Orkney's Ness of Brodgar dig resumes after radar reveals mysterious find
Archaeologists will return to the Ness of Brodgar in Orkney next summer after ground-penetrating radar uncovered an "extraordinary" and unexplained structure, unlike anything previously found at the Neolithic site.
Unexpected discovery prompts new excavation
The team, which concluded two decades of fieldwork in 2024, conducted 3D radar surveys this year-marking the first time such technology was used in Scotland. The scans revealed a feature "totally dissimilar" to the site's known architecture, raising questions about its origin and era.
Nick Card, the excavation's longtime director, described the find as potentially "adding a new chapter" to the site's history. Unlike the rectangular Neolithic buildings uncovered earlier, this structure may not even date to that period. "Possibly it is later," Card told BBC Radio Scotland, "but it could be contemporary."
Site's significance and past findings
Located between two lochs near the Ring of Brodgar-a Neolithic stone circle often compared to Stonehenge-the Ness of Brodgar spans three hectares. Previous digs exposed over 40 structures, built in phases from roughly 3,500 to 2,400 BCE, cementing its status as one of Atlantic Europe's most important prehistoric settlements.
The site's architecture is characterized by straight lines and geometric forms, a pattern the new discovery appears to break. "We're not getting into another 20 years of excavations," Card noted, suggesting the find lies in an area with shallower archaeological layers.
Limited excavation planned for 2026
Funded by the Time Team for an upcoming documentary, the new phase will involve "keyhole surgery"-a small trench to investigate the anomaly. The team aims to create 3D models of the site, offering deeper insights into its development.
The four-week dig in July 2026 will be open to the public, though previously excavated buildings remain covered for preservation. "We always said fieldwork was over," Card admitted, "but the geophysics results were too compelling to ignore."
"This was the first time this particular form of GPR had been used in Scotland. The preliminary results have just been amazing."
