Excavations revealed a number of significant finds, including evidence of a rare Viking boat burial, and a second grave richly furnished with weapons including a sword.
Similarities with the type of burials and grave furnishings to those previously uncovered suggest the Papa Westray graves maybe those of first-generation Norwegian settlers on Orkney.
Archaeologists from AOC Archaeology are now working to analyse the discovery using a range of scientific techniques, with the hope of gaining new insights into the life and death of the Viking community in Orkney during the 10th century.
The project will include a detailed programme of osteological work (bone analysis) and radiocarbon dating to help determine the age of the remains, as well as expert conservation and analysis of the grave artefacts that were unearthed.
Dr Kirsty Owen, Deputy Head of Archaeology at HES, said “We are delighted to be funding the work on this exciting project with AOC Archaeology, which we hope will shed new light on the Viking communities in Orkney during the 10th century.
“Many of the Viking burial sites we know of in Orkney were excavated in the late 19th and early 20th century, meaning that we have a rare opportunity to investigate this discovery with the cutting-edge methods and techniques available to us today.
“We look forward to sharing our findings as the analysis continues, which we hope will enhance our understanding of the rich Viking heritage of Orkney and reveal more about the people who lived on these islands over one thousand years ago.”
HES will also be working with the Ancient Genome Project to undertake genetic analysis of the discoveries to determine further information about the individuals in the graves, including genetic ancestry and sex, as well as to gain information on their diet and mobility.
Dr Ciara Clarke, Deputy Managing Director of AOC Archaeology, said: “We are excited to be embarking on this project and look forward to working with HES, and an enthusiastic team of experts including Dr Stephen Harrison of Glasgow University, to record, study and analyse the evidence contained in these Viking Age burials.
