Exploratory dig confirms existence of Brodgar Neolithic complex

Centuries-old conceptions about the Ness of Brodgar – the thin strip of land between the Harray and Stenness lochs – look set to be turned on their heads following a series of exploratory excavations on the south-west of the ness.

Last year’s discovery of a structure, half-way between the Ring of Brodgar and the Standing Stones of Stenness, gave the first hint that ideas were going to have to change.

A domestic settlement in an area thought to be solely the domain of ritualistic and funerary monuments was a clear sign that certain long-held notions about the Brodgar peninsula needed to be looked at again.

The structure’s discovery, together with a series of extensive geophysics scans of the World Heritage Site area, was beginning to indicate the scale of prehistoric human activity on the Ness of Brodgar – and perhaps, most intriguingly, that this activity wasn’t entirely based around the ceremonial rings.

But even the geophysics results couldn’t prepare the archaeologists for what they found after digging a number of small exploratory trenches around the site of the “Brodgar New Hoose” – in particular that the area around Lochview could be still house an extremely well-preserved Neolithic village.

A team of four archaeologists, led by Nick Card, projects manager for the Orkney Archaeological Trust, has spent two weeks on the site and uncovered tantalising evidence of a massive complex of structures that once stood between the two stone circles – an area of approximately 2.5 hectares that appears to have been used throughout the Neolithic period (approximately 3500-1800 BC).

These dates mean that the earliest phases of the settlement were standing long before the construction of the Ring of Brodgar, and are perhaps contemporary with the Standing Stones of Stenness.

Nick Card explained: “We knew this area was covered in magnetic anomalies from the scans that were carried out previously, so for this project we deliberately chose to put down trenches that would avoid the major items of archaeology indicated by the geophysics.

“But even in these ‘quiet’ areas we’ve been astounded as every one of the five trenches has produced archaeological remains. We really are at the heart of Neolithic Orkney here.”

Landscape alteration

What has become clearly apparent is the way the landscape was altered by these Neolithic settlers.

The trenches revealed massive quantities of deliberately “improved” soil over the area of the settlement – soil enriched by the addition of midden material to a maximum depth of 2.5 metres.

This human alteration to the landscape has resulted in a massive man-made mound on which the current house, Lochview, now stands.

Standing on this man-made, field-spanning mound, the profile of the Ring of Brodgar and its surrounding howes juts starkly from the horizon to the north-west.

At the bottom of a deep trench, on what would appear to be the periphery of the settlement, were what appeared to be the lower courses of an early Neolithic structure.

A short distance away, a few centimetres beneath the top soil and higher up the mound, lies the late Neolithic structure discovered by Beverly Ballin-Smith last year.

This confirms that as time passed, and as earlier structures fell out of use, new buildings were erected on top – a process that led to the gradual formation of the current settlement mound.

But even looking at the remains of the oldest building, Nick suspected there were still earlier levels underneath.

“We think there’s even earlier soils under this, so what we’re looking at is a constant change in the height of the mound with the result that the landscape was being altered throughout the life of the settlement.”

Almost guiltily referring to that oft-used phrase – “scratch Orkney’s soil and it bleeds archaeology” – Nick admitted that on this site it couldn’t be truer.

“What we have come to realise is that we’re looking at a landscape dotted with more archaeological remains and sites than even the geophysics scans have picked up,” he said.

A chambered cairn?

Towards the western outskirts of the settlement, and overlooking the water of the Stenness Loch, is a large geophysics anomaly that may be a chambered cairn.

Although it will take a full excavation to confirm whether this is the case, if it turns out to be a cairn – and is contemporary with the settlement – it provides another interesting challenge to current thinking on the role and positioning of these “houses of the dead”.

So far these tombs have generally been found outside areas of domestic settlements – in locations that led to the idea that they were deliberately kept away from and distinct from everyday life.

If the anomaly at Lochview proves to be a tomb, the archaeologists will have to look at this idea again and it may provide some clues as to the structures’ roles other than as a simple repository for the Neolithic dead.

Moving to the north-west and closer to Brodgar farmhouse, another trench contained a rectangular stone setting that looked remarkably like a burial cist The mystery deepened, however, when it was found to contain no burial remains.

Although the brief glimpse of the structure was intriguing, it will have to remain a mystery until further excavation can confirm whether it is an isolated feature or part of a larger building, the purpose of which is unclear.

One of the most striking features on the geophysics results was a huge rectangular anomaly that roughly follows the modern road for approximately ten metres before bending westward at a sharp 90-degree angle.

The scale of this “wall” led to its interpretation as a medieval construction, so a trench was put down to explore it further.

The long, thin trench showed extensive areas of stonework, with what appeared to be a large paved area towards the centre of the settlement.

Nick Card explained: “All we can say for sure about this is that we now know it is definitely not medieval. All the finds have been prehistoric. It’s really impossible to say for certain from what we’ve seen so far but it seems to be a new class of Neolithic monument, for Orkney at least.”

He added: “It could be something to define the boundaries of the settlement area, or perhaps in some way related to the cursus monuments (elongated rectilinear earthwork enclosures) found in the south. To make any sense of it is going to require a much bigger trench and as to what it is and was used for awaits a full excavation.”

With the dig drawing to a close, Nick pointed out some of the other areas of the site that their investigations had not even touched – including the site of a large stone structure similar to Structure Eight at the nearby Barnhouse Settlement, and a large mound by the road that might even house broch remains.

Summarising, Nick said: “We’ve managed to fulfil all our main objectives and shed a little more light on this section of the World Heritage Site. But as usual we’re left with more questions than answers. This has simply been a quick look at the site and we can’t fully understand a lot of what we’ve found, but it shows the potential of this area for future work.

“What has become clear is that a full excavation would be dealing with very well preserved Neolithic structures. Compared to the Barnhouse Settlement which was very badly degraded when excavated, the buildings in this settlement have perhaps survived to up to half a metre tall.

“There is no doubt at all that further work on this site will help us further understand the Neolithic in Orkney, in particular the Ness of Brodgar’s role in the daily life, rituals and beliefs of the Neolithic inhabitants of the county.”
