

Star Carr, a site of international archaeological importance, provides the earliest known evidence of post-built structures in Britain. These results contribute to our understanding of early forms of architecture in Britain and why hunter-gatherers were building structures throughout the Mesolithic period. Currently, very little is known about Mesolithic structures and how they were used. Conclusions from this study highlight the rich potential of micro-scale analysis when applied to these important spaces.
