‘Sowing Seeds and Reaping Rewards’: relict plant studies at medieval castles

In 2020, the Castle Studies Trust funded Dr Karen Dempsey to undertake an innovative new line of research in castle studies, namely to explore the use of plants in castles in medieval Ireland. In this article, Karen explains what she and her colleague Dr Fiona MacGowan discovered.

Over the course of this Pandemic many people have a newfound or renewed appreciation for the green world that we live in. This might take material form by growing potted plants at home and if fortunate caring for a garden space of your own or somewhat less tangibly, the contemplation of changing seasons in your local park. The (anecdotal) health benefits we might feel from these activities are increasingly underscored by health professionals who assure us of the roles of green spaces in wellbeing. This connection is not a modern phenomenon – plants (and gardens) played a significant role in the diet, healthcare and spirituality of people living as part of castle households.

‘Sowing Seeds of Interdisciplinary Work’, the Castle Studies Trust funded project, showed how relict plants can deliver new insights into everyday life at medieval castles. Relict plants – understood to be the descendants of plants grown, cared for and used by (medieval) people – were identified through botanical surveys at four geographically diverse but culturally similar medieval castles: Adare, Co. Limerick, Castleroche, Co. Louth, Carbury, Co. Kildare and Castlecarra, Co. Mayo (as detailed in my previous blog post). As an initial step in researching relict plants, particular attention was paid to archaeophytes, those plants which arrived in Ireland pre-1500 CE. I believed that these plants may have participated in the various colonisation processes of the twelfth century. Their introduction could be linked to new gardening and other health practices especially those related to novel plant medicines which were emerging across Europe at this time but were perhaps previously unknown in Ireland.

Relict Plant Findings

Botanical surveys began during mid-2020 in the very wet months of June and July after a hot May.

Over the course of the survey eight archaeophytes were revealed (Table 1) as well as a range of rare and common native plants. You can read Dr MacGowan’s botanical report here. These findings are significant: four of the eight plants were historically recorded as present in medieval gardens. The plants – comfrey, mallow, milk thistle and hedge mustard – are widely recognised as having medicinal properties (Fig 1). They feature in medieval recipes, continued as part of the tradition of plant medicine captured in Culpepper’s Herbal of 1653 and some, like milk thistle, remain in use today (see Table 1).

Relict Plants in their Castle Contexts

Castleroche was the first site surveyed for our fieldwork. It is spectacularly situated on a locally significant rocky outcrop, framed to the north by the foothills of the Mourne Mountains (Fig 2). The castle has been long understood as a defensive site, believed to have been positioned as authoritative infrastructure to exercise territorial control. Its’ patron, Roesia de Verdun (d.1247) is renowned as the only historically attested woman to have founded a castle in thirteenth-century Ireland This castle while now in ruins was once a busy place with an associated village replete with a weekly market and annual fair. I considered this site to have great potential for relict plants given that historic sources noted the presence of ‘gardinia’ (gardens associated with castles) coupled with the high-status of its’ patron who had a considerable number of estates across England and France. These connections must have given her and her staff access to, and knowledge of, different cultural traditions including gardening and medicinal practices. We were delighted to identify three archaeophytes: Hemlock (Conium maculatum), Mallow (Malva sylvestris) and Milk thistle (Silybum marianum). Milk thistle is a particularly important identification, it is very rare in Ireland and Britain. For medieval people, it was culturally and symbolically tied to the Virgin Mary as well as understandings of fertility and motherhood (Fig 3). This allows us to reconsider the idea of Castleroche only as a frontier site; perhaps there was a diverse resident population for much longer than previously understood. Their health concerns may be represented by the continued occurrence of these plants. Exploring the botanical legacy of Castleroche adds further layers to the story of this complex site.

Figure 4 Carbury, Co. Kildare: a multiperiod castle complex comprises a motte, an early masonry focal building with later additions including an Elizabethan extension crowned with multisided cut stone chimneys

A less well-known castle but equally deserving of attention is the medieval settlement at Carbury (Fig 4). This multiperiod complex comprises an earthwork castle, a twelfth or very early thirteenth-century masonry castle with later additions including an Elizabethan extension and related gardens (Fig 5). Carbury is entangled with generations of nobles. It acted as a central node in shifting political allegiances and dynastic disputes within the territory of Leinster. The longevity in occupation of Carbury is interesting, it attests – at least in part – to its suitability as a residence. Is this reflected in the immediate castle landscape? Is there a possibility that the early-modern gardens here overlay medieval predecessors? Four archaeophytes were found at Carbury: Hemlock, Comfrey (Symphytum officinale), Hedge mustard (Sisymbrium officinale) and White stonecrop (Sedum album), three of which were adjacent to or within the masonry castle and the fourth – Comfrey – which was found within the hedgerow that forms the historically significant boundary to the castle landscape (Fig 6). These plants are not uncommon, but perhaps their relative ubiquity is reflected in their suitability for use within different plant medicine traditions. Comfrey is particularly notable, known as knitbone, it was widely used as a healing poultice for broken bones throughout medieval medical texts. Pharmacologically, this plant contains allantoin, which promotes the creation of new cells and healing of connective tissue. Relict plant studies at Carbury allows us to reflect on how this place was a home to many different generations of people who participated in caring roles (for plants and people) whilst also being a locus for political tensions.

With these exciting discoveries at both Castleroche and Carbury, we were very hopeful that the survey at Adare Castle would be equally rewarding. Adare was an important castle as the caput of the Geraldine family. Unlike the other sites, it has been subject to major study including detailed historical and archaeological investigation. Adare Castle was constructed on a pre-Norman power centre from which the castle emerged as a large D-shaped earthwork with a surrounding large ditch and river-fed moat (Fig 7). This later formed the inner ward, which was further enclosed by an external wall to the north-west with a single mural tower and a gatehouse to the south. The outer court is enclosed by masonry walling which is augmented by a ditch to the north and west. At Adare, the grounds are intensely managed, with manicured lawns and ongoing pesticide use (Fig 8). Unfortunately, this was particularly pronounced in the inner ward, the area I have suggested was likely to have contained an enclosed garden. Disappointingly, only one archaeophyte was identified: Weld (Reseda luteola). This dyeplant was predominantly used to give a bright colourfast yellow but also used medicinally to treat chest complaints. A number of neophytes – those plants whose introduction post-dates 1500 CE – were found in the associated areas surrounding the castle as detailed by Dr MacGowan. Species such as Himalayan pheasant berry (Leycesteria formosa) were identified, indicating that relict plants studies can also illuminate the afterlife of the castle when it  played a role as a romantic ruin in the eighteenth-century landscape of Adare Manor. This shows the potential for relict plants studies to add layers to castles stories across their life histories.

Figure 8 Adare Castle, inner ward subject to extensive pesticide use

The final site, Castlecarra, falls lower down the social hierarchy of medieval Ireland than the other three castles but it was still an important baronial residence (Fig 9). It is situated on the eastern shore of Lough Carra. The castle now comprises a large three-storey focal building set within a very compact enclosure which is a later, potentially fifteenth-century addition. The castle was constructed as one part of the c. 1236 Anglo-Norman territorial expansion into Connacht. This site, like the others, has a long history of occupation. An early-modern (sixteenth-century?) house was constructed c. 125m NE of the castle, and the surrounding landscape appears to have been remodelled to suit a new tradition of landscape gardening which included a ha-ha and tree-lined avenue of Hornbeams (Carpinus betulus) (Fig 10). Archaeophytes were not recorded at Castlecarra but numerous native species as well as neophytes were present. This absence is remarkable but perhaps native plants at Castlecarra served the castle household needs. For example, Purging buckthorn (Rhamnus catharticus) was identified. This plant is native but rare in Ireland, and it was used medicinally as a purgative, as the name suggests. The botanical profile of Castlecarra leads to further questions around the transmission and sharing of medicinal and plant knowledge.

Research, Heritage Futures and Reflection

One of this project’s aims was to test and refine the methodologies of relict plant studies for medieval castles. In Ireland there are currently 96 species recorded as archaeophytes (but with no established dates of introduction).  Despite the findings of some notable plants, the overall numbers of archaeophytes at the castle sites in ‘Sowing Seeds’ seemed low. Of course, our findings may have been constrained by single survey days, unseasonal weather as well as conservation and management issues – both present-day and historic. Future work is necessary. It is important that sites have the benefit of multiple visits across a wider seasonal survey period. Nevertheless, the baseline botanical surveys of this project will be of use for future research within and outside of castle studies. It has also revealed the need for a detailed survey of archaeobotanical evidence from excavations in Ireland to establish  as far as possible exact introduction dates for particular plants.

Including a wider range of plants and castles over a longer time span would provide comparative material with a greater capacity to capture change over time. Neophytes were noted in the botanical surveys but not part of the research agenda for ‘Sowing Seeds’. Their occurrence at castle sites may be revealing of expanding connections with sixteenth-century colonising and trading practices beyond Europe. Later medieval towerhouses are of particular interest as they are often situated within less managed and therefore within potentially better-preserved landscapes. But equally, native plants should also be included. For example, self-heal (prunella vulgaris) and pellitory-of-the-wall (Parietaria judaica) occur widely and were both used as medicinally. It would be of great interest to compare and contrast different plants at castles whether native, anciently introduced or more recent. Consideration too could be given to the afterlives of medieval castles as romantic ruins as indicated at Castlecarra and Adare. This would develop a wider appreciation of the long lives of medieval castles that continue in dialogue with contemporary communities as heritage today. Relict plant studies enable castle studies to participate in emerging conversation around green heritage and climate change.

‘Sowing Seeds’ was a novel project – both conceptually and methodologically – I wanted to find a way to explore potential ‘green identities’ of castle households. Accessing the relationships medieval people may have had with their environments (as we might term it today) offers a different way of telling stories about the medieval past whose narratives are often caught into concerns of power, authority or control. By including botanical surveys of relict plants in castle landscapes, we have expanded further the multidisciplinary approach of castles studies. We can show how stories of castles are richly textured: populated by many people and plants over the course of their lives and beyond into their afterlives as romantic ruins and archaeological monuments. Doing this for the first time meant engaging with new material and unfamiliar sources from archaeology, history, and medical knowledge to heritage and folklore. This wide-reaching research methodology is a core strength of this project. It enables a dialogue between different disciplines that are traditionally separate or rarely integrated. These findings are a beginning: they encourage new avenues of future research on castles households relating to human-plant relations, plant medicine and related concepts of care. The results also invite conversations with heritage agencies regarding site management and conservation practices of both biodiversity and past vegetation. Rather than offering conclusive findings, we have revealed tantalising hints and a vast array of potential new avenues in which to take this research.

Sowing Seeds of Interdisciplinary Work: Relict Plants at Medieval Castles

Thinking Green

Like medieval monasteries, castles had gardens. These could be places of rest, play and display as well as productive centres for (some of) the food to supply the castle household while also providing curative or medicinal plants. We know that in the Middle Ages, plants were highly valued for their culinary, fragrant and medicinal properties; and, they were considered to have mental and spiritual benefits. What do we know about the plant-life of the medieval castle and its green spaces?

Surviving architecture indicates that some of these spaces were enclosed with relatively high walls, often surmounted by a parapet or at least crenelated. Excavations tell us something about what plants were at castles but there is no certainty about what was grown in their gardens.1 Seeds can be tricky to identify in the archaeobotanical record from reasons as diverse as poor preservation to sampling issues. Beyond general mentions of gardens, medieval historians have noted references to bowers (arched trellis covered with vines or climbing plants) and possible water features as well as hawthorn hedging, roses and juniper trees.2 Many medieval manuscripts show luxurious images of trellising and water features in a verdant green dreamland (Fig. 1). I am not going to suggest that exact replica sites of mythical gardens existed but perhaps we can use these images as a reference point.

So, we know what gardens might have looked like and some of the things that may have been present. What then, do we know about gardening?3 Certain castles, such as Richmond, have latrines that empty into the garden space suggesting that medieval people were good at composting! (Fig. 2) But what about plant propagation and curation? What plants or flowers were grown? Or how?

Figure 2. ‘Cockpit’ Garden at Richmond Castle, latrine on eastern wall. Authors own.

Nurseries were established at monasteries across Europe in the later medieval period; one existed in London by at least the late thirteenth-century4 and at Kilmainhaim, Ireland during the early fourteenth century.5 Perhaps they also existed at castles? Some medieval manuscripts show images of plants in pots – isn’t that very interesting? (Fig. 3). So possibly plants in pots, like elite households, were on the move.6 If plants moved with their households what types were selected? Were they transplanted to grow in new locations? While extensive archaeological excavation might be able to answer these questions – what if we look at the evidence in front of us: the modern ecological landscape?

Might the modern landscapes of medieval castles give some clue to plants of the past? The study of relict plants – those that survive from the past – involves the examination of modern landscapes for the presence of plants that may have been deliberately planted and cared for by people in the past. An ecological survey of Welsh castles completed in 1994 by Ann Connolly noted that there were clusters of plants with known medicinal uses present at castle sites but notably absent from suitable surrounding terrain.7 This included wild sage (Salvia verbenaca) at Montgomrery and wild rocket (Reseda luteola), as well as henbane (Hyoscyamus niger) at Rhuddlan. The implication is that these plants were deliberately planted at these sites for their medicinal use.

Pioneering work has been completed on relict plants in from medieval monastic gardens in Norway8 and Iceland.9 Fiona MacGowan, working in Ireland noted the presence of yellow wallflowers (Erysimum cheiri) at the windows of the main focal building at Lea Castle, Co. Laois (2014; Fig 4). These are non-native to Ireland and were thought to be frame the windows and waft in good smells. Relict plant studies, as part of wider analyses, is becoming established as a novel way to gain insights into past communities’ growing or cultivation practices as well as potential medicinal and dietary concerns.

‘Sowing the Seeds of Interdisciplinary Work’, the project funded by the Castle Studies Trust sets out to build on this work, and understand if surviving plants at medieval castles which were possibly planted, grown, cared for and used by medieval people can further inform us of medieval lived experiences in the garden and possibly with gardening. Ecological surveys will be carried out at four geographically distant but culturally similar medieval castles sites with diverse landscapes: Adare. Co. Limerick, Castleroache, Co. Louth, Mocollop Castle, Co Waterford and Castlecarra, Co. Mayo (Figs 4-7).

From the selected sites, only Adare has been subject to archaeological investigation and therefore has an associated archaeobotanical report to be analysed.10 Castlecarra is surrounded by woodland which has the potential to be ancient; it is included in the Lough Mask and Lough Carra Special Area of Conservation (Site code 001774). It will be part of the survey. All four have associated settlements and a variety of religious houses from parish churches to abbeys. At Mocollop and Castle Carra these spaces will also be surveyed owing to their relatively undisturbed surrounding landscapes. They will provide an interesting set of comparative sites.

Working with Dr Fiona MacGowan, an ecologist who has a passion for the medieval, we will carry-out the ecological surveys over the late summer (hopefully). Once compiled the ecological reports will be used to expand our knowledge of what plants may have been used or grown at Irish medieval castles by contextualising the results within appropriate historical and folkloric traditions. These findings will be analysed together with of archaeological, historical and architectural details of the four castles sites. We are sure that the results will demonstrate the potential of relict plants studies to enrich our understanding of the ‘green’ lives of people in the past.

A Large and Eclectic Crop of Fascinating Applications for the Castle Studies Trust to Consider

The deadline for grant applications passed on 30th November. We’re going through the various projects now. Altogether the 13 projects, coming from England, Ireland, and Scotland are asking for over £88,000. They cover not only a wide period of history but also a wide range of topics. In a little more detail, here are the applications we’ve received:

Bamburgh, Northumberland

Hoghton, Lancashire

The aim of the project to continue the work the CST funded in 2019 with excavations and building survey. Further excavations will try and understand the purpose of the structures found in the 2019 excavation season and if they were related to the original great tower.

Holme Pierpont, Nottinghamshire

To build up an understanding of this late medieval great house, never previously researched. The work will include a mixture of desk research, building survey and geophysical survey of the parkland surrounding it. The house is the most complete of the three late medieval brick-built houses in Nottinghamshire.

Lincoln, Lincolnshire

To develop a reconstruction drawing of the castle as it would have appeared in the second half of the 12th century. Lincoln Castle was founded by William the Conqueror in the late 11th century.

Shrewsbury, Shropshire

To fund a second year of excavation, this time to understand the rampart of the inner bailey. The geophysical survey carried out in the 2019 suggested there could be remains of buildings there, possibly even a late Saxon church. Shrewsbury was a very important border castle up until the 13th century and frequently used as a base for English raids into Wales.

Sowing the Seeds

The aim of the project is to understand the military organisation of the northern part of Wessex (Wiltshire and West Oxfordshire) from the transition from Saxon to Norman rule between the 9th and 12th centuries. The work will involve documentary research, landscape and place name surveys. Sites examined will include Castle Combe, Cricklade and Silbury Hill.

The Wirk, Orkney

Rousay - The Wirk

Could the Wirk be a Norse castle? Based on the island of Rousay, this stone tower is situated close to the old parish church and recently discovered Norse Hall. However, no one knows what this tower was used for or even when it was built. The work would involve a geophysical survey of the surrounding area as well as two trial trenches to try and find dating evidence.
