Space age, meet Bronze Age.
Shiny quartz, giant granite stones and a possible cremation got here to light during a dig at the brand new SaxaVord Spaceport readying for rocket launches on the UK’s northernmost island.
Shetland’s SaxaVord plans to host its first space liftoff later this 12 months, pending readiness of its license and the businesses planning to send small rockets to space from Unst, within the far north of Scotland.
“It’s definitely very exciting,” an official with SaxaVord (who asked to not be named) told Space.com of the dig. It can take months at least to learn concerning the finds and to work out how one can protect them, but spaceport officials said they’re committed to sharing the story in a roundabout way for visitors — perhaps using an exhibition or marker.
Company AOC Archaeology was on site at SaxaVord to document a scheduled (protected) radar station for the Second World War; it’s standard practice to do this type of thing while constructing recent things within the U.K., given how dense the archaeological record is below ground. While rigorously digging, AOC found the Bronze Age artifacts by accident as there have been no other known ones within the immediate area.
“We didn’t look forward to finding this Bronze Age thing as well,” said Val Turner, an archaeologist who represents the county at large through a Scottish charity, the Shetland Amenity Trust. (The U.K. has many such charities that record archaeology sites and monitor excavations when development takes place, to make sure cultural heritage is being protected by scientific community standards.)
AOC didn’t return requests for interviews. Representative Katie O’Connell told the BBC that the positioning stands apart on account of its circular zone of highly reflective and white quartz pebbles. (There’s one other circular quartz feature within the Shetland area, but it surely’s newer and Pictish — from the Iron Age that got here after the Bronze, Turner told Space.com.)
Archaeologists also found evidence of cremations (burnt bones) and filing-cabinet sized granite boulders that might have needed several people to maneuver over a brief distance.
The boulders were particularly puzzling, Turner said, as the big stones were buried in order that only the ideas were visible. She cautioned the excavations are at such an early stage that no person knows obviously if the timing of the cremations and boulders coincided. But if that’s the case, “it is sort of possible that they (the stones) were put there so as to create a visible boundary of the world.”
The Bronze Age, very loosely defined, describes an evolving set of cultural beliefs in addition to mainly using bronze (as a substitute of stone) for tools, in accordance with the British Museum. In the overall sense it’s the era of barrows or cremations, and folks living in roundhouses and clearing forests for his or her livestock — but dating and interpretation is difficult.
No one on the time called it the “Bronze Age” — that is a Nineteenth-century term. Furthermore, different regions of the world experienced the “age” in alternative ways and in numerous times. In what we now call the UK, the Bronze Age lasted from roughly 2,200 BCE to 800 BCE, British Museum officials stated — but even that dating has loose boundaries as local U.K. groups were highly distinct from one another.

The Bronze Age was a really very long time period — roughly 1,400 years within the U.K. by the museum’s reckoning. So what was generally true of a gaggle in the sooner a part of the era is likely to be very different by the tip. But archaeologists can use tools comparable to pottery, burial practices and scientific processes — like carbon dating, or measuring the decay of 1 style of carbon relative to a different — to review the Bronze Age.
It is vital to know all this to follow what archaeologists try to uncover at SaxaVord. What we now call Shetland does have Bronze Age finds, but not very many. Communities within the region were also highly distinct from each other. While each find at SaxaVord is precious, different areas of Shetland can have very alternative ways of living shaped by their environment, their local groups and by their neighbors.
On reflection, Turner said, it wasn’t an excessive amount of of a surprise to search out Bronze Age activity at SaxaVord. “The world of land is insular, and it’s got sea on either side under these big skies. It’s totally flat by way of a lot of the landscape. It looks like a great place for there to be prehistoric presence.”
The world shows no evidence of cultivation, Turner noted, so presently no person appears to have lived nearby. That said, future spaceport excavations may uncover more evidence. While an important deal of the SaxaVord area has been recorded, there still are other relatively untouched spots.
Turner said the Bronze Age in Shetland generally was marked by more rainfall than within the previous era, the Neolithic. Peat, a key source of fuel, was growing more intensively. However the colder and rainier climate encouraged communities to maneuver downhill searching for higher habitation areas.
“Life is getting that bit harder, but having said that in Shetland, loads of the homes and the best way they live doesn’t seem to alter terribly much,” Turner said. “You do see change seen within the sorts of burial and the sorts of pottery coming in … after which there’s something called burnt mounds, which are available at the tip of the Bronze Age. So you have got cultural changes happening, but slowly and over an extended time frame.”
Also within the broader Shetland region, evidence of Bronze Age trade is visible much further to the south. The variety of clay molds there appears to be Irish, suggesting some link across the Irish Sea, Turner said. And as copper and tin were each required to make bronze, tin imports got here in from the southwest of England late within the Bronze Age to hitch with locally mined copper.
Turner emphasized the SaxaVord exacations will help archaeologists gain insight concerning the Bronze Age not only there, but in Sheltand at large, particularly with regards to understanding its people. For instance: teeth evaluation of the burnt bones may show where people grew up, as local water is trapped within the bone during childhood.
“There’s an awful lot that we could learn because we all know so little,” Turner said of SaxaVord’s contribution. “Because the excavation goes on, it can begin to unfold a bit more of a story as to what is going on on there.”
