Cambridge students help unearth possible Viking-era ‘execution pit’ on training dig
Archaeologists working at Wandlebury Country Park, cared for by Cambridge Past, Present & Future, have uncovered one of the most significant archaeological finds ever discovered on the site: a burial pit containing the remains of at least ten individuals, dating back more than 1,100 years.
The discovery was made during a student training excavation led by the Cambridge Archaeological Unit, working in partnership with Cambridge Past, Present & Future and the University of Cambridge. What began as a carefully planned learning excavation has revealed compelling evidence of extreme violence during a turbulent period in early medieval Cambridgeshire.
The pit contains a striking and unusual mix of complete and dismembered bodies, including a cluster of skulls, stacked leg bones, and several articulated skeletons, some positioned in ways that suggest they may have been bound. Archaeologists believe the remains may represent the aftermath of a mass execution, a violent skirmish, or a combination of both.
A landscape shaped by conflict
Initial dating suggests the burial may belong to the 9th century AD, when Cambridgeshire lay on a shifting frontier between Anglo-Saxon and Viking-controlled territories. During this period, the region sat between the Saxon kingdom of Mercia and the Viking kingdom of East Anglia, which was conquered around AD 870.
Wandlebury’s Iron Age ringwork, constructed around a thousand years earlier, would still have been a prominent and recognisable landmark at the time. Archaeologists believe this long-established place of gathering and significance may have continued to hold social or symbolic importance into the early medieval period.
The burial pit lies just outside the hillfort earthworks, reinforcing the idea that Wandlebury was not only a strategic location, but also a place where power, punishment, and community life intersected.
An extraordinary individual
Among the remains is one particularly remarkable individual: a young man, estimated to have been between 17 and 24 years old, who stood around 6 foot 5 inches tall, exceptionally tall for the period. His skull shows clear evidence of trepanation, an ancient surgical procedure in which a hole is cut into the skull, likely in an attempt to relieve pressure caused by illness or injury.
Signs of healing suggest he survived the procedure for some time. Researchers believe he may have had a condition affecting growth hormones, which would have made him stand out dramatically among his contemporaries.
The presence of such an individual, alongside evidence of extreme violence and careful but unsettling placement of remains, adds further complexity to the story emerging from the pit.
Learning, partnership, and place
This is the first discovery of human remains at Wandlebury since the 1970s, and by far the most significant archaeological find uncovered through the long-running partnership between Cambridge Past, Present & Future and the University of Cambridge.
For the students involved, the excavation was both a profound learning experience and a sobering encounter with the human stories embedded in the landscape.
Further work is now underway, including radiocarbon dating, isotopic analysis, and ancient DNA research, which may help establish where these individuals came from, how they were related, and whether they were Saxon or Viking. Archaeologists will also attempt to “refit” dismembered remains to better understand how many people were buried in the pit and how the burial took place.
Historic England is supporting further investigation at Wandlebury, including new geophysical surveys, to build a clearer picture of the surrounding area and its use over time.
A deeper understanding of Wandlebury
Wandlebury Country Park is loved today as a peaceful green space on the edge of Cambridge, a place for walking, learning, and connection with nature. Discoveries like this remind us that the landscape carries far deeper histories, shaped by centuries of human experience, conflict, and change.
Through careful stewardship and collaborative research, Cambridge Past, Present & Future continues to protect Wandlebury not only as a place of natural beauty, but as a living record of the past, offering new insights into the lives of those who came before us.
The training digs at Wandlebury are a collaboration between Cambridge Past, Present & Future, Cambridge Archaeological Unit and Cambridge University. We will be holding open days in May when you can come and see the digs in action, and a free talk with Dr Oscar Aldred on April 17th.
