The remains are thought to be those of adolescent to mature males and females. Five skeletons were arrayed around a small circular ditch, with the grave of a sixth skeleton in the centre. Two lots of beads, a shale bracelet and other grave goods were also found, which suggest the findings are Pagan.
The site is now being excavated for other artefacts by Wessex Archaeology, led by Phil Harding, known for his work on Channel 4’s Time Team, while colleagues back at the unit’s laboratory examine the remains and jewellery, which have already been removed.
Phil said: “Given that the Stonehenge area is a well-known prehistoric burial site, it was always very likely some interesting discoveries would be made here. The fact that these round barrows were previously unknown makes this particularly exciting.
“Finding the skeletons also helps us to get a clearer picture of the history of this area. To my knowledge these are the first Pagan Saxon burials to be excavated scientifically in Amesbury. “
Landowner Aster Group is building 14 affordable homes at the redundant brownfield site, which will be available to rent from 2014.
Anna Kear, Aster’s regional development director for Hampshire and Wiltshire, said: “Wiltshire is a treasure trove of archaeology, drawing people from across the world.
"Discovering a burial site in this beautiful county is always a possibility when building affordable homes. We’re working with everyone involved to ensure Phil and his team can investigate this exciting find while the build continues.”
Contractor Mansell, a Balfour Beatty brand, was preparing the site for the build when it made the discovery.
Site manager Brian Whitchurch-Bennett, of Mansell, said: “When we’re working in an area of historical importance we always undertake archaeological investigations to make sure that our construction works don’t damage hidden remains or artefacts. The findings within this particular site really are a one off, we’ve been amazed by the number of discoveries and the level of preservation. It’s certainly a project to remember.”
The archaeologists are expected to be on site for six weeks in total. Footage from the site may also be included in an archaeological production for ITV’s History Channel, due to be aired in January 2014.
