Greater Glasgow’s medieval origins revealed in Gallowgate Dig

Share this page

Archaeological remains of Glasgow’s earliest suburbs have been discovered by GUARD Archaeology. Several lines of well-preserved wooden posts with woven fencing, as well as pottery at a site in the Gallowgate area.

The discovery was made 4.5 metres below the current street level at the Spoutmouth area, which is being developed into social housing.

This is a remarkable survival of organic archaeology in an area of the city that has witnessed substantial development over the many years since Glasgow was first established. A small sliver of medieval Glasgow that has somehow survived centuries of building and rebuilding.

The site lay dormant as a car park until Wheatley Group developed plans to build 34 homes for social rent and two commercial units. The £9.295 million development is supported by a Scottish Government Grant of £5.57 million. As part of the planning conditions, a comprehensive archaeological investigation was required due to the site’s location on the edge of medieval Glasgow.

Aside from the foundations of 18th and 19th century buildings, nothing of great significance was apparent during the initial investigations, until the tops of wooden posts were spotted piercing through clays 4.5m down.

The Spoutmouth site lies on the south side of the former line of the Molendinar Burn which was once one of the most well-known water courses in Glasgow that drains into the River Clyde; it now flows underground having been culverted in the 1800s.

But going back in time, it has associations with St Mungo who founded his church on its banks in the late 6th century AD. By the 12th century the newly established bishopric and its cathedral were built not far from here at the top of the High Street. In AD 1175, King William the Lion conveyed Glasgow with burgh status. Burghs had been introduced by William’s grandfather David I and allowed Glasgow economic and legal privileges in return for significant tax contributions to the Royal Exchequers of Scotland.

The GUARD Archaeology team unearthed 63 upright posts arranged in three lines defining three broad linear areas. As these are so deep, the site is constant flooding from water but this is also why these wooden remains have survived for so long. Caught up in the wattle fencing, are numerous sherds of medieval pottery, animal bone and other organic material.

The bulk of the pottery is a mix of medieval fragments which date to around the 13th-14th centuries AD. The wattle fencing therefore appears to part of a very early eastward expansion of the medieval burgh.

This rare discovery of preserved wooden structures opens a window into Glasgow’s past when it underwent its first wave of major expansion. It is remarkable that in the same year that Glasgow will celebrate its 850th anniversary of receiving burgh status, some archaeological evidence of those beginnings have been discovered.

Further analysis of the wood and other material will be carried out in due course, following the excavation works.

Construction works will commence after the completion of the archaeological excavation. The archaeological team is expected to complete their excavation by November. Once the site is cleared, construction will commence, with completion anticipated by summer 2027.

The archaeological work was funded by Wheatley Group and was required as a condition of planning consent by Glasgow City Council who are advised on archaeological matters by the West of Scotland Archaeology Service.

Secrets of Rosemarkie Bronze Age hoard revealed

Share this page

Recently published analyses led by GUARD Archaeology have revealed why a hoard of precious bronze ornaments was buried on the Black Isle almost three thousand years ago.

The Rosemarkie Hoard, prior to micro-excavation

The archaeological finds were discovered during an excavation in 2020-21 ahead of the construction of new homes in Greenside Rosemarkie by Pat Munro (Alness) Ltd). GUARD Archaeology were then commissioned in 2024 to lead the post-excavation analyses. The analyses were undertaken by experts drawn from across Britain including National Museums Scotland, University of Glasgow, various independent specialists and GUARD Archaeology itself.

The post-excavation analyses of finds recovered from Rosemarkie revealed much more, not only about the community who buried this hoard almost three thousand years ago but about the people who inhabited the site before them.

The first evidence of human activity at Rosemarkie was traces of Mesolithic and early Neolithic activity, thought it was only from c. 3300 to 3000 BC that the first demonstrable evidence for permanent inhabitation took place, likely a small farmstead.

Rosemarkie bear bone

A hiatus followed, punctuated sometime between 3000 BC and 2000 BC by one of the most interesting cremation burials from the region, containing the phalange bone of a brown bear buried along with a fragment of a polished flint axehead. The bear bone and axehead fragment most likely had the same significance and meaning as the bear as a whole and the intact axehead. The bear bone may have had a protective function in the deceased’s travel to the afterlife.

Inhabitation of the site returned during the Bronze Age when a sequence of seven roundhouses was inhabited. This phase of settlement was a long lived one, lasting more than six centuries to the turn of the eighth century BC. Detailed examination of the radiocarbon dates suggests that the different roundhouses were not all occupied at the same time but represent a small community, perhaps a family lineage, building successive roundhouses, occupying different spaces in different periods across the site.

One of these roundhouses produced metalworking debris, including identifiable mould fragments for manufacturing a sword, spearhead and sickle along with bracelets. And it was around this same period, towards the tail end of this settlement that a rare and well-preserved late Bronze Age metalwork hoard was buried. Comprising a complete penannular ringed ornament lying on top, a fragment of penannular ringed ornament placed within the complete ornament’s circumference, a cup-ended ornament at the very base and six bracelets.

Through careful minute analysis of every strand of evidence, an enormous amount of information was discovered about the people who buried this hoard at the tail end of the Bronze Age.

The micro-excavation of the Rosemarkie Hoard in GUARD Archaeology’s Finds Lab

The intact penannular ringed ornament, adorned with 37 rings, is the most complete and complicated example of its type yet found in Scotland. Its fragmentary counterpart had 13 surviving rings, and both ornaments were probably made by the same craftworker using the lost wax casting method. This was a very rare process only used in the creation of highly prized objects, and workshops to produce such pieces were few and far between in Bronze Age Scotland. The purpose of these ornaments is unclear as the complete one from Rosemarkie was too small to fit over an average human head, and it showed no signs of being distorted in order to be worn around the neck.

The Cup-Ended Ornament, viewed from either side

X-ray imaging of the cup-ended ornament revealed that it was cast as an entire object with no visible seams or joins. There are several comparable finds known, mostly Irish and made of gold, but its closest parallel is a bronze version from the Poolewe Hoard in the West Highlands. The Rosemarkie example is much sturdier and thicker than any of these, however.

The Penannular Bar Bracelets

The bracelets were also unusual as no two were alike – perhaps they had been contributed by different individuals or households. Three of the six show signs of distortion, suggesting they had been repeatedly worn, and one stood out as the heaviest known penannular bar bracelet yet found in Scotland. While none of the mould fragments found at Rosemarkie matched the objects in the hoard, the objects themselves speak of the local community’s access to a large supply of bronze for the ostentatious display of wealth and status. In terms of where this metal came from, isotope and metallurgical analysis revealed that the metals came from Wales and England, indeed exact and close matches with the bronze from the Carnoustie Hoard, clearly signalling the direction from which Bronze Age smiths in Scotland were sourcing their metals.

Clumped tree bast connecting bottom artefacts in Rosemarkie hoard, with bracken frond in interior of bracelets

What makes the Rosemarkie hoard so significant is not just the metalwork. It’s the organic remains found clinging to it. Bracken stems and fronds were used as packing when the artefacts were buried. Tree bast, the inner bark of a tree, was concentrated around the ornaments, following the curves of each. It also formed a large clump at the base of the pit, entangled with the lowest artefacts. Despite being buried for thousands of years, this mass was strong enough to hold the artefacts in place and would not release its quarry easily.

But when they were eventually teased apart, this mass was revealed to be something very rare indeed: a simple overhand knot that had been tied around the cup-ended ornament when the tree bast was still in pristine condition, binding it to three of the bracelets. A sample taken from the bast provided a secure radiocarbon date for the burial of the Rosemarkie hoard: 894-794 BC, at the very end of the Bronze Age.

There are several possible motivations for the burial of an ancient hoard of bronze. There are founders’ hoards or metalworkers’ stashes – often a range of damaged objects and fragments that could be recycled, as was common practice during the Bronze Age. There are votive hoards, often composed of deliberately broken objects that were thrown into watery places with no chance (or apparent desire) of recovery. And then there are hoards like Rosemarkie – and Carnoustie too. This third category shows another side to the story, representing precious items that were carefully packed, tied together, stacked on top of one another and neatly buried for safekeeping close to a settlement where they could be guarded and easily retrieved when the time came.

The mystery then is not so much why this hoard was buried. But why the time never came for the Rosemarkie Bronze Age community to retrieve their valuable belongings.

The archaeological work was funded by Pat Munro Homes (a division of Pat Munro (Alness) Ltd) and was required as a condition of planning consent by Highland Council who are advised on archaeological matters by the Highland Council Historic Environment Team.

Prehistoric Eden revealed at Guardbridge in Fife

Share this page

Many people who live in new houses may not be aware that they inhabit the same space that prehistoric peoples once inhabited. Two new publications reveal that archaeology that spanned over 10,000 years, from traces of Late Upper Palaeolithic and Mesolithic hunter gatherers, to Neolithic farmers, Bronze Age metalworkers, Iron Age Fort dwellers and medieval kiln burners, once lay where new houses now stand.

GUARD Archaeology’s Guardbridge excavation

The discovery was made by GUARD Archaeology during archaeological excavations between 2017 and 2021 commissioned by Persimmon Homes North Scotland prior to construction of new houses at Guardbridge.

Before the excavation began, the ditches of a fort in the north-east corner of the site had already been identified on aerial photographs.

While most of this fort was left intact, the excavation revealed that it likely originated during the Late Bronze Age and continued through much of the Iron Age until the early centuries AD. Spindle whorls and loom weights attest to the weaving of woollen cloth by the fort’s inhabitants while fragments of shale bracelets demonstrate personal adornment.

But what was really surprising about this site was all the other archaeology found outwith the fort, not just Iron Age but much earlier too.

From earlier in the Bronze Age, the remains of substantial roundhouses were discovered, from which an assemblage of pottery sherds and animal bones were recovered. Metalworking was also carried out here during the late Bronze Age as rare casting moulds for a sword blade and a socketed gouge – a tool used in carpentry – were found. From the porch of one of the roundhouses was found evidence that one of its occupants had once sat there knapping flint for tools.

The site was also used before this, during the Neolithic by some of the first farmers of Fife who left many pits across this site, containing burnt cereal grains, saddle querns and pottery sherds but no trace of their houses.

And before even this, were traces of a temporary Mesolithic campsite. A fire-pit, radiocarbon dated to around 4320-4051 BC, was associated with a cluster of burnt lithics arranged in a distinctive star-shaped pattern, indicative of a tent or shelter, where a small group of hunter gatherers once camped to hunt and fish in the nearby estuary.

And below this was a scatter of flints from around 10,000 BC during the Late Upper Palaeolithic period where some of the very earliest inhabitants of Fife once sat knapping flint tools.

While settlement at this site seems to have drawn to a close around the end of the Iron Age, several medieval corn-drying kilns were also found, dating to between AD 900 and 1300. These kilns were presumably worked by labourers of ‘Segy’ farm. The different construction techniques apparent shows how these kilns changed over time, improving in design and size to meet the growing demand from the growing medieval population of Fife.

These were the last traces of archaeology with origins stretching back in some form or another to some of the earliest occupation of Scotland.

The archaeological work was funded by Persimmon Homes North Scotland and was required as a condition of planning consent by Fife Council who are advised on archaeological matters by the Fife Council Archaeology Service, who considered there to be a potential for hitherto unknown archaeology to be buried at the site due to the proximity of known prehistoric archaeology.

The Monumental Neolithic Halls of Carnoustie

Share this page

A new publication reveals the remains of a significant early Neolithic settlement that GUARD Archaeologists discovered, a focal point for where Scotland’s first farming communities gathered for large scale festivities.

The discovery was made during archaeological excavations undertaken by GUARD Archaeology prior to the building of new football pitches near Carnoustie High School.

GUARD Archaeologists excavating the long Neolithic Hall at Carnoustie

The Carnoustie excavation produced exceptional results, the traces of the largest early Neolithic timber hall ever discovered in Scotland dating from near 4000 BC. This was a permanent structure 35m long and 9m wide, built of oak with opposed doorways near one end of the building. Its large roof was supported by paired massive timber posts. Its walls were wattle and daub panels supported by posts that were partly protected by its over-hanging roof. And its internal space was sub-divided by more postholes and narrow channels marking partitions.

This monumental timber hall, completely alien to the culture and landscape of the preceding Mesolithic era, was erected by one of the very first groups of farmers to colonise Scotland, in a clearing within the remains of natural woodland. It was fully formed, architecturally sophisticated, large, complex, and required skills of design, planning, execution and carpentry.

But what makes this exceptional is that unlike other Neolithic halls in Scotland, which were all discrete solitary structures within the virgin farmland of early Neolithic Scotland, a smaller companion timber hall existed alongside the large Carnoustie Hall. This was still a substantial structure almost 20m long and over 8m wide.

Different sides of Carnoustie Neolithic polished axe

While GUARD’s excavation of the smaller hall revealed a large hearth with charred cereal grains and hazel nutshells consistent with a domestic function, in contrast the excavation of the larger hall yielded evidence for the deliberate deposition of stone artefacts, tantalising traces of the beliefs and rituals of the community that built and used it.

The Carnoustie halls, elevated and prominent in the landscape, were probably close to routeways where people may have congregated naturally at various seasons of the year. The availability of hazel nuts in autumn is a strong indicator that that season was an important one for meeting, feasting and celebrating. The Carnoustie timber halls may have been a focal point, their significance great enough to attract interest from people from a much wider area. We know from the materials found in the Carnoustie buildings that some artefacts came from distant places and represent deliberate deposition, such as fragments of Arran pitchstone, an axe of garnet-albite-schist and a piece of smoky quartz from the Highlands, while other materials were found more locally such as agate, quartz and chalcedony.

After about 200 years, the halls were dismantled and a smaller hall built within the footprint of the larger hall around 3800-3700 BC, but this too continued to receive deliberate deposits of stone tools until about 3600 BC. The site continued to be revisited with evidence of people camping and gathering outside where the buildings once stood, carrying on the seasonal round of activities until around 2500 BC.

This was not the only prehistoric secret that the Carnoustie excavations unearthed.

The Carnoustie gold decorated bronze spearhead

A rare and well-preserved metalwork hoard of a sword within its wooden scabbard, a spearhead with a gold decorative band around its socket and a bronze sunflower-headed swan’s neck pin were found wrapped in the remains of woollen cloth and sheep-skin. This small hoard had been deliberately buried in a pit within the midst of a late Bronze Age settlement sometime between 1118 – 924 BC.

For around 1400 BC, during the Bronze Age, people had returned to this same site at Carnoustie, probably oblivious to its significance to earlier Neolithic communities. A settlement was established here, comprising a single roundhouse, much smaller than the previous Neolithic halls, and replaced three or more times over the following centuries until around 800 BC.

The Carnoustie bronze sword

The best preserved of these Bronze Age roundhouses was positioned over part of the foundations of the large Neolithic timber hall. Like the other buildings it had an entrance facing south-east and during the course of its life it was used as a domestic dwelling, a workshop and also a byre. The overwintering and stalling of domestic livestock within buildings of this period seem to have been a common occurrence. Near this building, the hoard of precious weapons and jewellery was deliberately buried.

The metallurgical and lead isotope studies suggest that all the bronze objects were probably made in Scotland, but from metal imported from further south, eastern England for the bronze and, perhaps the Irish Sea area for the gold. If any object was a direct import, it would be the sunflower pin. The sword was a viable weapon that from the pattern of notches and rebound marks along its blades had probably seen some use in combat, but there was weakness in the core of the spearhead that would have made it vulnerable in use.

Replica of the Carnoustie Hoard

And while the metalwork in the Carnoustie Hoard was impressive enough, the associated organic remains are exceptional. The remarkable preservation of the wooden scabbard, woollen cloth and sheepskin was down to the anti-microbial properties of copper, which all of these items were in contact with.

Map of gold decorated Bronze Age spearheads across Britain and Ireland

This rich hoard of metalwork, together with a shale bangle found in the roundhouse indicate that while the settlement was otherwise very modest and unassuming, its occupants were wealthy and had some status in the wider community. Hoards such as this are rare, but a similar hoard of bronze swords and another gold decorated spearhead found in the 1960s just north of Dundee indicates a shared cultural practice amongst late Bronze Age households for burying wealth such as this for safekeeping. The reason as to why they never came back to recover these prized belongings, however, has been lost to the passage of time.

The last occupant of the Carnoustie site was a small field mouse – investigation of the contents of the spearhead’s socket revealed a considerable amount of fresh-looking grass stems stained by the copper, suggesting that a very small rodent (such as a field mouse) had set up house during the fairly recent past in the socket itself.

The archaeological work was funded by Angus Council and was required as a condition of planning consent by Angus Council who are advised on archaeological matters by the Aberdeenshire Council Archaeology Service, who considered there to be a potential for hitherto unknown archaeology to be buried at the site due to the proximity of known prehistoric archaeology.

Interactions between the Britons and Romans beyond the Roman Frontier

Share this page

Newly published research by GUARD Archaeology reveals how a rare enamelled Roman brooch provides insight into how the local Britons of south-west Scotland interacted with the Roman army during the late second century AD.

Aerial view of GUARD Archaeology’s excavation of the palisaded settlement at the Curragh

Excavations undertaken at William Grant & Sons Girvan Distillery at the Curragh in South Ayrshire in 2020 uncovered an Iron Age settlement dating to a period when southern Scotland had slipped from the grasp of the Roman Empire. The team of GUARD Archaeologists discovered the remains of what had once been a substantial timber roundhouse surrounded by a stout wooden palisade, with a large gated entranceway, likely the dwelling of a wealthy farming household.

During the excavation, the GUARD Archaeologists recovered an enamelled bronze brooch from the bottom of the foundation trench that held the timber palisade in place. What made this find unusual was that it was not local but was of a distinctly Roman origin.

‘This exotic brooch and others like it typically date to the late second century AD, and are most commonly found along the borders of the Roman Empire, in eastern Gaul, Switzerland and the Rhineland,’ said Jordan Barbour, who co-authored the report. ‘Their distribution pattern suggests that these brooches were particularly popular among members of the Roman military forces, so it’s likely that it came north of Hadrian’s Wall on the cloak of a Roman soldier tasked with garrisoning the Empire’s northernmost frontier.’

What makes this artefact all the more interesting is how it was used by the Iron Age inhabitants of this settlement. There was no evidence that it had been worn by a local Briton. Instead, they had buried it as a foundation deposit, a votive sacrifice of sorts, when constructing the timber palisade around their roundhouse.

‘It’s difficult to say exactly why the brooch was deposited within the palisade trench, but we know that ritualised foundation offerings are observed across many cultures, typically enacted to grant protection to a household, and this is certainly a possibility here,’ said Jordan Barbour. ‘As to how it ended up here, there are a few plausible scenarios. It’s the only Roman artefact recovered from the site. If the inhabitants had established regular trade with Roman Britain, we might expect to find a greater variety of Roman objects, but this is a solidly native context. Rather, the brooch is more likely to have been obtained through ad hoc exchange with Roman troops operating north of Hadrian’s Wall, perhaps even taken in battle as a trophy.’

The Curragh Iron Age dwelling was situated atop a rocky plateau with a steep escarpment acting to deny access from the immediate north, and it may well be the case that the dwelling was sited here and enclosed with a strong timber palisade, due to defensive concerns. Although there were no contemporary Roman forts nearby after the abandonment of the Antonine Wall earlier in the second century AD, an earlier first century AD Roman marching camp some two kilometres to the south-west attests to previous military presence in the area, and conflict between the local Britons and Roman soldiers is likely to have been a recurring element of Rome’s intermittent occupation of south-west Scotland.

This palisaded roundhouse was not the only archaeological feature the GUARD Archaeologists found at the Curragh. The enduring appeal of the plateau was proven by an earlier unenclosed roundhouse that was radiocarbon dated to around the seventh century BC, many centuries before the Romans arrived in Britain. And traces of even more ancient inhabitation were evidenced by the recovery of pottery dating to the early Neolithic period, when a large timber monument was constructed here, between 3,700 and 3,500 BC.

Uncovering Moredun farmstead

Share this page

GUARD Archaeologists are leading an excavation at Moredunvale in Edinburgh to uncover the remains of Moredun Mains farmstead that once stood on this site. And members of the public are welcome to join in and participate.

Depicted on the Ordnance Survey’s map of 1877, Moredun Mains comprised three buildings arranged in an inverted U-shape on plan. The excavation is targeting the archaeological remains highlighted by a previous geophysical survey in order to reveal traces of life on this farmstead. 

The farmstead isn’t the only archaeology that survives around Moredunvale. Traces of a prehistoric landscape survive in the surrounding area, standing stones, prehistoric burials and random findspots of stone axes have previously been recorded close by.

We don’t know what the excavation might uncover, but there is certainly a story to be uncovered and told!

Come along and join in! No prior experience required.

Monday 10 February – Wednesday 19 February 2025 from 9am to 3pm each day, including the weekend.

Archaeological Research Award Nomination

Share this page

A community archaeology project enabled by GUARD Archaeology has been nominated for an Archaeological Research Project of the Year Award.

Working together with the Arthur Trail Association, local volunteers and heritage groups, and specialists from a variety of universities and institutes including the National Museums of Scotland and the Universities of Aberdeen, St Andrews and Stirling, the Drumelzier’s Hidden Heritage project investigated the archaeological roots of Drumelzier’s Merlin legend.

Until the fieldwork got underway in 2022, Drumelzier’s folklore was assumed to have simply originated from a wandering medieval minstrel, who had weaved random nearby landmarks into a local version of a tale that was widely known across medieval Europe.

The team of archaeologists and volunteers investigated Tinnis Castle, where according to the Drumelzier legend the protagonist was imprisoned by a Dark Age tyrant. The archaeological evidence they uncovered revealed that the hillfort underlying the castle was occupied around AD 600, precisely when the story was set and which has the hallmarks of a lordly stronghold of the time.

The team also undertook a geophysics survey of ground where according to the local legend the protagonist was buried on the banks of the Tweed and Powsail Burn. This survey revealed that while there is nothing at the spot marked on maps as the reputed location of Merlin’s Grave at Drumelzier, there is indeed an archaeological feature resembling a grave nearby to this.

The new archaeological evidence does not prove that the local tale was true, but it does demonstrate that the legend very likely originated in Drumelzier itself.

These awards are voted for entirely by the public – there are no panels of judges – so anyone is free to choose the projects, publications, and people they would like to win.

Voting closes on 10 February 2025, and the winners will be announced on 1 March as part of the Current Archaeology Live! 2025 Conference.

Archaeological remains of early medieval workshop discovered on Islay

Share this page

An early medieval workshop built over the ruins of an earlier Pictish-style building reveals a snapshot of life in the early Scots kingdom of Dál Riata.

Recently published analysis of the archaeological evidence recovered by GUARD Archaeology Ltd from Coultorsay on Islay has revealed an iron smelting workshop located within the earlier remains of a figure-of-eight building. This hive of activity was dated to between the sixth and ninth centuries AD when Islay was part of Dál Riata, the early medieval kingdom of the Scots centred upon the royal fortress of Dunadd and which covered modern-day Argyll and Bute.

Metalworking waste, the upper part of a rotary quern, a bone needle and shale bracelet fragments were recovered from several of the features associated with the buildings. Shale bracelets are rare in the Inner Hebrides; these are the only examples known from Islay. The shale probably came from central Scotland.

Over time a change in function took place, from domestic use to that with an industrial focus, which took place after the domestic building had fallen into a state of disrepair. In contrast to many known metalworking workshops from early medieval Scotland, which were often enclosed within royal or lordly strongholds, the Coultorsay workshop was a relatively modest structure. It appeared to have been used for smelting bog ore to extract iron bloom which could then be made into tools and weapons somewhere else.

Very few sites dating to the early medieval period have been excavated on Islay with most known sites being ecclesiastical in origin, such as chapels and burial grounds, several with fragments of early cross slabs. This makes the figure-of-eight building particularly important and provides new information about those living on Islay out-with ecclesiastical sites. The similarity of the earlier figure-of-eight house to cellular Pictish buildings suggests that this form of architecture was more widespread across Scotland than previously envisaged.

The early medieval landscape of Islay was probably characterised more by slight buildings, such as the Coultorsay figure-of-eight house, in which the majority of the population resided but leave little trace, than the more substantial forts that are the more visible remnants of early medieval Scotland.

The GUARD excavation also revealed the remains of prehistoric structures and activity from the Mesolithic to the Iron Age across the hillside terrace where the workshop lay. The evidence seemed to suggest relatively transient activity during the Mesolithic and Neolithic periods before more settled occupation began in the Late Bronze Age and Iron Age followed by a gap of about 500 years before occupation re-appeared during the early medieval period.

These archaeological remains were first encountered in 2002-2003 during excavations on the site of the now demolished Carrick Halls in the centre of the historic town of Ayr. A further intervention on the site in 2021 by GUARD Archaeology Ltd was made in advance of development, which allowed specialist analyses of the evidence from the earlier archaeological work to be undertaken.

The earliest activity identified on the site was the creation of a ditch that formed a medieval burgage plot boundary between the mid-twelfth and early thirteenth century, in the period immediately preceding or during the initial town expansion. The boundary was reinforced in the middle to late thirteenth century by an oak planked fence with roundwood stakes erected in the middle of the ditch.

The location of the ditch is important in understanding the expansion of medieval Ayr to the south-east and it continued in use into the fourteenth century after which it was filled in. Evidence of iron smelting recovered from the ditch deposits indicated that metalworking took place nearby. The presence of Scottish medieval pottery and especially of imported French wares within the ditch deposits indicates that during the Middle Ages, Ayr, a royal burgh, was also an important international trading port.

The original excavations and subsequent analysis of artefacts found in the ditch revealed changes in land use and occupation of the burgage plot into the fourteenth and fifteenth centuries. The domestic uses of the land were brought to an end by the accumulation of windblown sand across the southern part of the town. A wide variety of plants were found growing on these deposits indicating that the plot may have remained as waste ground into the post-medieval and modern periods, prior to the construction and the eventual demolition of Carrick Halls in the twentieth century.

Work begins to reveal secrets of Bronze Age hoard discovered in Rosemarkie

Pre excavation photograph of hoard prior to excavation in GUARD Archaeology’s Finds Lab

Recent laboratory investigations of a Bronze Age hoard, by GUARD Archaeology, have revealed rare organic plant remains intertwined with nine bronze bracelets and necklaces buried sometime around 1000 BC.

The Bronze Age hoard was discovered during excavations conducted prior to the development of new 3 and 4 bed homes by local developer, Pat Munro Homes (a division of Pat Munro (Alness) Ltd) at Greenside in Rosemarkie, in Highland Scotland.

What makes the hoard especially significant is that it was not an isolated find with little context to explain it, but was discovered within the middle of a prehistoric settlement, a Bronze Age village comprising at least six roundhouses and also a Bronze Age cist grave. Altogether GUARD Archaeology’s analysis of these archaeological remains will shed light upon the lives, beliefs and deaths of Bronze Age highlanders. This will add to what GUARD Archaeologists have gleaned from another Bronze Age hoard they excavated in Carnoustie on the east coast of Scotland, also found within a Bronze Age village, which may altogether reveal aspects of Bronze Age culture apparent across Scotland.

The laboratory excavation conducted by a team of GUARD Archaeologists alongside Conservator, Will Murray, from the Scottish Conservation Studio revealed nine bronze artefacts, including one complete neck ring, one partial neck ring, six penannular bracelets and one cup-ended penannular bracelet. Remains of plant/organic material was also recovered, comprising fibrous cords tied and knotted around some of the bronze objects.

“The recovery of the artefacts was successfully carried out under the controlled conditions necessary to preserve these highly significant objects, particularly the very delicate organic cords that tether some of the objects together,” said Rachel Buckley, who led the laboratory excavation. “Where bracelets were held together with organic material, these were recovered as a group to allow further detailed study. While there are other examples of hoards where it has been postulated that items were bound together due to their positioning, the vegetation in the Rosemarkie hoard has survived for approximately 3000 years, proving that these artefacts were held together.”

The survival of the organics is likely in part due to the anti-microbial properties of copper (in the bronze), where the corrosion products from the copper adhere to the organics and preserve them.

Over the next few months, the team of specialists brought together by GUARD Archaeology will be examining the various strands of archaeological evidence that may explain why the hoard was buried here.

“That the hoard was buried under a single homogenous fill within a shallow pit with little extra room for anything other than what was found within, indicates that this was no accidental loss,” said Iraia Arabaolaza, who is managing GUARD Archaeology’s analyses. “It would seem that the shallow pit was dug to the required length and depth to accommodate the items, before then being quickly backfilled. It may be that it was intended as temporary storage with the intention of recovering the hoard at some stage. The evidence from the surrounding settlement may reveal whether it was not just the hoard that was abandoned but the settlement as well.”

The archaeological work was funded by Pat Munro (Alness) Ltd and was required as a condition of planning consent by Highland Council who are advised on archaeological matters by the Highland Council Historic Environment Team, who considered there to be a potential for hitherto unknown archaeology to be buried at the site. Hamish Little, Senior Manager, Pat Munro Homes said, ‘It’s been a great experience for the team at Pat Munro Homes to work with the archaeologists at our development at Greenside, Rosemarkie and also be part of the team that uncovered the Bronze Age artefacts. We are hoping to work together with the archaeologists, and other partners in the coming months to involve the local secondary school, Fortrose Academy in learning more about its historical significance and getting pupils involved in helping to design a permanent feature on/near the site that will tell the story and can be shared with the local community and visitors to the area.’
