The origin of the giant sarsen stones at Stonehenge has finally been discovered with the help of a missing piece of the site which was returned after 60 years.

Last year archaeologists pinpointed the origin of many of the ancient monument’s massive stones. A new study identifies the source of the rest. A test of the metre-long core was matched with a geochemical study of the standing megaliths.

The 23ft sarsens each weigh around 20 tonnes

Archaeologists pinpointed the source of the stones to an area 15 miles (25km) north of the site near Marlborough.

English Heritage’s Susan Greaney said the discovery was “a real thrill”.

The seven-metre tall sarsens, which weigh about 20 tonnes, form all fifteen stones of Stonehenge’s central horseshoe, the uprights and lintels of the outer circle, as well as outlying stones.

The monument’s smaller bluestones have been traced to the Preseli Hills in Wales, but the sarsens had been impossible to identify until now.

The return of the core, which was removed during archaeological excavations in 1958, enabled archaeologists to analyse its chemical composition.

No-one knew where it was until Robert Phillips, 89, who was involved in those works, decided to return part of it last year.

Researchers first carried out x-ray fluorescence testing of all the remaining sarsens at Stonehenge which revealed most shared a similar chemistry and came from the same area.

They then analysed sarsen outcrops from Norfolk to Devon and compared their chemical composition with the chemistry of a piece of the returned core.

English Heritage said the opportunity to do a destructive test on the core proved “decisive”, as it showed its composition matched the chemistry of sarsens at West Woods, just south of Marlborough.

Prof David Nash from Brighton University, who led the study, said: “It has been really exciting to harness 21st century science to understand the Neolithic past, and finally answer a question that archaeologists have been debating for centuries.

‘Substantial stones’

“Each outcrop was found to have a different geochemical signature, but it was the chance to test the returned core that enabled us to determine the source area for the Stonehenge sarsens.”

Ms Greaney said: “To be able to pinpoint the area that Stonehenge’s builders used to source their materials around 2,500 BC is a real thrill.

“While we had our suspicions that Stonehenge’s sarsens came from the Marlborough Downs, we didn’t know for sure, and with areas of sarsens across Wiltshire, the stones could have come from anywhere.

“They wanted the biggest, most substantial stones they could find and it made sense to get them from as nearby as possible.”

Ms Greaney added the evidence highlights “just how carefully considered and deliberate the building of this phase of Stonehenge was”.

Stone Circle (“Special”) Access

20 08 2017

Before 1978 you were free to walk around inside the stone circle at Stonehenge once you’d paid your admission fee. The lack of any guards overnight meant people also hopped the fence once the site had closed.

Stonehenge at dawn.  A special access ‘inner circle’ visit at sunrise.

Finally, in response to the over 800,000 annual visitors, access was restricted. An article entitled “Heritage Under Siege” in New Scientist (Sept 27th, 1979) reports the Chief Inspector of Ancient Monuments and Historic Buildings as saying:

“The whole problem of Stonehenge is numbers … all through the year. What menaces Stonehenge are the millions of feet (and hands) of the ordinary visitors.”

… and continues:

“An archaeologist calculated that if each visitor walked around the central area just twice during his or her visit, the effect would be the same as having one man standing on each square foot inside the ring and jumping up and down on that spot 62 times every day throughout the year.”

After March 1978, everyone was banned from inside the circle – including archaeologists and other researchers, much to their annoyance. Department of the Environment officials said that the plans to allow out-of-hours access to “those with a special interest” had to be abandoned because the custodians were unwilling to work overtime. And so it remained for a long time.

Eventually things changed and these days it’s possible to book to go inside the stone circle on what is called a “Stone Circle Access” or “Special Access” visit. These are one-hour long slots before and after the monument is open to the public during the day, and a maximum of 30 people are allowed inside at a time.

You can book as an individual, or via a tour company who may (or may not) provide a well-informed guide to show you some of the hidden features that you might otherwise miss.

Once inside, if the light’s right you can pick out some of the hundreds of examples of wrencarved initials and names on the stones. One of them might even be that of Christopher Wren – a local lad who made good and went on to design the new St. Paul’s Cathedral after the Great Fire of London in 1666.

One thing that a lot of people fail to notice is the sound of the place – there’s a definite sense of entering into an enclosed, peaceful space a soon as you come in through the primary entrance beneath the central lintel of the three on the northeast side of the circle.

It’s only when you’re up really close to the monument that the epic scale of the stones really strikes you – the tallest one is over 7m from grass to top, and there’s a further 2.5m in the ground. Weighing in at over 40 tons it’s a beautifully shaped monolith that was part of the tallest trilithon on the site. Sadly its partner upright fell and broke long ago, leaving the lintel they both supported lying on its side in the southwest part of the central area.

The bluestones, though much smaller than the sarsens, are still impressive rocks – the tallest one stands leaning in front of the highest sarsen stone and has a wide groove worked all the way down one edge. No-one knows why.

There are a few rules – no standing on the stones, no touching them, no smoking – but apart from that you’re free to wander around and properly appreciate both the enormity of the large sarsen blocks, the elegance of the bluestone pillars and the ingenuity of the builders who created the monument over 4,500 years ago.

If you have the chance, by far the best way to see Stonehenge is through a Stone Circle Access visit.  

Stonehenge Guided Tours pioneered these Stonehenge access tours and offer frequent scheduled coach tours at sunrise and sunset. They can often arrange private custom inner circle tours with expert guides.  The Stonehenge Travel Company are based in nearby Salisbury and are considered the local Stonehenge experts.
