Results of a Field Evaluation Survey on Skomer Island, Pembrokeshire

A non-intrusive field evaluation was undertaken between 7-9 May 2024 on Skomer Island, Pembrokeshire. Fieldwork comprised systematic walkover survey, surface inspection, GPS recording, measured offsets, and photographic documentation to map and describe features and artefact scatters associated with prehistoric settlement activity. At selected hut sites, including Huts 12, 16, 21, 34 and 35, detailed topographic observation and sketch recording were used to document burnt mound morphology and relationships to associated roundhouses and field boundaries. Criteria were developed in situ to distinguish heat-shattered material from naturally fractured volcanic stone. During the same event, lithic scatters and isolated finds were recorded using GPS and digital photography. No excavation or intrusive sampling was undertaken. Lithics located on active paths judged at risk of damage were collected for safekeeping, with all others left in situ. The work was carried out with permission from the Wildlife Trust of South and West Wales, following standard University of Bristol Department of Anthropology & Archaeology field recording procedures. The field evaluation enhanced understanding of the prehistoric occupation of Skomer Island by documenting several probable burnt mounds associated with roundhouse settlements and identifying new lithic scatters indicating on-site knapping and domestic activity. Survey results confirmed that multiple burnt mounds were constructed in close proximity to habitation structures rather than beside water sources, suggesting non-industrial or ritual use, possibly linked to sauna or display activities during the Iron Age. Two substantial flint waste scatters and a convex scraper were recorded near Hut 16, with additional flint finds at Captain Kite's Corner and along the path to North Haven, implying the import and working of beach flint within a closed island landscape. No excavation was undertaken, but the findings demonstrate that prehistoric activity on Skomer was more extensive and complex than previously documented, with evidence for hot-stone technologies, tool production, and structured settlement use across the island.
