Dutch Transcription and Translation December 2025 Update: Interpreting SP9/99

In their latest update Drs Paul Pattinson and Esther van Raamsdonk look at how far they have progressed with the transcription and translation of the Seventeenth Century survey of fortifications in southern England, revealing some pleasant surprises that have awaited them.

In our last update on Transcribing and Translating SP9/99: A Seventeenth-Century Dutch Survey of 22 English Castles and Fortifications, we concentrated on just that, the challenging process of transcription and translation of a difficult Dutch manuscript that uses unorthodox words (whose meaning is sometimes unknown), a note-like format, and a complete lack of punctuation. That process is now essentially complete, bar a few words that may be technical terms, and about which we are consulting with fortification experts in the Netherlands. However, we can now begin to interpret the manuscript and what it can tell us about the coastal artillery castles and bulwarks along the south-east and south coasts of England in the early seventeenth century.

After looking briefly at the whole manuscript of 23 folios (46 pages), we can now say that there are details of at least 29 fortifications, not just 23, and that may not be the final number. In due course we hope to establish a complete list. For the time being, the work for which we were generously grant-aided by the CST focussed on 9 folios covering 6 artillery castles, all of which were built or modified during the early stages of the ‘device’ programme of Henry VIII, between 1539 and 1541. We selected these as a suitable sample of the manuscript because historically they formed a discrete group in the jurisdiction of and under the command of the Lord Warden of the Cinque Ports: they are the castles at Sandown, Deal, Walmer, Dover, Sandgate and Camber.

Even though our unknown Dutch engineer was clearly in a hurry with his survey, as we reported last time, his work is accurate. For most sites there is usually a main plan taking up one face of a folio – a detailed and well-proportioned sketch with copious annotations that include measurements and notes on features of interest, sometimes including room use, and often pointing out defects requiring attention. In rare cases a room is named, notably ‘The Queen’s Room’ at Sandgate, a lovely, early reference to a tradition recording Elizabeth I’s stay at the castle in 1572. Sometimes, room functions are specified e.g. the porter’s lodge at Camber, giving valuable insight to the daily workings of a castle.

As well as a main drawing, the engineer also made smaller sketch plans and elevations to show details e.g. an elevation of the cupola at the centre of the roof at Deal Castle, noting also its use as both a gunpowder store and a sea mark; or a plan of a double-splayed gun embrasure at Walmer Castle. Typically, the particulars of each site are further noted in a separate block of text taking up another side of a folio, sometimes also incorporating small sketches. This text tends to summarise defects and requirements, so does not provide a full picture of the castle, but rather concentrates on repairs needed and remedies.

However, there is one atypical folio that mentions two known individuals. One is the relatively well-known master gunner at Dover Castle, William Eldred, notable for his authorship of The Gunners Glasse, a treatise on gunnery published in 1646. The other was a Mr Griffiths, secretary to Edward, Lord Zouche, who was Lord Warden of the Cinque Ports between 1615 and 1625. We are presently exploring them both in the State Papers at the National Archives and in other documents at the British Library and we are confident – and excited – that we will be able to tie down the date of the survey to the year.

The translation of three other folios for Dover Castle represents a real step forward in understanding that castle during this otherwise hazy period in its history. The manuscript names and provides details of eight mural towers, two gates and three other buildings explored by the engineer, most of which we can relate to those surviving today, possibly the earliest evidence we have for named towers in the castle: a few of the names are previously unknown. There are three sketches of tower plans, which should enable their identification: one is certainly Fitzwilliam Gate. Many of the Dover Castle towers needed significant repairs, for which the engineer estimated costs. The Dover folios also record two forts defending the harbour and anchorage. The first is Moats Bulwark, the battery at the base of the cliff below the castle, just above the beach, and the small angle-bastioned fort guarding the western harbour, Archcliffe Fort.

Only recently, we have begun to look closely at another survey, long thought to be broadly contemporary, carried out in 1623 by the Board of Ordnance at the request of James I and his Privy Council. Our initial work on this, comparing entries for the same sites, suggests that the two surveys may be closely related and we look forward to providing another update here, when we have fully explored that intriguing possibility.

A large and varied crop of fascinating applications asking for a record amount of over £170,000 for the Castle Studies Trust to consider

The deadline for grant applications passed on 1 December. We’re going through the various projects now. Altogether the 21 projects (the most we have received since 2014), coming from all over the UK and Ireland, are asking for a record amount of over £170,000. They cover not only a wide period of history but also a broad range of topics.

In a little more detail, here are the applications we’ve received:

Bodiam, West Sussex: Co-funding the third season of the excavations of the Bodiam 100 project at the fourteenth century castle with the aim of understanding more about the castle in its broader landscape and chronology. The request is to fund post-excavation costs, scientific dating and assessment of samples and the costs of a weekend event focusing on pilgrim badges to highlight the discovery and significance of the late 14th century badge found in the castle moat during investigations in the 1970s

Buittle, Dumfries & Galloway: Co-fund a geophysical survey of the motte of the castle. This site, once the home of two Scottish kings and closely associated with some of the leading figures and events in the Scotland of the 13th and 14th centuries, may be one of the earliest Mottes with a stone structure.

Cainhoe, Bedfordshire: Geophysical survey of the remaining part of the site not covered in 2022, which focused on the fortified manor section. The survey will look at the earlier motte and bailey castle which seems to have been abandoned by the late thirteenth century.

Carew, Pembrokeshire: To create new interpretive materials for Carew Castle that translate existing historical, architectural and archaeological research into accessible easy read signage.

Cockermouth, Cumbria: Cockermouth Castle is an extensively surviving major multi-phase northern fortress whose evolutionary history has never been subject to systematic or formal assessment.  The proposed project will focus upon developing a detailed understanding of the physical fabric of the castle’s inner ward structures with a view to mapping their evolution, and to provide contextualization by relating the major building periods to the site’s known history and occupancy, and in terms of the broader evolution of castle architecture.

Dunster, Somerset: Photogrammetry survey and analysis of the castle to understand the different phasing of the castle which dates to shortly after the Norman Conquest and has been much altered since.

Durham Castle, County Durham: Investigating the Twelfth-Century Entranceway of Durham Castle. The aim of the project is to utilise digital archaeological techniques to create high-resolution images and models of the twelfth-century archway into Durham Castle’s North Range, enabling detailed investigation of the architectural features.

Ellesmere, Shropshire: Geophysical survey of the large motte and bailey castle in Shropshire which, prior to June 2024, had never been surveyed before when the large motte was surveyed by GPR which revealed possible buildings. The resistivity and magnetometry surveys would confirm that, as well as survey the rest of the site which played an active part in the Marcher disputes in the reign of Henry III.

Fyvie, Aberdeenshire: The project aims to create new interpretation drawings to showcase key stages in the architectural development of the castle, which dates to the thirteenth century, and share these as part of outreach and engagement.

Lesser-known Essex Castles: The project aims to process and interpret LIDAR data relating to 23 less well-known Essex Castle sites such as at Chipping Ongar and Canfield. These castles were selected from the data within the Essex Historic Environment Record (EHER) as having very little, if any, previous archaeological investigation.

Little Beblowe, Northumberland: Excavation of the remains of the Henrician fortification, the first purpose-built fortification on Lindesfarne. The fort was built in the 1540s and has never been excavated. With much of the fort already lost to coastal erosion, this is potentially one of the last opportunities to excavate the site and see if the various plans of the fort match what is there.

Pontefract, Yorkshire: Digital reconstruction of the gatehouse of this one-time royal castle based on the 2019 excavations and previous studies showing its original structure and later adaptations.

Poulton Hall, The Wirral: A geophysical survey around the current hall to see if there are any indications of a possible castle. There have been numerous finds by metal detectorists indicating a medieval past for the area and historical sources indicate the site was high status  throughout the middle ages.

Newcastle, Northumberland: To co-fund the publication of the report of the excavations of Newcastle Castle, one of the major royal castles in the North East of England, which took place over 20 years between 1974-95. The funds will be for synthesising all the different excavations, updating specialist reports and preparing relevant plans and illustrations.

Ruthin, Denbighshire: Co-funding a structural survey and analysis of the great gatehouse of this formidable thirteenth century baronial castle that was a key part of Edward I’s strategy to secure the conquest of Wales.

Sauchie Tower, Clackmannanshire: Co-fund the first ever full structural survey of this early fifteenth century tower built by Sir James Schaew [check spelling]. Exceptional among the four surviving mediaeval towers in the county for having had very little alteration, thus preserving its structural integrity.

Sudeley Castle, Gloucestershire: Dating (via tree-ring dating) and recording with 3D imaging the original roofs of Sudeley Castles Outer Courtyard Ranges. The castle site dates to the anarchy but the castle was rebuilt in the fifteenth century by Lord Sudeley.

Temple House, Co. Sligo, Ireland : To co-fund the geophysical and LiDAR surveys of the site of this castle which was a preceptory (administrative centre) for the Knights Templar in Ireland. Historians have long recognized Templehouse as an example of the far-reaching influence of the Knights Templar in Western Europe. However, no scholarly research and no extensive archaeological work has been published on the site, besides a 2016 topographical survey

Tor, Highlands: Co-fund a LiDAR survey to try to locate earlier structures than the current remains of a C16 tower house. The site is thought to date to the early medieval period and was mentioned as the major site of Banquo of Macbeth fame.

Walton, Suffolk: Marine geophysical survey of the castle which collapsed into the North Sea in the eighteenth century. Originally a Roman Saxon Shore fort, it was later converted into a Norman castle by one of the Bigod earls and then destroyed by Henry II after the 1173-4 rebellion.
