The ORCA Archaeology team are continuing work this week at the proposed SSEN Transmission sub-station in Finstown, Orkney. 

The area of the dig is continuing to grow as more of the archaeology is uncovered. Trenches excavated last week have been extended to make one large area, while test trenches have discovered extensive midden (rubbish) deposits up to a depth of 0.6 metres.

Meanwhile the cist and associated features unearthed two weeks ago is the subject of detailed excavation by one of the team. The possible Bronze Age cist itself appears to be empty with no obvious contents, but the material partly filling the stone box has been packaged for later analysis.

Intriguing archaeology is also beginning to emerge across the whole area, with two possible domestic prehistoric structures being excavated on one of the mound summits. The full extent of the structures has been exposed, showing large flags and a sunken central area. Hand excavation of the occupation deposits and identification of the internal stonework is underway and should shed some light on the age and use of this possible prehistoric settlement.
​
The team have also been investigating the thick midden layers around the north and east sides of the mound. Midden is in effect an ancient rubbish dump and usually holds great interest for archaeologists as they contain a treasure trove (sometimes literally!) of items and remains which can give the team an understanding of every-day life at the site. The midden material at this site is very complex and close to the structures, which means that this area was occupied for a considerable length of time. 

Even more interesting for the team was the discovery of pottery with Beaker-style decoration in one of the middens. The vessel was broken, but was recognisable as a style known in Orkney from other excavations and is always associated with domestic rather than funerary or ritual sites. These vessels date to the late Neolithic or Early Bronze Age across Orkney.
​
Other members of the team have completed hand-dug trenches across the low earth bank apparently overlying a cobbled surface that runs around the ridge in the boggy, peaty ‘valley’ between the mounds. There will be more information on this extensive cobbled area as the dig progresses. 

Further excavation has also revealed small stone heaps near the cist, with evidence of in situ burning under one of the stone heaps.  Working out what this means in terms of what was going on around the cist is just one of the puzzles confronting the team.

​The initial geophysical survey undertaken by ORCA Archaeology last year indicated that this site would contain extensive archaeological remains. The excavation phase of the investigation has more than confirmed this, and that the area contains possible archaeology dating back to the early Neolithic – the time of the first farmers in Orkney.

​
ORCA Archaeology were commissioned by Scottish and Southern Electricity Networks (SSEN) to commence archaeology excavation at the site of the proposed new sub-station at Finstown. 
​
Orkney is recognised to be at the forefront of the rapidly expanding renewable sector in the UK. The proposed Finstown Substation will form part of the multi-million pound Orkney Transmission Connection and Infrastructure project which aims to reinforce the electricity transmission connection between the renewable energy providers on the islands and the mainland of Scotland.

A team from ORCA Archaeology discovered a 3,500 year old burial cist last week while undertaking exploratory archaeological excavations on behalf of SSEN Transmission in Orkney. 

The cist was found intact at the proposed Finstown substation site, just below the ground surface, and consists of a stone-lined box capped with a large flat stone, and would probably have contained the remains of an individual who lived during the Bronze Age.

The burial was discovered by ORCA Archaeology as part of SSEN Transmission’s commitment to undertake environmental survey works ahead of construction, should the substation be approved. 

Local soil conditions aren’t great for the preservation of bone, and at first sight the cist appears empty, but careful excavation may reveal some traces. 
​
Standing around the cist in perhaps the same position as mourners did 3,500 years ago, the ORCA team discussed with SSEN Transmission the importance of the find and the next steps involved in excavation and recording, and the implications of the discovery for our understanding of how people lived and worked in the landscape.

Pete Higgins, Senior Project Manager ORCA Archaeology said, “Previous survey work told us there was significant archaeology present at the site and we are pleased that within the first few days we have our first major find.  It is fascinating to think that we are the first people in 3,500 years to look into this structure. We are working with SSEN Transmission to record the archaeology of the site, and this is a great start.”

​SSEN Transmission has submitted a planning application for the onshore substation near Finstown. The substation is a critical component of the proposed network reinforcement which is required to support renewable electricity generators across Orkney looking to connect to the main GB transmission system for the first time.  Its progress, as well as that of the reinforcement programme, remains subject to all planning and regulatory approvals.

SSEN Transmission’s Environmental Project Manager, Simon Hall continues,
“As a responsible network operator, we take our environmental standards very seriously and strive to do everything we can to ensure that our proposed works minimise disruption and impact to our host communities, whilst meeting our License obligations. For this particular project, that includes working with local archaeological experts ORCA as part of our pre-construction assessments to fully understand the archaeological features and history at the Finstown site. We are delighted that it has resulted in the discovery of such an exciting feature that otherwise may never have been found. We look forward to continuing to work closely with ORCA Archaeology as the excavation progresses.”

The planned archaeology work at the proposed substation site will involve a programme of excavation, which will investigate anomalies identified through earlier surveys conducted by ORCA Archaeology.

Magnetometer (geophysical) surveys revealed several areas of archaeological interest (Figure 1 below), which were subsequently investigated by trial trenching.  Interestingly the large anomaly shown at 8 in Figure 2 has been interpreted as a lightning strike rather than archaeology, but looks pretty spectacular in any event!
​
The sub-station site sits in an area of low glacial mounds laid to pasture, at the foot of Hill of Heddle.  An old road or track formerly ran through it along the present field boundary angling NE from Stymilders, which itself was the site of a 19th century school.  The field boundary is shown in Figure 2 below.

The trial trenching found extensive deposits of ‘midden’ - material containing debris from human occupation - and several stone structures, probably dating from the Bronze Age (about 2000BC to 800BC in Orkney) near Stymilders and the Neolithic (4000BC to c. 2000BC) in the eastern field, (feature 7 in Figure 2 above).

The current excavation follows on from this previous work and targets the known areas of archaeological potential.  The ORCA Archaeology team will open a series of large trenches as shown in Figure 3 below, take samples of the midden material, investigate and record the structures present. 

Pete Higgins, Senior Project Manager, ORCA Archaeology commented, “This is a rare opportunity to excavate a large area of good archaeological potential and we anticipate it will add significantly to our understanding of how people interacted with the landscape near the World Heritage Area.”

SSEN’s Environmental Project Manager, Simon Hall adds, “Given Orkney’s vast, rich and highly significant archaeology, we are fully committed to work with all relevant bodies to avoid or mitigate impacts and protect Orkney’s archaeological heritage.In the event of any archaeological discoveries of interest we are committed to ensure these are fully documented, preserved if possible, with our findings shared with interested parties.”

The ORCA team sometimes have to work in the harshest of conditions and in some of the most isolated areas of Britain. This means that the team has to rely on its own resources to get the job done, but on other occasions the sun shines and the rain and wind stays away.

Such were the conditions on the first few days of the geophysics survey at Kergord on Shetland, with clear blue skies and a few clouds that didn't threaten rain or hail or snow, and the geophysics survey was completed without resort to wet weather gear.

The project, commissioned by Balfour Beatty Construction Services UK, was  to undertake a scheme of archaeological fieldwork at Upper Kergord, Shetland, in advance of the development of a proposed electricity converter station.

The investigation focused on four excavation areas targeted over features identified through walkover survey, desk based assessment and during watching briefs of geotechnical works.

The excavation encountered features that represent elements of the Post Medieval/crofting period landscape, including a shieling-type shelter, as well as structural remains which potentially provide evidence for Neolithic or Bronze Age land management.

Work carries on as part of the A9 dualling as Archaeologists discover a possible Iron Age structure, pottery and a stone tool near the road. The finds have been made on the Crubenmore to Kincraig stretch of the route to be dualled.

The dualling of the A9 trunk road from Perth to Inverness is one of the largest infrastructure projects in Scotland. Over 80 miles of road will be improved over the next 8 years to improve the quality and reliability of journeys along the road. In common with all major infrastructure projects, Transport Scotland has appointed archaeologists in order to check for previously hidden ancient structures and other significant archaeology.
​
Commercial archaeologists, Orkney Research Centre for Archaeology (ORCA), have been working alongside design consultants CH2M Hill / Fairhurst Joint Venture, and ground investigation contractors, and have opened trial trenches to investigate several interesting anomalies identified in a geophysical survey.

The interest of the archaeologists was heightened further as the ground investigation works are located close to a prehistoric souterrain called Raitt’s Cave near Kingussie. This underground structure is a scheduled monument and is very large compared to most similar structures in Northern Scotland, and yet soutterains in general remain enigmatic as their use is still debated by archaeologists across the UK. They may have been used for storage, defence or some unidentified ritual, but commonly they are associated with settlement in the Bronze and Iron Ages.

Following discussions between Transport Scotland and the ORCA team on site, the preliminary work continued as the archaeologists investigated the anomalies. Traces of a previously unknown structure were quickly identified together with a scattering of pottery sherds and a possible stone Ard point – a stone worked into a point for use as part of a plough. The pottery was identified by Martin Carruthers (Iron Age specialist at the University of the Highlands and Islands Archaeology Institute) as a possible collection of early Iron Age sherds. These finds led the archaeologists to believe that the structure may be associated with the souterrain.
​
Following advice from ORCA, the team quickly formulated a plan to incorporate the archaeological investigation into the schedule, meaning that the important A9 infrastructure development work could continue while the significant archaeology was recorded in more detail. 

Keith Brown Cabinet Secretary for Economy, Jobs and Fair Work said: “Our work to dual the A9 will bring undoubted improvements for road users including improved journey times and significantly improving road safety. At the same time, the ongoing design work has opened a window into Scotland’s past. We have already been able to shed more light on the Battle of Killiecrankie and now these latest finds on another stretch of the route offer evidence for experts on how our prehistoric descendants lived in the Iron Age.”

​Peter Higgins, Senior Project Manager ORCA, commented, “We are tremendously excited by these finds in this archaeologically significant location. We are also pleased that we can work with Transport Scotland to make sure that these finds are recorded correctly without impeding the roadworks so vital to this Scotland’s economic development.”

Transport Scotland: The A9 dualling project is a £3 billion infrastructure project designed to improve the links between Perth and Inverness. 

The archaeological work on the hospital site was successful in identifying where the archaeology was located and informing the strategy to avoid it.

An archaeological watching brief was undertaken on behalf of NHS Orkney, during the topsoil strip by machine, across the site of the new hospital and healthcare facilities in Kirkwall from the 24/04/2017 - 1/05/2017.
