A farmer ploughing a field on the Isle of Bute has rediscovered a long-lost Bronze Age burial chamber, dating back approximately 4,000 years. The cist, located at Rhubodach, was first documented before 1863 when a human skull was removed and sent to the Society of Antiquaries of London, after which the site was forgotten. It lay undisturbed for over 150 years until the farmer's plough brought it to light again in 2022, leading to the discovery of further human remains.
An excavation by AOC Archaeology Group confirmed the presence of two individuals within the cist, though they were not buried at the same time. Analysis led by Dr Jess Thompson, Scotland's first curator of osteoarchaeology at National Museums Scotland (NMS), revealed the uppermost individual was an adult male aged 35–50, about 5ft 6in tall and in good health. Beneath him lay the remains of a female, likely an adolescent or very young adult. Both skulls are missing, as 19th-century practice often involved recovering only the cranium.
Radiocarbon dating and isotopic analysis indicate a predominantly terrestrial diet with little marine protein. Dr Thompson noted: 'The radiocarbon dates indicate that they died within the final quarter of the third millennium BC, so after 2250 BC, and that the uppermost individual probably was buried just after, or up to a few generations later than the lower individual. And so probably this cist was used within the living memory of these individuals.'
The finds were declared through the Treasure Trove Unit and allocated to NMS in September this year. They are now housed at the new state-of-the-art National Museums Collection Centre in Granton, Edinburgh, which became operational in autumn 2025. The facility, part of the Scotland's Archaeological Human Remains Collections (SAHRC) project, provides a 70% increase in storage capacity for human remains from around 2,500 individuals across approximately 600 archaeological sites in Scotland.
Dr Matthew Knight, senior curator of prehistory at NMS, highlighted the importance of the rediscovery: 'The cist was found at a site called Rhubodach on the Isle of Bute, and it's a cist that had been forgotten about. It had actually previously been excavated in the 1800s when a skull was recovered and sent to London. ... The skull, unfortunately, has now been lost, but rediscovery and re-excavation of these remains is allowing us to reinterpret and retell the story of this individual.' He added that the SAHRC project ensures ethical care and curation of these remains, treating them with the utmost respect.
