A story half-told: Caister Castle

Castle Studies Trust patron John Goodall explains the reason behind his latest book The Castle (Yale University Press) using the intriguing example of what happened to Caister Castle after the death of Sir John Fastolf, the castle’s owner.

Those who have seen a copy of The English Castle (2011), which I published more than a decade ago, may be surprised to learn that it was originally intended to be a short book. The attempt to tell the story of the architectural development of the castle from the Norman Conquest of 1066 to the Civil Wars of the 1640s, however, inexorably and necessarily transformed it into a long and richly illustrated one. So long and so richly illustrated that, when it was completed, I never thought I would wish to return to the subject.

Several friends and at least one reviewer, however, observed that the story it told about the history of the castle was incomplete. If the castle was—by my own definition—the residence of a noble made magnificent by the trappings of fortification, then what was there to say about such buildings in later centuries? They were right, of course, and this new book The Castle. A History is an attempt to complete a story that my previous book—for all its length and scale—only partially told.

Rather than continue the narrative in the same form, however, and produce another door-stopping volume, I thought I would try and condense the whole story of the castle from beginning to end in a single and much shorter volume. In this sense, this second book on the subject of castles is actually cast in the intended form of the first that I planned more than a decade ago. To make this possible I also decided to approach the subject in a way that I hope will strike readers as both unexpected and engaging.

Presented here are effectively a series of anecdotes organised in a huge chronological span of two millennia and drawn from every kind of source, from chronicles to sermons, poetry to building accounts, and novels to correspondence. All of them are about castles or take place within the context of these buildings. There are also some images that are treated in the same way. The result is a story presented through many different modes and voices across a span of over two millennia.

Part of the joy of this approach is that the book can be read in many different ways, either as a volume that the reader can dip into casually at any point or as an overarching narrative. More importantly, however, it allows for the exploration of specific detail in a way that is impossible in a conventional narrative history. In the process, the human dimension of the past is also brought to the fore. As an added benefit it allows for the exploration of small episodes and the specifics surrounding them that would be impossible in a conventional narrative history.

What could be better as a taster for the volume, therefore, than take a relatively well known anecdote about a siege that didn’t make the final cut for reasons of length and present it in the formula adopted in the book.

Caister Castle Great Tower from the Bailey copyright John Goodall

In the autumn of 1459 the childless Sir John Fastolf, a wealthy veteran of the French wars, tried from his deathbed to finalise the details of a long-discussed proposal to turn his seat at Caister—variously described as a ‘great mansion’, ‘castle’, ‘manor’ and ‘fortress’—into a Benedictine Priory and almshouse. When he died on November 5, his trusted administrator John Paston announced that Sir John had issued a final will by word of mouth. This nuncipative will gave Paston control of all Sir John’s property and tasked him with founding the priory. We will never know the truth of Paston’s assertion. Given the value of what was at stake, however, not to mention England’s descent into the Wars of the Roses, it was never going to go unchallenged.

After the Battle of Edgecote on July 26, 1469, Edward IV was briefly imprisoned and royal authority collapsed. A wave of violence broke as individuals across the kingdom took the opportunity to settle scores. Among them was the Duke of Norfolk, who decided to seize Caister by force. The ensuing siege lasted about three weeks and details of it are recorded in the writings of a former secretary of Sir John Fastolph, the scholar, historian and topographer, William Worcestre. He was an excluded executor of Sir John’s will:

Memorandum that at the feast of the Assumption of the Blessed Mary [15 August] 9 years ago was the siege of Caister; Saint Bartholomew’s [Day, August 24] was a cruel day with guns fired at the castle [castrum]; the siege lasted for five weeks and three days.

Here follow the names of the men at arms besieging the castle and fortalice [castellum et fortalicium] of Caister Fastolf, beginning on Monday, [August 21] before the feast of Saint Bartholomew in the ninth year of King Edward IV, the King being at Coventry; and the siege lasted until September 27.

John, Duke of Norfolk… [followed by a list of 37 other knights and squires].

The names of certain defenders of the siege against the Duke:

John Paston junior, esquire, defending the siege in place of John Paston knight his brother, during his absence, being with:

Dawbeney esq slain with a quarrel

Osbern Bernay esq

Valets: Osbern of Caister valet; Sander Cokby of Maltby valet; Richard Tolle valet; Mundynet, born in France; Thomas Salern of Caister; servants of John Paston junior John Vincent; W. Vincent; W. Wod; N, Bylys; Robert Owmond of Maltby. Davy Coke, servant of John Fastolf; John Roos of Filby; John Osbern of Filby; John Norwood; Raulyns, a stranger; William Peny, a soldier from Calais; John Loe of Calais; Mathew, a Dutchman; Thomas Stompys, handless, and wished to shoot for a noble; John Pampyng of Norwich; John Chapman, soldier of the Duke of Somerset; J. Jaksone of Lancashire; J. Sparke of Marsham

And first the said Duke John, before laying siege to the said castle, a week beforehand, sent Sir John Heveningham, knight, a cousin of Sir John Fastolf, to John Paston, junior Esquire, lieutenant of his brother, John Paston knight, for the safekeeping of the said castle for the use of his brother during his absence on service and on business…. The Duke said that he had bought the castle from a certain accursed William Yelverton Justitiar of Norfolk named one of the executors of Sir John Fastolf knight and lord of the castle, although it was against his will and testament that it should be sold, for he had ordained in his testament that it was to be a house of prayer and for poor people, to be founded to pray for ever for his soul and those of his parents. The said lieutenant of Caister refused to deliver up the castle, for that he had not taken custody of it from the Duke, but only from John Paston his brother. Afterwards, within ten days, that is on the said Monday, the Duke himself with his army to the number of 3,000 armed med laid siege to the castle. Three parts of it were under fire from arms called in English guns and culverins [gonnys culveryns] and other pieces of ordnance of artillery, with archers etc.

William of Worcestre, Itineraries (trans. J. Harvey)

The list of the garrison is curious because it shows that besides a force of locals and servants (including the handless Stompys, who ambiguously wished to ‘shoot for a noble’ or gold coin) there was a smaller group of mercenaries, many of them with experience in Calais, then an English frontier town in France. The latter appear to have been given command of sections of the fortifications and in the months before the siege helped train the former. The fighting seems to have been restricted to bombardment followed by negotiation, at the end of which the castle capitulated. Beside the unfortunate Daubeney, whose brass survives at nearby Sharrington Church, two of the besiegers were also killed by a single cannon shot. The Duke issued terms of surrender on September 26 that:

John Paston and his said fellowship being in the said manor shall depart and go out of the said manor without delay, and make thereof deliverance to such persons as we will assign, the said fellowship having their lives and goods, horses and harness, and other goods being in the keeping of the said John Paston, except guns, crossbows, and quarrels, and all of the hostelments to the said manor annexed and belonging…

September 26, 1469, passport to the besieged

The siege was one episode in a long battle over Fastolf’s will but Caister never became a monastery (a 20th-century equivalent would be the donation of a house to the National Trust). Instead, much of his land was used to endow Magdalen College, Oxford.

Viewscapes from Trim Castle

Scott Stull, archaeology lecturer at SUNY Cortland, looks at the results of an interdisciplinary led by Physicist Michael “Bodhi” Rogers, that he took part in looking at the landscape and viewscapes of Trim Castle.

Trim Castle, in County Meath, Ireland, was built starting in 1187 by the De Lacy family as part of the Anglo-Norman conquest of Ireland. After a long history of conflict, disputed ownership, expansion, change, and decay, the castle was finally abandoned in the mid-sixteenth century when it was described as being full of cattle and dung. The medieval landscape around Trim is remarkably well preserved, including the walls of the town, a fourteenth-century bridge over the River Boyne, a variety of religious institutions, and the farmlands, called the Porchfields, which still have their ridge and furrow plough marks.

In 2016 and 2017, Michael “Bodhi” Rogers led a team of students to digitally record Trim Castle and the surrounding landscape. That scanning project was described in Archaeology Ireland (https://www.jstor.org/stable/pdf/26565802.pdf). The results of that project allowed further study and analysis of the landscape, and specifically the viewscape, of Trim Castle. In a three-way interdisciplinary project, Scott Stull (archaeology), Michael “Bodhi” Rogers (physics), and Michael Twomey (medieval literature) looked at Trim Castle and how the views from the castle were carefully constructed as part of the creation of medieval power and authority.

The starting point for this study, which is a chapter of the upcoming volume, Bailey, Kinsella, Thomas (eds) Architectural Representation in Medieval Textual and Material Culture (Arc Humanities Press, 2022), is the concept of the cultural landscape. The cultural landscape is how people shape a landscape and put meaning on it, to influence perception, behaviour, and patterns of social interaction. It can be practical, such as food production, or it can be tied to belief systems, such as religious sites, places associated with an ethnic or group identity, or associated with structures of power and authority. Castles, while often associated with military activity, embody most of these elements, and as part of the cultural landscape help create beliefs that support those practices and perceptions.

Viewscapes are a specific aspect of a cultural landscape, and in this case are the views from the castle. At Trim, the castle is placed to oversee the town, roads, bridge, farm fields, and religious institutions. There are a variety of ways to identify and record viewscapes, such as with mapping and GIS systems (for example: Lisa Karen McManama-Kearin, The Use of GIS in Determining the Role of Visibility in the Siting of Early Anglo-Norman Castles in Ireland, BAR British Series 575, Oxford: British Archaeological Reports, 2013). Our study, overseen by Bodhi Rogers, used ground-based lidar to make a 3D record of Trim Castle and its surroundings. The result of the recording is effectively a 3D photograph which you can examine from any angle or point in space. This allows us to see from windows which are inaccessible physically, or from spots which have been lost due to decay or collapse over time.

While a useful modern tool, viewscapes were a fundamental part of the medieval understanding of castles. We see castles used as viewing platforms, as symbolic places of literal and figurative elevation, and as part of medieval romances where the view from the window represents both the desire and distance of a romantic attraction. In many cases, the lady views the desired knight from the castle window, and the knight is inspired by the glimpse of the lady in the window, affirming the ideals of courtly love. Religious allegories have the castle as a tower of morality, and the viewscape is often overlooking humanity in all its faults and mundanities. By looking at medieval literature, we can gain an understanding of the medieval mindset.

Combining the physical context of a castle with the medieval mindset allows us to gain a more complete understanding of medieval life. The nobility used castles as structures of power and created a cultural landscape which made that system of power seem normal and natural. Castles were a central part of everyday life in medieval Europe, and the lived experience of medieval people was shaped by the created landscapes in and around a castle. At Trim, the castle overlooked the social and economic centres of the community, from the Porchfields to the monasteries. The viewscapes from the castle were specifically created to reinforce the position of the De Lacy family and its successors over the lands and cultural landscape in Trim. Trim castle was the dominant element in both the physical and social landscape.

Castle Studies Trust is going on its travels in 2022

In its latest round of grants the Castle Studies Trust has awarded £34,000 to five projects including two projects outside the UK. As well as covering a wide geographic area the projects will also undertake a broad range of technics to boost our understanding of castles.

Dating medieval towers in the hinterland of Medieval Chalkida, Greece:

Stand-alone medieval towers, often part of castles or larger fortifications, are common in Central Greece. Often thought to have been built by the Frankish nobility during their period of dominance between 1204-1470, there is minimal evidence to back this up. By taking wood and mortar samples, the project aims to answer that question.

The present project forms part of the five-year survey ‘Beyond Chalkida: Landscape and Socio-Economic Transformations of its Hinterland from Byzantine to Ottoman times’ (authorised in July 2021 by the Greek State)

Samples will be taken from six towers of wood used laterally within tower walls to increase their structural strength, and mortar from within the core of the walls (both therefore probably

contemporaneous to the original period of construction). Specialists will use dendrochronological and

Carbon 14 methodology for the wood (8 samples), and optical microscopy, Scanning Electron Microscopy (SEM), and X-ray fluorescence (XRF) and diffraction (XRD) Spectroscopy (mortar – 21 samples).

Work will start at the earliest in late 2022 and may not actually take place until next year due to the time it is likely to take to get official permission from the government. 

Kilmacahill, Co. Westmeath

Geophysical survey of deserted medieval settlement close to Jamestown motte & bailey castle. The aim is to understand the morphology of settlement and its relationship with the castle and medieval monastery.

This survey will contribute to a larger project: the Human-Environmental Exchanges in the Landscapes of Medieval Ireland Project (HELM Project) which aims to use a combination of multispectral imaging, UAV drone survey along with geophysical survey to gain a much better understanding of the form of the deserted medieval village through non-invasive methods.

At time of writing it was unclear when the survey will take place.

Pontefract, West Yorkshire

The project funded will be a geophysical survey of two parts of the castle, which during its history was the main royal castle in Northern England, not previously investigated. The survey will be of two areas of the castle using Magnetometry, Resistivity and Ground Penetrating Radar (GPR)

The focus is on parts of the castle not previously explored by  excavations in the 1980s, especially around the northern ramparts. This area stretches from the Swillington Tower towards the Kings Tower, and includes several earthwork features which remain unidentified, or unconfirmed.  Geophysical investigation is likely to reveal several interesting features including the link wall between the curtain wall and the Swillington Tower, which is unique in that it was built outside the main castle defences.

A second area that we have very little information on is part of the castle known as the “service buildings”. This area has never been excavated and we have very little knowledge regarding the layout or function of this part of the castle. 

As yet it is unclear when the survey will be undertaken.

Raby, Co Durham:

Aerial View of Raby Castle copyright Raby Castle

The Trust will be co-funding the project which aims to improve the understanding of the castle in the medieval period, especially around 1400 in the decades immediately after the licence to crenellate, with a buildings survey and development of a 3D model.

Once a stronghold of the Neville family, it moved into the ownership of the Vane family in 1626 and has been much altered and modernised, especially in the Victorian period, into a palatial family home.  Large sections of the medieval castle survive intact, albeit intersected and extended with more recent architectural additions.

This project seeks to strip back the more recent layers, to make sense of the medieval castle. Our aim is to create a 3D visualisation of Raby Castle in around AD 1400, helping us to visualise and to understand (where possible) how it functioned before the later additions.

In addition to boosting our understanding of the castle, the plan is also to train up a team of volunteers in how to carry out a building survey.

The aim is to start the survey work in April. 

Shrewsbury, Shropshire:

Shrewsbury Motte Top copyright Nigel Baker

This is the third project the Trust has funded on this important castle of the Welsh Marches and is an excavation of the motte top. The first two excavations in the inner bailey discovered that the original inner bailey was a lot smaller than it is today with little room for any substantial buildings, especially the royal hall.

This leaves only the motte and the aim is to understand the structural sequence and assess the character and the status of the buildings there: specifically to identify the royal hall known to be present during the Middle Ages.

The excavation is due to take place in the second half of July.

Caerlaverock: Harbour Fieldwork

Thanks to funding from the Castle Studies Trust, Historic Environment Scotland are working with researchers Dr Richard Tipping and Dr Eileen Tisdall to understand the chronology and geography of extreme weather events in the high medieval period, and the effects they wrought on archaeological features that led to the abandonment of the old castle built in c.1229 in favour of the new built 200m away in c.1277. Here Richard Tipping gives an update on the fieldwork which too place last Saturday (2 October).

Subscribe to our quarterly newsletter

One of the great puzzles of old Caerlaverock is the so-called harbour (Image 1). It is south of the old castle, two metres lower, and just north of where we think the early medieval coastline was, so it’s difficult to think what else it could have been. But it’s never been independently dated, there are rumours that it was Roman, and there are knotty interpretative problems. One is that the floor of the harbour is at an altitude that would make it tricky to get more than rowing boats in and out in the Middle Ages; this is also a problem if the harbour was older. A second is that there is a fourth side at the southern end, which greatly restricts access. As Richard Tipping explains below:

The harbour has three metres of sand above bedrock. We don’t know how old the sand is. One idea is that it’s all very old – 8000-6000 years old. This would mean that the harbour was never deeper than it is now. Another idea is that the sand is of two periods, with an older bed covered by medieval sand: the same stuff that filled the moat of the Old Castle. And a third is that all three metres of sand are medieval in age. This would imply that the builders created a five metre deep harbour, which was then filled with sand as storm surges drove sediment onshore.


Dating of the sand is the answer. To this end, a team of eight (Richard Tipping and Eileen Tisdall from Stirling; Tim Kinnaird, Aayush Srivastava, Richard Bates and Laura Bates from St Andrews, and Morvern French and Steve Farrar from Historic Environment Scotland) assembled under gloomy skies and a more intimidating forecast to sample the sediment.

Here Richard Bates explains what they are going to do:

Richard Bates had a vibro-corer, a machine that went through three metres of sand as if it was butter: astonishingly impressive:

The three cores came out and were immediately wrapped in black plastic bags because sunlight, even that under grey clouds, cannot be allowed to shine on the samples. The reason for this bizarre behaviour is in how the sediment will be dated

Wrapping the sample

Tim and Aayush are specialists in optically stimulated luminescence (OSL) and infra-red stimulated luminescence (IRSL) dating. This is a kind-of accumulation clock. Over time, quartz and feldspar sand grains buried by sediment accumulate energy released from surrounding sediments at a constant rate. This energy is released if sunlight hits the sand, or under controlled laboratory conditions, when light at optical or infra-red wavelengths hits the sand. If the energy released can be measured, which is Tim’s and Aayush’s job, we can establish the age of the sand as Tim explains here:

The Castle Studies Trust grant will fund three OSL dates from the base of the sand, the middle, and towards the top. As soon as we learn the results, you will.

And the rain stayed away.

Caerlaverock and the impact of Medieval storm surges

As Drs Richard Tipping and Eileen Tisdall along with Dr Tim Kinnaird of St Andrews return to Caerlaverock to carry out their final piece of field work this Saturday (2 October), Richard Tipping discusses what has happened so far.

Background

Earlier blogs have described the fieldwork, over the summer, at the Old Castle at Caerlaverock in south west Scotland. We have been testing the idea that several very large storm surges impacted the castle, persuading the occupants to re-build, higher up and further inland. That fieldwork involved recording sediments in the moat (Figure 1) and surrounding ditches, confirming that these sediment traps are full of silt derived, we think, from storm surges pushing sediment from the coast, through the harbour and into the moat. We’re checking the origin of the silt from diatom analyses, which can define water salinity. But we hadn’t found evidence that these storm surges were destructive, impacting archaeological features. Now we think we have.

Setting

The ‘park pale’ is the name given to a ditched-&-banked enclosure that extends west from the harbour at the old castle for several hundred metres (Figure 1). It was constructed along a small cliff that marked the medieval coastline, separating mid-Holocene estuarine sediment, called ‘carse’ to its north and a series of very broad, parallel east-west trending ridges and basins constructed by medieval storm surges to its south (Tipping and Adams 2007).

Figure 1. Natural and archaeological features near the ‘park pale’ at Caerlaverock.

In Figure 1, a LiDAR image, Ridges 9 and 10, and Ridges 15 and 18 are seen. Between them, lagoon basins were trapped: Basins 8, 3 and 4 here. Some basins will be radiocarbon dated because peat formed when they were isolated from wave action. 

In detail (Figure 2) the ‘park pale’ is complicated. There is an inner bank to the east, with a crest around a metre higher than the ground to its south. This is lost at a 25m wide gap and cannot be traced further west. Instead, a second, lower outer bank continues north west to the New Castle Burn (Figure 1). The outer bank has, in places, an outer and inner ditch. Another, 4m wide gap may be what Brann (2004) thought was an entrance.

Tr 3 (ii) is the line of a 50m long sediment-stratigraphic transect of 24 hand-sunk boreholes from the ‘carse’ in the north, which the inner bank rests on, south across Basin 3 to the canalised Old Castle Burn. The transect was designed to test the idea that the 25m gap in the ‘pale’ is an erosional feature from storm surge impacts.

Figure 2. Features around the distinctive 25m wide gap in the ‘pale’

Stratigraphy

What Tr (ii) shows is that the low ground of Basin 3 is floored by bedrock less than a metre down. This is covered by well-sorted sand and then by poorly sorted coarse to very coarse sand and grit with common pebbles.This fills Basin 3, thickening shoreward. This is interpreted as a storm surge deposit, deposited in a high-energy marine environment. Boreholes on the inner bank, a metre higher than Basin 3, and 25m inland, also recorded thick gravelly sand, impenetrable at 90cm depth on the inner bank. This thins north but is still found 20m inland from the medieval coastline.

Narrative

There were at least two storm surge ridges formed before the events recorded in Basin 3. Basin 8 (Figure 1) was formed by the second storm surge, as yet undated. This created Ridges 9 and 10. These broad gravel ridges in turn protected the western ‘park pale’ from subsequent marine erosion (Figure 2). What is now the outer bank, with its associated ditches, probably represents the original boundary of the ‘pale’. The ‘pale’ pre-dates the storm surge event described here. It is shown by the sediment stratigraphy to be, broadly, medieval in age and, broadly, contemporary with the old castle.

Eastward, Ridges 9 and 10 merge with the ‘carse’ of the medieval coastline, leaving this part of the coast vulnerable to later storm surges. At this point, the outer bank of the ‘pale’ is lost. In its place are storm surge sediments. The ‘pale’ was eroded by the storm surge. This storm surge pushed at least 90cm of gravelly sand north onto the surface of the ‘carse’. The cliff may have been formed after this storm surge, by later erosional wave action. Gravelly sand was pushed or thrown 20m beyond the cliff. Waves also scoured the easily eroded ‘carse’, lowering the surface by around 0.5m, up to 100m inland.

Old Wick: Removing the Joist

On Wednesday and Thursday 22nd and 23rd of September, a team lead by Rachel Pickering of Historic Environment Scotland and Coralie Mills undertook to remove the remains of wooden joist from the keep at Old Wick Castle. The joist hole was 8 metres above ground level. If successfully removed the joist was then to be taken away for testing and hopefully provide a date for it and the castle. In a slightly different blog than usual here are three short videos looking at how the removal process went.

Testing time at Castle of Old Wick, Caithness

As the Old Wick project gets underway, the project lead Rachel Pickering of Historic Environment Scotland explains what they are trying to find out and how.

In the far northeast of mainland Scotland, on a narrow promontory, surrounded by cliffs on three sides, stand the ruins of Castle of Old Wick. The castle is one of Caithness’ most striking medieval sites due to its rugged location. But time has not been kind to the castle, and all that survives above ground is the stark stone skeleton of a once grand tower, within low-lying earthworks on the promontory behind. There are many unanswered questions about this castle, not least ‘when was it built?’.

Very little is known about the castle’s origin and development – there is limited documentary evidence relating to its earlier history and no diagnostic architectural features survive, making it very difficult to date. It was once thought to have been one of the earliest stone castles in Scotland, associated with Norse earls of Orkney and Caithness. However, more recently, scholars have questioned this, suggesting a 14th century date is much more likely for its construction.

One tantalising clue survives that may shed light on its construction history – a single fragment of timber within a joist socket of an upper floor. The image below shows these joist sockets which indicate the tower had timber floors throughout. The sole surviving timber is increasingly at risk of decay as it is exposed to the elements. Our aim is to remove the timber and assess it for dendrochronological analysis – or tree-ring dating, before conserving the remains. From this we may be able to get a scientific date to indicate when the castle was built. At the very least, such a date may provide an age and provenance for the timber joist which provides an insight into phases of the castle’s development.

Thanks to generous grant funding from the Castle Studies Trust, HES and specialist contractor Dr Coralie Mills of Dendrochronicle will be carrying out new research this autumn, with the hope of recovering dating evidence.

The timber is believed to be oak, making it suitable for dendrochronological analysis, though it is in a very fragile state. It will be accessed using a scaffold and very carefully removed and wrapped before being transported to the laboratory in Edinburgh for detailed examination. Its condition and suitability for dendrochronological analysis will then be assessed. If it is not possible to analyse the rings of the timber due to its condition, then an alternative method will be undertaken using radiocarbon ‘wiggle matching’. This would involve taking several samples for high precision radiocarbon dating, allowing for a more accurately calibrated radiocarbon date for the timber.  

We hope this research will shed light on the construction and development of Castle of Old Wick, by providing valuable scientific dating evidence. The project will also potentially support the on-going development of dendrochronological analysis within Scotland, as every new analysis can help to add to and refine existing tree-ring chronologies, which in turn supports future research.
