A Dutch survey of English Castles and Fortification in the seventeenth century

The Castle Studies Trust has awarded a research grant to Dr Esther van Raamsdonk (University of Utrecht, Netherlands) and Paul Pattison (English Heritage) to work on an early 17th-century manuscript from the National Archives, concerning fortifications and castles on the south coast of England.

The manuscript was discovered over 40 years ago by Charles Trollope, following which, the late John Kenyon published a preliminary assessment (Fort vol 11, 1983, pp 35-56), showing that it related to a survey of several coastal fortifications along the south coast of England, mainly those that originated in Henry VIII’s castle building programme in the 1540s. However, the manuscript is in Dutch, so as Kenyon rightly says: ‘translation of the Dutch is required to assess the document’s full significance and to possibly produce a more exact date than I am able to postulate at this moment’ (p. 37). His article examines some of the plans in the document, but there is no engagement with the Dutch text, which is more than 50% of the document. No transcriptions or translations have therefore been made before.

The manuscript seems to be a surveyor’s on-site notebook, comprising fairly accurate and proportioned sketch plans. These beautiful drawings show a highly-skilled engineer at work, and one with a talent for exact survey drawings. These are supported by keyed notes and more detailed explanatory text. It covers most of the main fortifications and castles along the south coast, from Sandown Castle near Deal in Kent to Pendennis Castle at Falmouth in Cornwall.

Paul came across the manuscript several years ago and recently, prior to writing a new guidebook for Yarmouth Castle, Isle of Wight, looked for a palaeographer to transcribe and translate the pages for Yarmouth – enter Esther. Paul is a historic fortifications specialist, and his job is to help to make sense of the translation, as the conversion to English is not always obvious: there are many military and technical terms and sometimes the meaning is not immediately apparent. However, the sketched plans are annotated and keyed, which should help in understanding specific parts of each fortification. Esther is an expert palaeographer, having taught early modern English palaeography courses for some years, and scholar of 17th-century Anglo-Dutch relations. The grant is towards her costs of transcribing and translating the text and notes. It is not an easy task. The hand is a difficult one and several pages are faded. The Dutch engineer spent some time in England and the result is a hybrid language, a phonetic (for Dutch readers) spelling of English words. The document also functioned as a shorthand for the author, using non-standard abbreviations, idioms, and little drawings. The exercise is therefore not of a straight-forward transcription but requires quite a bit of puzzling.

As mentioned, we used the Yarmouth example to see what information we could gather from the manuscript. From this test case we know that the surveyor was commenting on condition and making recommendations for repairs and changes. Because of the detailed map and key, we could pinpoint the function of some rooms that were hitherto unknown. We look forward to see what further secrets the document will reveal about the other buildings.

The funding will enable us to examine a sample of the manuscript covering several sites in the Cinque Ports area of jurisdiction – Sandown, Deal, Walmer, Dover, Sandgate and possibly Camber. All of these are well known to Paul, and it is hoped that significant details about the condition of each castle or fortification will be forthcoming, for comparison with other contemporary accounts in English, to see and understand where this survey fits and whether or not it resulted in any repairs or additions on each site. John Kenyon thought it might date to the 1620s: we would like to try and confirm that, or otherwise, by comparison with earlier and later surveys, and to establish the political context for its commissioning. This will lead to at least one provenance article. The transcriptions (some of which will be published) will also provide a very valuable snapshot of the south coast fortifications 80 years or so after their creation, and form a test for the usefulness of going further and transcribing the whole manuscript. There is an exciting journey ahead.

Castle Studies Trust Awards a Record Amount in Grants

The Castle Studies Trust is delighted to announce the award of five grants, totalling a record amount of £42,000, to a wide range of projects with different types of research. The amount means that since our foundation we will have given over £300,000 to castle research projects – a landmark to celebrate.

The five projects we will be funding are:

Canterbury Castle Keep copyright geograph.co.uk

Canterbury, Kent: To create an interactive digital model of the castle’s keep. The keep is one of the largest surviving from early Norman England dating to the late eleventh / early twelfth century. Now much ruined and inaccessible to visitors due to instability, the project will use the findings of previous archaeological research to create an interactive model. Work will start in March and be completed within ten months.

Clavering Castle platform copyright Simon Coxall

Clavering, Essex: To fund an excavation to help understand the development of the site which was occupied for over 600 years and which could be one of the very few pre-conquest castles in the UK. The excavation will build on the extensive survey work carried out by the local group of the site. They are planning to do the excavations in June.

Crookston Castle copyright Friends of Crookston

Crookston, Glasgow: A community-led geophysical survey, using multiple techniques, through which the Friends of Crookston Castle in conjunction with HES hope to learn more about Glasgow’s only castle. While the standing remains are believed to date from the early fifteenth century, it is believed that the castle dates back to the twelfth century. The group hopes to discover evidence of that earlier history and whether it was based on an earlier Iron Age hillfort. They plan to do the survey in early August.

Knepp Castle copyright Richard Nevell

Knepp, West Sussex: An excavation building on a geophysical survey to better understand the site’s development and its relationship to the local area of this important baronial centre thought to be built by the de Braose family. The first documentary evidence is from 1210 when it was under royal control, documenting repairs, while the geophysical survey shows activity that pre-dates the extant stone tower. Excavations are planned for late July/ early August 2025.

A large and varied crop of fascinating applications asking for over £84,000 for the Castle Studies Trust to consider

The deadline for grant applications passed on 29 November. We’re going through the various projects now. Altogether the 13 projects, coming from all over Britain, are asking for over £84,000. They cover not only a wide period of history but also a broad range of topics.

We will not be able to fund as many of these projects as we would like. To help us fund as many of these projects as possible please donate here:

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

Cainhoe, Bedfordshire: Through various forms of media such as reconstruction drawings, models and generative AI video and prints, the Greensand Trust aims to provide visitors and educational groups with a better understanding of what this motte and bailey castle looked like, the lived experience there and why it is significant.

Canterbury, Kent: To recreate an interactive digital model of the castle’s keep. The keep is one of the largest surviving from early Norman England dating to the late eleventh / early twelfth century. Now much ruined and not accessible to visitors due to instability the digital reconstruction will use the findings of previous archaeological research to create an interactive model.

Castle Sinclair Girnigoe, Caithness: The castle was the principal seat of the Sinclair Earls of Caithness and was built between the fourteenth and fifteenth centuries. The application is to help publish the results of the archaeological research carried out during the emergency stabilisation of the site between 2002-2011. The grant will be to fund both ceramic and clay pipe analysis as well as some illustrations.

Chester, Cheshire: To create reconstructions of the inner and outer wards of Chester Castle as it may have looked in its heyday to add to the one currently being prepared on the Agricola Tower. Chester was one of the major castles of the Welsh Marches and was the base for Edward I’s campaigns in Wales.

Clavering, Essex: To fund an excavation to help understand the development of the site which was occupied for over 600 years and which could be one of the few pre-conquest castles in the UK. The excavation will build on the extensive survey work carried out by the local group of the site.

Cockermouth, Cumbria: Dating from the mid twelfth century this large northern baronial fortress has seen many periods of development but its evolutionary history has never been subject to systematic or formal assessment. The project will focus upon developing a detailed understanding of the physical fabric of the castle’s superstructure.

Cooling, Kent: Co-funding the creation of a model of Cooling Castle gatehouse. The castle gatehouse is scheduled at Grade 1 by Historic England underlining its importance. The Gatehouse was constructed by Thomas Crump on behalf of Sir John de Cobham in the fourteenth century. The design is interesting in that the towers are horseshoe shaped with no apparent back to them and were one of the first places to incorporate gun loops.

Crookston, Glasgow: A community-led geophysical survey, using multiple techniques, through which the Friends of Crookston Castle in conjunction with HES hope to learn more about Glasgow’s only castle. While the standing remains are believed to date from the early fifteenth century, it is believed that the castle dates back to the twelfth century. The group hopes to discover evidence of that earlier history and whether it was based on an earlier Iron Age hill fort.

Dundonald, Ayrshire: To fund a building survey of what is thought to be primarily the late fourteenth century remains of this baronial castle and perhaps reveal any evidence of the early thirteenth century castle. In addition the grant will help fund community outreach to explain the results.

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.

Knepp, West Sussex: An excavation building on a geophysical survey to better understand the site’s development and its relationship to the local area of this important baronial centre thought to be built by the de Braose family. The first documentary evidence is from 1210 when it was under royal control, documenting repairs, while the geophysical survey shows activity that pre-dates the extant stone tower.

Picton, Pembrokshire: To create a detailed reconstruction of the castle as it was first built in the early fourteenth century. This will be largely based on the detailed survey work the Trust funded  in 2023.

Translation of C17 Dutch Engineer’s Survey of English castles and fortifications: A joint project between Dutch academic Dr Esther Raamsdonk and English Heritage to do a sample translation of  five of the 22 castles and fortifications  surveyed in a document called SP 9/99,  an early seventeenth-century manuscript of a Dutch surveyor’s examination of the sites, held by the National Archives in Kew.  The sample will include Dover, Walmer and Deal. The document is filled with detailed drawings and maps of these fortifications with often lengthy descriptions of their condition.
