Barrow-Loads of Barrows: Excavating a Monumental Pictish Cemetery at Tarradale on the Black Isle

In the first three weeks of September 2019 volunteers from the North of Scotland Archaeological Society supported by members of the local community excavated a suspected Pictish cemetery in a field near Tarradale House. Aerial photographs had previously shown the possible existence of a number of barrow graves in the area but there was little to see on the surface as the mounds had been almost totally ploughed away but their surrounding ditches appeared as ghostly outlines on the aerial photographs. A small, but growing, number of barrow cemeteries has been identified in Scotland but only a few excavated. Aerial photographs show the remains of at least 28 square and round barrows at Tarradale making it currently the second largest burial ground of this type in Scotland. The site could originally have been more extensive as parts of it have either been ploughed out or are too deeply buried to show in aerial photographs. Recent high-resolution photographs taken by drone have suggested the existence of more barrows towards the perimeter of the field and possibly into an adjacent field. Our excavations showed that Tarradale was a barrow cemetery of monumental proportions and potentially one of the most important in Scotland.

Although we are still waiting for radiocarbon dates from the Tarradale excavation, the presence of round and square barrows and their spacing and distribution leaves little doubt that we are dealing with a Pictish cemetery potentially from the 5th or 6th century AD, an important period in the formation of early kingdoms in northern Britain. Tarradale lies in the eastern side of Ross-shire on the Beauly Firth and only six miles from Craig Phadrig, an important stronghold and regional capital in the Kingdom of Fortriu. Part of this centralisation of power was reflected in the creation of monumental cemeteries and Tarradale may have been the burial place of the local elite. No Pictish symbol stones have been found at Tarradale, although symbol stones, including cross slabs with symbols on them have been found in adjacent parishes, the nearest being the recently discovered Conan stone three miles from Tarradale. However, in the same field as the barrow cemetery, a fortified settlement was excavated in the 1990’s; no primary dating evidence for the Picts was obtained but on stylistic grounds pottery from the fortified site has been dated to between AD 300-800 so this may well be the settlement focus of some of the people buried nearby.

Buntait, Glenurquhart: A Bronze Age Landscape?

by James McComas (NOSAS)

The larger barrow at Buntait – feature ‘X’ on the map below.

Although I have lived in Glen Urquhart for some years, it was only comparatively recently that I first visited Buntait, a hamlet just to the north of the Clava type chambered cairn at Corrimony. This was despite me hearing from a number of local people about the amount of upstanding archaeology that was there. I think I must have presumed that because there are no scheduled monuments there it could not be that interesting – an assumption I will not be making in the future. Later research confirmed that Buntait is in fact full of prehistoric (and post medieval) features – including hut circles, field systems, burnt mounds and rock art. Not only are the field systems extensive and some of the hut circles very well preserved, but also there are a couple of ditched barrow features. Locally, only Garbeg is comparable in terms of prehistoric remains.

Consequently Buntait became the subject of three archaeological field trips in 2017; two led by NOSAS, and one as part of the Archaeology Scotland Summer School planned with the assistance of NOSAS. There were also numerous smaller sorties for quadcopter flying, polecam photogrammetry, rock art recording (for SCRAP) and general investigation.

“The Glenurqhuart Story” by Alistair Mackell published in 1982, provides a useful if perhaps now outdated introduction:

Not far from the Corrimony Burial Cairn, on Buntait lands, was a settlement of some considerable size where clearly marked hut circles and cairns suggest a community practising primitive agriculture and a boundary wall, which can still be traced, may have served to protect domestic animals from prowling wolves or other marauding wild animals. Some of these circles are 30 feet in diameter and in the centre of at least one, is a depression which may have been a fireplace. These circles are low banks of stones covered with grass or heather about 2 feet high and 4 feet wide at the base. It is difficult to imagine one large roof covering such an expanse, but if so, it would probably have been formed of wattles and thatched with heather or turf, giving, when complete, a dome – shaped appearance. In each case there is a break in the circle at the south east which indicates the entrance. In other parts of Scotland where these structures have been carefully examined, hearth paving stones have been discovered, but we are unable to reconstruct much of the everyday life of the people of these long bygone days, and we can merely conjecture that they combined hunting with their primitive agriculture, for the Highlands were rich in wildlife.

The Picts at Garbeg and Whitebridge

by James McComas (NOSAS)

The Pictish people of the mid to late first millenium AD once inhabited what is now northern and eastern Scotland. They left very little written record and the evidence of buildings so far identified are sparse. Perhaps their most obvious remains in the landscape are the enigmatic symbol stones and the imprints of their burial sites.

Although modern Angus and Perthshire have traditionally been seen as the Pictish heartland, in recent years new research is reveavaluating the importance of the northern picts, north of the Mounth. Two highland burial sites which feature impressive upstanding remains are to be found on opposite sides of Loch Ness; at Garbeg near Drumnadrochit, and at Whitebridge in Stratherrick. Pictish funerary practices appear to have been diverse (see our earlier blog post), however barrow* cemeteries have been identified as one recognisable form. Round and square type ditched barrows appear alongside each other at both Garbeg and Whitebridge – a feature thought to be unique to the Pictish cemetery.

(The brown patches on the photo are the result of recent gorse clearance, and dark green areas are piles of cut vegetation.) The barrows excavated by Wedderburn and Grime on this plan are nos 1,2,3 and 8.

Garbeg and Whitebridge were visited by NOSAS field trips in 2014/ 2015 and Garbeg has also been the subject of gorse clearance, quadcopter photography (blog post section 4) and QGIS survey by the group. Subsequently in 2015 many NOSAS members were involved with survey and excavation by the University of Aberdeen’s Northern Picts Project on possibly contemporaneous building remains at Garbeg.

The cemetery at Garbeg (Canmore ID 12281, HER MHG3361) consists of 23 square and round barrows with surrounding ditches. The barrows are thought to cover single long cist burials. They are situated on a natural plateau at an altitude of some 300m on open moorland used for rough grazing.  The immediately surrounding landscape is one rich in archaeological remains, including prehistoric field systems, groups of hut circles and a series of burnt mounds which are largely thought to predate the Pictish period.

The Church of the Immaculate Conception, Whitebridge

by Marion Ruscoe (NOSAS)

During a recent NOSAS field trip to archaeological sites on the east of Loch Ness, our attention was drawn to the Roman Catholic Chapel near Whitebridge (NH 49496 17045 – HER ID MHG47419) which is situated close to the Pictish Cemetery there (see separate Blog Post). The architectural style is deceptively simple, suggesting an earlier building date than was actually the case, and perhaps also reflecting a continuity with the croft buildings which must have preceded it. The following is the result of my research into the history of the site and its architecture.

By the middle of the 19th Century there was perceived a need for a chapel to serve the small number of Roman Catholics who lived in Stratherrick.  Lord Lovat offered a site for this purpose at the croft at Bridge of Loin and a collection, which raised £49, was undertaken to pay for the new building.  Alexander McDonell, a native of Fort Augustus, who had recently returned to Scotland from Australia, contributed a further £391 and in March 1859 there was a call for estimates from masons, carpenters, slaters, plasterers and plumbers for work on the new Roman Catholic Chapel and Clergyman’s House to be built at Dalcraig (Dalcrag) in Stratherrick. The chapel, seating 130, was consecrated in December 1859 and dedicated to the Immaculate Conception.

At a time when other denominations in Stratherrick were building substantial churches in a traditional style and in prominent positions, the Roman Catholic church at Whitebridge is simple, rather modest and set back from the road, so that it is not immediately obvious to passing traffic.  It is a single storey building which resembles a croft house.  The door is in the west gable and only the lancet windows betray its religious purpose.   At the east end there appears to be domestic quarters and this may have been the original clergyman’s house which was superseded by a more substantial dwelling house at a later date.  In A Country called Stratherrick Alan Lawson suggests that this larger house was built around 1900.  However, although the two buildings are very different in style, the 1st edition 6” OS map shows the footprint of a building which is very like the present one in its entirety so it’s more likely that they were designed and built together.

Experiments using a Quadcopter for Archaeological Aerial Photography

by Alan Thompson (NOSAS)

Introduction

I’ve had my Quadcopter for over a year now, had great fun flying it, and have produced many interesting images.  I recently showed a selection of images at a NOSAS evening, and was asked if I would write this blog and share some of the things I’ve learned along the way.

Of course the pictures are what it’s all about and even if you’re not interested in my comments, I hope you enjoy looking at them.

Background

Inspired by some of the wonderful aerial photos (APs) I’ve seen (for example on Canmore) I have long thought how good it would be to be able to take such pictures of our own archaeological sites.

For several years I have been interested in photogrammetry and experimented with that, especially of rock art where the production of a 3D surface and use of computer generated lighting and shadows can give some great effects.

In 2013 I began to investigate kite aerial photography (KAP) but the possibility of using a Quadcopter also emerged and I realised that technology and prices were moving so quickly that it might be a better option.  In early 2014 I decided that the only way to learn was to buy one.

The Quadcopter – getting ready to fly

Most amateur Quadcopters are sold with very wide angle cameras, with the intention of video recording, and also providing a pilot’s view (called first person view or FPV).  This is less than satisfactory for archaeological aerial photography, and so I bought a Quadcopter without a camera, with a view to fitting my own.

The camera is obviously critical, and it needed to be light (ideally <300g including battery), robust, of good enough quality, and with an interval timer.  Unfortunately I could find no such camera.  All those with interval timers are heavier, for example those used for kite aerial photography.  A solution can however be found in that a group of people spend their time hacking the software of Canon cameras (google CHDK) and provide a hacked version for some models which enables an interval timer to be run.

Having bought and hacked my camera and got the interval timer working I had to fit it to the Quadcopter.  The main problem is the high frequency vibration from the rotors which renders the pictures useless.  A suitable anti-vibration mounting was needed, all within the weight limit.

Next, to prepare for the first test flight.  The web (YouTube) is full of videos of alarming crashes and fly-aways.  The Quadcopter instructions are daunting saying that a first flight should be from the middle of a large field, with no wind and no people about.  There is also the matter of insurance (it could certainly hurt someone badly), and the possible need for a CAA licence.  The regulations here are changing quickly but at present as a hobby flier I can insure through the British Model Flying Association (BMFA), and (unlike a professional archaeologist) have no need of a CAA licence provided I fly within line of sight, avoid certain areas (eg near airports) and limit the height.  I would again emphasise that this is all very much in the news and changing and my observations here will quickly be out of date.

The first flight is bit nerve-racking, but set to auto mode the Quadcopter uses its own GPS and compass and is set so that (more or less) if you let go of the controls it just hovers where it is.  Flying in this mode is reasonably straightforward.  I have not dared try any of the advanced modes as yet.

Pictish Burial Practices and Remains

by Roland Spencer-Jones (NOSAS)

These notes are in preparation for NOSAS field trips to two recognised Pictish cemeteries in the Highland region –

• Garbeg near Drumnadrochit on Saturday 1^st November 2014. See Highland Council HER, RCAHMS Canmore
• Whitebridge near Foyers on Sunday March 8^th 2015. See HER, RCAHMS Canmore

(See also separate post about Garbeg and Whitebridge cemeteries).

The Picts, those most elusive of early medieval Scottish peoples, seem to have disposed of their dead in a variety of ways. Remains that can still be found in the landscape include cremations, simple burials in the ground, long cist burials, burials under cairns, and burials under round and square barrows. It is also probably true that disposal was achieved by exposure and excarnation – practices continuing from pre-history. What remains unclear is how any of these contemporaneous burial practices were chosen for a specific individual or group.
