The Ring of Brodgar

“[In Stenness] beside the lake are stones high and broad, in height equal to a spear, and in an equal circle of half a mile.”

The Ness of Brodgar and monuments.

With a diameter of 103.6m (340ft), the Ring of Brodgar is the larger of the two stone circles in the Heart of Neolithic Orkney World Heritage Site and one of the biggest in the British Isles.

In contrast to the giant megaliths of the Stones of Stenness, Brodgar’s are smaller, varying in height from 2.1 metres (7ft) to a maximum of 4.7 metres (15ft 3in).

Although only 27 remain, it had long been proposed – based on the spacing of the surviving megaliths – the circle once contained 60. Then, in 2008, a geophysical survey suggested there might have been more.

The tomographic survey focused on the south-eastern half of the ring and suggested there were an additional 19 socket holes. Including the surviving stones and stumps, this meant 36 stones once stood in that section.

Assuming the same applies to the other half, the Ring of Brodgar could have contained more than 70 megaliths, but – and this is an important point – not necessarily at the same time.

Enclosed by a rock-cut ditch, access to the interior of the stone circle is by two opposing causeways. The south-eastern entrance is just over a metre wide (3.3ft), narrow compared to the 3.4-metre-wide (11.15ft) north-western causeway.

We do not have secure dates for the ring – the interior has not been excavated – but it is generally thought to be later than the Stones of Stenness, a mile to the south-east, and date from between 3000BC and 2500BC.

Dates from the ditch, however, suggests it was dug between 2600BC and 2400BC. But, like Maeshowe, we cannot assume the ditch and the stone circle were contemporary.

Was the ditch dug first or at the same time stones were being erected? Or was it a much later addition? Perhaps to enclose the site after the significance of the ring waned?

A ring of stones

“Could the circle be a place where, over considerable time, many different groups brought stones, with each completing sections or adding to those of others?”
Colin Richards. Rethinking the great stone circles of north-west Britain (2004).

In light of the discoveries at the Ness of Brodgar complex, the long-held notion that a single, elite individual or group was responsible for the construction of the Ring of Brodgar has to be questioned.

Just as we suspect the Ness was a meeting place – a location where people gathered from all over Orkney and perhaps beyond, the same may be true for the ring. And just as the Ness site was an ever-changing, evolving site for centuries, we should perhaps stop looking at the stone circle as the result of a single construction event.

Constant change

“The raising of each slab brings different people into the story of the circle, people who live and pass and fade from the memory of those dragging stones in their wake.”
Mark Edmonds. Orcadia (2019).

Ring of Brodgar. Sigurd Towrie

There is a tendency to look at sites such as the Ring of Brodgar and Stones of Stenness and regard them as “completed” monuments. Someone in the Neolithic decided to erect a stone circle and set a plan in motion to create a finished, final product.

But it has been argued that there was no end goal — no finished monument to work towards and no timescale.

Instead, the erection of stones at the Ring of Brodgar took place over generations with the composition and appearance of the stone circle constantly changing as megaliths collapsed, were added, removed or replaced. Because it was a constantly changing monument, and never meant to be complete, in the Neolithic it may have looked much the same as it does today – single, paired and clusters of megaliths separated by gaps of varying sizes [2].

To the team who excavated at the ring in 2008, it was not the completed stone circle that was significant to its builders but the physical act of its creation [2].

The goal, they suggested, was not a completed monument. Instead, the prestige of quarrying, transporting and erecting a fine megalith was the driving force behind the development of the Ring of Brodgar.

Geological examination of the Brodgar stones confirmed they came from at least seven different quarries and were transported to the site from across Orkney [2]. Did these different quarries, and the stone obtained from them, represent different Orcadian communities?

The fact the different rock types in the ring were clustered together [2] certainly suggests so, with different sections of the stone circle perhaps relating to the different social groups who came together to erect the ring of stones.

Professor Colin Richards has suggested these communities – although they worked together – were fiercely competitive and the Ring of Brodgar was an arena where they attempted to outdo each other with visible shows of prestige and power.

A far cry from the harmonious Neolithic “temple” the ring is often proclaimed as today.

Built to endure?

The toppling of monoliths and the ‘breaking’ of the circle also seems to have been varied in character; some stones were intentionally removed, whilst others were apparently snapped off and left as stumps in the ground.”

The 2008 excavation at the ring also revealed something surprising – the socket holes for the Brodgar stones were incredibly shallow. Two were excavated and measured a mere 27cm (10.6in) and 18cm (7in) deep [2]. Compare that to those encountered at the Stones of Stenness, which were between 90cm (2.95ft) and 1.3m (4.27ft) deep [3].

Clearly, despite the effort put into quarrying and transporting the megaliths, they were not erected to endure. As Prof Mark Edmonds put it: “… the emphasis for the builders was on the moment rather than posterity.” [4]

Instead of permanence, it seems that appearance, and the illusion of grandeur, was paramount. Evidence of this came from tomography scans in 2008 that showed the megaliths at the causeways were broader and erected closer together, creating the illusion of a massive stone circle to those approaching the entrances.

We can see something similar in the structures at the Ness of Brodgar, where appearance seems to have been more important than structural stability.

At the ring, was the erection of a stone temporary? To be replaced or removed at a later date? Were they put up and left to decay and collapse? We cannot say. What is clear, from the current evidence, is that the builders were not concerned about permanence.

We cannot say for sure why the site for the Ring of Brodgar was chosen, but it seems very likely that it was considered significant – perhaps for a number of reasons.

There were undoubtedly better places to erect a stone circle — more visually prominent sites, for example, that did not require the builders to mine through bedrock. But as we will see, perhaps the easy option was not the best option.

We have discussed elsewhere that the ring may have monumentalised and enclosed an earlier pathway along the Ness of Brodgar. The fact the stone circle has two opposed access causeways certainly suggests that movement through the monument, and along the Ness, was an important element.

The ditch

Like the Stones of Stenness, the Ring of Brodgar is classed as a henge monument – despite the fact it has no outer bank and, going on current evidence, probably never did.

What it does have is a massive encircling ditch.

Cut from solid rock using nothing but antler picks, stone tools and sheer effort, the 123-metre diameter ditch surrounding the circle of stone, was originally over four metres deep (13ft) and ten metres wide (32ft) at ground level [2].

An estimated 4,700 cubic metres (11,000 tonnes) of rock had to be quarried to create the 386-metre-circumference ditch — a task estimated to have taken 80,000 hours [5].

Two sections of the ditch were excavated in 2008 and revealed the sheer scale of the undertaking. It was deep, broad and flat bottomed and was not dug in one continuous process.

Instead, it was clear that the ditch had been dug in segments – perhaps over many years and involving different groups of people [2]. Were the people who brought in the stones responsible for digging their own segment of the ditch?

As always with ditched monuments there is the question of where the ditch sits in the biography of the site. Were the megaliths erected before or after the ditch was cut?

Over the years, the assumption was that the standing stones must have been first, and the ditch dug around them. The reason? Efficiency — it would be easier to move the stones into position before a massive ditch was dug.

The danger here, however, is assuming that the Neolithic people wanted to make things easy. The modern mindset is focused on speed and economy of effort – what is the easiest and quickest way of getting a job done?

If it was the construction of the stone circle, rather than a completed monument, that was important, it could be that the harder the task the more significant the action.

When it came to the ditch, there is no doubt its creation was a monumental task.

That said, dates from the 2008 excavation suggest the Ring of Brodgar ditch was dug between c2600-2400BC, and shortly afterwards began to quickly silt up [2].

This suggests the monument had gone out of use and fits with the idea of the ditch being a final addition, perhaps enclosing and sealing off the site.

It is interesting to note that the ditch around Maeshowe was dated to around 2700BC.

Quarrying the stones

Numerous published accounts of the Ring of Brodgar have claimed that some of the Brodgar megaliths were quarried from the surrounding ditch.

Excavation has showed this could not have been the case – the geology of the rock means that a complete megalith could not have been extracted from the ditch without breaking [6].

So, if they did not come from the ditch, where were they from?

We have seen that the geology of the surviving stones shows they came from at least seven different quarry sites. This corroborates centuries-old local beliefs that several quarries were the source of the stone circle megaliths.

One of these “traditional” sites is Vestrafiold, a hill in the neighbouring parish of Sandwick, overlooking the Bay of Skaill and Skara Brae. For millennia Vestrafiold was the site of quarried, but abandoned, standing stones [6].

Excavation between 2001 and 2003 not only confirmed that megaliths were being extracted from outcrops on the hill but provided an unparalleled insight into the Neolithic quarrying process [6].

Among the conclusions drawn from the fieldwork was that specific quarries were exploited for megaliths – perhaps places imbued with a special significance or role in the cosmology of the local communities [7].

Early accounts

The Brodgar ring was first recorded in the early 16th century, by the enigmatic author Jo Ben.

His 1592 Descriptio Insularum Orchadiarum, the oldest surviving account of the Orkney after their transfer to Scotland in 1468, makes no mention of the number of stones.

In 1792, the ring contained 16 standing stones, with eight lying prone [8]. By 1848, only 13 remained standing, ten lay “nearly perfect, but prostate” along with the “stumps or fragments of thirteen more” [9].

The Ring of Brodgar was taken into state care in 1906 and, two years later, most of the fallen stones were placed in what was thought to be their original sockets.

Since then two stones have suffered lightning strikes, leaving 27 standing today.

‘The temple of the sun’

Until the middle of the 19th century, the Brodgar ring was lumped in with the rest of the area’s megaliths and all known collectively — to antiquarians and mapmakers at least — as the “Standing Stones of Stenness”.

It was in 1851 that the name “Ring of Brogar” is first recorded.

Seeking to differentiate between the two stone circles, Lieutenant F.W.L. Thomas [9] dubbed the “lesser stone circle” of Stenness, “for the sake of distinction”, the “Ring of Stenness”, while referring to the “Great Stenness circle” as the “Ring of Brogar” [10].

Brodgar (Brogar) comes from the name of the nearby farm, which is Old Norse brúar – bridge and garðr – farm. In the same year, Daniel Wilson referred to “Great circle, or Ring of Broidgar (sic), as it is most commonly styled.” [8]

It seems likely these two chroniclers were using the name for the stone circle used locally, particularly because the majority of accounts before (and even afterwards) repeated the antiquarian’s favourite – the “Temple of the Sun”.

This title, and the “Temple of the Moon” for the Stones of Stenness, can be traced back to Martin Martin’s late 17th century account in which both stone circles are described as temples and states:

“Several of the inhabitants have a tradition that the sun was worshipped in the larger, and the moon in the lesser circle.” [11]

Reproduction of a 1784 woodcut by Dr Robert Henry, showing the “temple of the sun” marked F. This version was published in Hibbert in 1823.

One wonders who these “several inhabitants” were and whether they, or Martin himself, were influenced by the ideas of “druidic temples” that were beginning to drift up from the south [13].

As Wilson put it in 1851:

“The convenient terms of Druid altars and temples have long supplied a ready resource for the absence of all knowledge of their origin or use.”

The sun and moon temple titles, that had become firmly entrenched in the literature by the middle of the 19th century, prompted Wilson to declare that there was no doubt these “frequently designated” designations were “quite modem and spurious” [8].

Elements of Martin’s account are remarkably similar to Rev James Wallace’s 1693 A Description of the Isles of Orkney. Wallace, however, actually lived in Orkney and did not assign them the temple label. Nor did he mention of any tradition of sun or moon worship.

An interesting reference was made by the folklorist and historian George Marwick in the later 19th century. Marwick, a resident of the parish of Sandwick, lived a few miles from the Ring of Brodgar, proclaimed there was an old, and all but forgotten, name for the stone circle – Howastedgarth [14].

We will consider that next time.
