The University of the Highlands and Islands Archaeology Institute have teamed up with Yarrows Heritage Trust to re-commence the community excavation of possible Iron Age structures at the Burn of Swartigill on 20th August.
Located in Caithness, the site was excavated in 2015 and 2017 and initial finds pointed to the possible presence of a substantial rectangular building and water management features.
During the 2015 fieldwork, a substantial mass of stonework and well-preserved archaeological features were unearthed and it was suggested that the linear wall lines picked up in the geophysics survey may reflect a long building with its long axis at right-angles to the stream. In addition, the building remains also appear to include a well-built circular structure – possibly an early roundhouse. A possible drain feature was also identified indicating an element of water management over and above that required for a purely domestic use. Samples taken from the site may even be able to shed light on the role and function of the site.
It was also established that previously recorded massive blocks of stone that were eroding out of the stream bank were also parts of wall lines and wall faces. Well-made and decorated Iron Age pottery was also recovered in addition to a quern rubber and hammer stone – the latter from the drain feature.
However the most surprising find was a copper alloy triangular fragment with a possible setting for an enamel or glass paste inlay. This would appear to have been a relatively valuable item from something like a brooch and perhaps hints that a certain social status was accorded to the Swartigill site during the Iron Age.
Interestingly, radiocarbon dates suggest that the site was occupied in the period when brochs were evolving in the Northern Scottish Iron Age. It can be tentatively suggested that Swartigill represents an early Iron Age site, occupied before and during the establishment of brochs in the wider landscape.
The site is extremely complex and this year we aim to further explore the social and historical conditions that were present at an important moment of change during the Iron Age period in Caithness.
The Swartigill dig is a community dig. This means that local people are involved at all stages of the process and local volunteers receive basic training in archaeological methods and help with the actual dig. If you want to be involved in this exciting dig then call 01955 651387 or e-mail firstname.lastname@example.org. No experience required!
The excavation commences on 20th August and finishes on 7th September. The site will not be open at weekends this year.
