2018 Project Design: what will the BRP be focusing on this year?

Before the start of the excavation season the BRP directors compile a list of aims and objectives based on what we we want to achieve during this period. This includes how we plan to excavate and record the site, strategies for undertaking post-excavation research, our aims for teaching both staff and students, and what we hope to achieve in terms of our outreach.

We have created a detailed Project Design, which provides background information about the site and previous work undertaken. This is then used to inform our detailed plans for the summer, as set out in the latter part of the Project Design. You can access this document here: Bamburgh Research Project Design 2018

Overview

This year we will be focusing our attention on excavation of Trench 3, where the main body of our teaching will be undertaken. This will be supported by our finds and paleoenvironmental teams.  We will also be prepping the bulk of the medieval and early medieval metalwork to go for specialist analysis thanks to funding from the Society of Antiquaries. Recent funding from the Mick Aston Archaeology Fund has also allowed us to expand our outreach activities, which you can learn more about here: 2018 Outreach Activities

Pottery Assessment for Trench 8, Bamburgh Castle

As part of the BRP’s ongoing post-excavation analysis of Trench 8 in the West Ward of the Castle (click here for a full description of the research project funded by the Royal Archaeological Institute) we have commissioned specialist analysis of the pottery recovered from the trench.

Pottery reports are hotly anticipated by many archaeologists, as they often offer insight into site function and phasing. The Bamburgh Research Project recovered 651 sherds of pottery from Trench 8 in 2006. The assemblage is predominately dated to the 13th-14th centuries, which is not unexpected, as a series of large medieval midden deposits cover much of the West Ward excavations around Trenches 3 and 8.

The most significant element of this assemblage is a type of 12th-14th century pottery that has not been found elsewhere and has been termed ‘Bamburgh ware‘. Bamburgh ware makes up a large portion of the assemblage (24%). We have noted this pottery elsewhere in the Inner Ward of the Castle. However, in order to understand its manufacture, source of the raw materials, function etc. it is important that we recover and record as many fragments as possible.

There was evidence of earlier pottery types, including Stamford ware (10th-12th century) and Gritty ware (11th-13th century), two of which were hand-made.

Notably, no Roman pottery was identified in the assemblage, despite Roman period contexts been identified through Radiocarbon dates.

We will use the data recovered from the pottery assemblage and amalgamate it with the glass, lithic and metalwork reports. We have also undertaken five radiocarbon dates, which together with the paper archive from the excavation, will be used to create a detailed stratigraphic sequence and interpretation. This will aid future excavation in the West Ward.

Further Funding Success for the BRP with the CBA’s Mick Aston Archaeology Fund

The Bamburgh Research Project have kindly been awarded £988 from the Council for British Archaeology’s Mick Aston Archaeology Fund, which is supported by Historic England.

The BRP will use the funding to enhance our outreach outputs. It will facilitate free, daily, trench-side activities for visitors to Bamburgh Castle, encouraging them to explore the history of the site (prior to the upstanding remains), through hands-on activities and guided tours. It is also the aim of the project to undertake free activities within Bamburgh Village for those unable to access the Castle. This will engage both local residents and tourists. The latter will be supported by a free evening lecture series, throughout the duration of the excavation.

Trench-side and and village activities will include:

  • Hands-on teaching sessions undertaken by BRP pottery specialist and animal bone specialist
  • Finds washing
  • Finds sorting
  • Finds illustration
  • Handling collection (animal bone, pottery etc.)
  • ‘Show and tell’ activity, where more significant/rare items are displayed and discussed by BRP staff

The funding will primarily be used to purchase equipment and hire venues for the village activities.

A timetable of planned activities will be added to the blog in due course.

Glass and Lithic Assessment Results for Trench 8

As part of the BRP’s ongoing post-excavation analysis of Trench 8 in the West Ward of the Castle (click here for a full description of the research project funded by the Royal Archaeological Institute) we have commissioned specialist analysis of the lithic and glass recovered from the trench.

The lithic and glass assemblages are small but still important when trying to date and interpret the complex stratigraphy in the trench. We recovered ten worked flints, five of which had been re-touched. This assemblage included a probable Mesolithic microlith blade, a thin side and end scraper (see below) and examples of microdebitage. With the exception of the blade fragment, the flint was undiagnostic in terms of their date, which means they could date from the Mesolithic to the Bronze Age. However, as we are currently excavating the early medieval phases of this area of the West Ward and recently recovered pockets of disturbed Roman material, evidence of prehistoric activity is welcome and is indicative of what we might expect in future seasons.

Retouched thin side and end scraper from context 825

Only two fragments of glass were recovered from Trench 8. One was a post-medieval utility bottle, made from thick, olive green glass. The second fragment is much earlier. The fragment is very small, very pale blue-green to colourless, thin and flat. It is almost completely covered in opaque surface corrosion, even on the break surfaces. This obscures the view of the interior glass, but also suggests that the glass is potash-based and dates to at least the late Anglo-Saxon period, and more likely to the medieval period. Based on our current understanding of the stratigraphy in this area, it is suggested that this fragment came from the bottom of the twelfth to thirteenth century midden deposit, which covers much of the early medieval deposits in this area.

We will combine this information with that available from the metalwork and pottery analysis, plus the radiocarbon dates to hone our understanding and interpretation of Trench 8.

2018 Funding Success with the Society of Antiquaries of London

The Bamburgh Research Project are pleased to announce that the Society of Antiquaries of London have kindly awarded us £4700 to undertake continuing post-excavation analysis of the material recovered within the West Ward of Bamburgh Castle.

The project ‘Forging Castle Space’, will focus on the metalwork recovered from early medieval contexts in Trench 3. The funding will allow us to assess and plan the conservation of 7,200 fragments of early medieval metalwork, spanning the 8th-11th centuries, plus conserve a 25% sample of all styca coins recovered.

Upon completion of the project the metalwork will be better understood in terms of its function, origin and date, plus its purpose for deposition within an associated building, likely used for working metal (You can read more about the building here: Castling, J. and Young, G. L. 2011. A 9th Century Industrial Area at Bamburgh Castle, Medieval Archaeology, Vol. 55, 311-317). This data will allow us to better understand the function of the building, its associated area and the broader 8th-11th century horizon in this area of the castle. The data generated will also inform ongoing excavation and aid us in our attempt to contextualise earlier excavations (1959–74) for which we only have a partial archive surviving.

The long-term goal is to establish the character and significance of early medieval activity, as this was pivotal in creating the spatial and material precedent upon which the post-Conquest castle complex developed.

We have already made great strides towards understanding this period in the West Ward, as we have recently completed the post-excavation analysis of Trench 8, which sits immediately adjacent to Trench 3. Funding from the Royal Archaeological Institute has enabled us to determine a stratigraphic sequence from the modern to the Roman period using the artefacts recovered and C14 dates to identify and date contexts. You can learn more about this project here: Trench 8 RAI Grant.

Medieval and Anglo-Saxon Metalworking at Bamburgh Castle: the results of the Trench 8 assessment and conservation

As part of the BRP’s ongoing post-excavation analysis of Trench 8 in the West Ward of the Castle (click here for a full description of the research project funded by the Royal Archaeological Institute) a collection of 165 metal objects were sent for x-ray and assessment. Of these, the copper alloy and lead objects were found to be in good condition but the iron objects were poorly preserved with significant surface loss on some.

Of the metal artefacts recovered, 19 were recommended for conservation. Funding was provided by Bamburgh Castle to undertake the conservation where the artefacts were appropriately cleaned and stabilised. These have now been returned to the Castle in the hope that some will go on long-term display within the Castle’s archaeology museum and the rest will be carefully stored for future research.

The 165 objects ranged in date from 7th century – 1970’s. The majority of the collection is made up of medieval iron nails (85) with various other objects, including horseshoes, a key, bolts and a buckle also dating to this period.

The Early Medieval period is also well represented within this collection. This is not unexpected as Trench 8 lies in close proximity to the 9th-10th century metalworking building located in Trench 3, where a large styca hoard and other examples of Anglo-Saxon metalwork have been discovered (for more info see Castling, J. and Young, G. 2011, A 9th Century Industrial Area at Bamburgh Castle, Northumberland, Medieval Archaeology, Medieval Britain and Ireland, Vol. 55, 311-317). Earlier excavations undertaken by Dr Brian Hope-Taylor (see link above) also recovered the famous Bamburgh Sword (click here to watch a lecture about the Bamburgh sword) and axe head in this area. The Anglo-Saxon material recovered from Trench 8 included a possible clench-bolt, which are often associated with boat building, wagon and building construction, a pair of shears indicative of sewing or personal grooming, a copper alloy strap end with parallels from the Anglo-Saxon port of Hamwic and three copper alloy styca coins.

There are 23 fragments of lead off cuts, which suggests lead was being worked in the vicinity.

Notably, evidence of Brian Hope-Taylors earlier excavations undertaken in the 1960’s and early 1970’s is seen in the metalwork with a 1974 penny – the last year of the earlier excavations, aluminium foil and modern nails all being recovered by the 2006 BRP excavation team.

The team also found in-situ finds tags from Hope-Taylor’s excavation, which have helped us understand some of the surviving paperwork and find spots of key small finds from his excavation.

There are numerous other objects that will require further research to date and identify parallels. These include a iron blade, hooked tag and socketed arrowhead, plus a probable copper alloy weight for a fishing net.

There is still further research to be undertaken on the metalwork assemblage from Trench 8 but the initial results suggest the site was particularly active from the 8/9th century through to the 14th century. The information will be combined with that provided from the other material assemblages, such as the pottery, glass and lithic, to build a picture of life in the West Ward. This in turn will be used to support the data gathered from the larger BRP Trench 1 and Trench 3 excavations, and contextualise the unpublished and partial record from the Hope-Taylor excavations – one of the BRP’s primary research objectives within the Castle.

Future blog posts will look at some of the other material assemblages and report on the radiocarbon dates that will help provide clues toward the dating of various complex features observed in Trench 8.

Excavation Season 2018

We are running a little later than usual in announcing details about our summer excavation, but plans are in hand and we aim to make some more detailed announcements this month.

Trench 3

Trench 3 with the new strucctural surface exposed in the narrow trench. Looking forward to seeing more of this in 2018!

Excavation at Bamburgh Castle will be five weeks this summer, as it was last year. Given that excavation within Trench 1 was completed last season, this year we will only be excavating in Trench 3. Our aim will be to expose an 8th century structural surface within the trench, but we are also seeking to move our post-excavation forward as well. It will be slightly smaller team than usual so probably best to book early, if you are able, once the website is updated. In the mean time if you want to be added to an email list to be contacted as soon as the details are finalised then do get in touch graemeyoung@bamburghresearchproject.co.uk

Geoarchaeology at the Bradford Kaims

Becky Scott – Assistant Supervisor (Geoarcheology) and PhD Candidate, University of Reading

Following on from our blog post about the geophysical survey carried out at the Kaims this year, we have been busy ‘ground-truthing’ the anomalies seen just to the North of Trench 6 – that is, identifying whether the magnetic anomalies seen on the survey are archaeological features or not. Of course, like most endeavors, we have had varying degrees of success! The first few test pits that were dug contained nothing but colluvium (sediment that has been deposited downslope, often known as hill or slope wash) even after digging up to a metre. We then decided to take some cores around the area that showed the magnetic anomalies to the North of Trench 6 using the Dutch auger, which is essentially a long pole about 1 metre long with a T-handle and a screw-like head at the bottom which collects and retains sediment. Dutch augers are particularly useful for hard and wet sediments so worked very well through our silty clay colluvium. After taking a number of cores (with the excellent help of our two Young Archaeologists Club competition winners!) we eventually came up with some lovely layers of charcoal and burnt material, so we set to work digging three more test pits. Two of these test pits were more much more successful, particularly Test Pit 75 which showed a charcoal layer almost 30cm thick (see Figure 1 below).

Figure 1

Figure 1. SE-facing section of TP75 showing three very distinct layers: Top soil, colluvium and a ~30 cm thick charcoal and stone rich layer.

 Test Pits in the wider landscape

As well as ground-truthing the results of the geophysical survey, we have also been collecting samples for geoarchaeological analysis from some larger test pits dug by our new friend, The Big Digger. For those unfamiliar, geoarchaeology is an approach to archaeology which utilises techniques from the earth and environmental sciences to answer archaeological questions. In real life it mostly involves getting really, really muddy and pondering sediment sequences for long periods of time…

The main aim was to take samples from the colluvium in the wider landscape (identified during coring by Dr. Richard Tipping and Coring Supervisor Anna) for radiocarbon and pOSL (portable Optically Stimulated Luminescence) dating and micromorphology (the study of in-situ soils and sediments in thin section) to provide us with a proxy for human activity in the immediate area (see Figure 2 below). Colluvium results from human activity, particularly agriculture, and therefore can tell us about past agricultural processes in the wider landscape as it represents a period of soil erosion due to ploughing, over-grazing, and the removal of trees. Under gravity these sediments are then transported downslope. Sometimes, if geoarchaeologists are lucky, ancient soils will be preserved underneath the colluvium allowing us to infer a period of stability and identify the environmental conditions before the land was cleared. The nature of the colluviation also gives information about what processes caused it to erode, and how high the energy of its erosion was.

Figure 2

Figure 2. Students Oda and Daniel taking OSL samples in the extended section of T6 with Anna and Becky, and Director Paul also working hard in the background. Samples for pOSL were taken vertically down the sequence from the section by inserting tubes into the face of the section, removing gently and quickly securing with tape to ensure no light entered the samples. They were then labelled with a sample number and an arrow indicating the end that had not been exposed to light, ready for laboratory analysis.

They were then labelled with a sample number and an arrow indicating the end that had not been exposed to light, ready for laboratory analysis.

pOSL will hopefully allow us to identify the rates of erosion in the area, with the radiocarbon dates from the peat below effectively acting as an ‘anchor’ to identify when this erosion (and therefore agricultural clearance) began. Once the thin sections are made, micromorphology will allow us to identify the depositional and post-depositional processes occurring at the microscale.
