West Midlands Regional Research Framework for Archaeology, Seminar 5: Hurst 1 Medieval industry in the west Midlands Derek Hurst Worcestershire Historic Environment and Archaeological Service dhurst@worcestershire.gov.uk Summary Recent archaeological fieldwork has clearly uncovered much new material of medieval date, and a wide range of industrial activities are represented. In many cases this is the first occasion that evidence for a particular industry has come to light, and even the limited scientific analysis that has been undertaken has provided fresh insights into the processes being carried out. However, there are still major regional industries for which little buried archaeological evidence has been found, even when the industries should have left copious waste products. In some cases even industries associated with large-scale earthwork remains (eg stone quarrying) have not been adequately investigated in the field. Clearly there is a need for more and targeted fieldwork, as well as synthesis of data from sites already known. The application of historical evidence is not consistent, and the opportunities that this offers to provide greater insight into the past have yet to be fully realised. Introduction Knowledge of the material remains of the medieval period has moved on apace in more recent years where excavation in particular has produced large quantities of new data, some relating to industrial activity. There has, however, been little opportunity to synthesis these data, and much of the evidence remains rather scattered and largely inaccessible due to tardiness in publication or to its being confined to grey literature. As a result much of the following is based more on data held in SMR’s rather than on published reports, as this was certainly the most accessible data source for any rapid overview survey. The west Midlands is a region of great mineral diversity, as well as having important resources of fuel (both firewood and coal) in the medieval period. It is, of course, well known that in the post-medieval period the region became a major centre for industrial production of national and international significance. However, there is some evidence to suggest that, in the preceding medieval period, there had also been a strong industrial presence, at least in terms of metalworking especially in the central part of the region and taking in, for instance, north Worcestershire. The towns It is clear that many major industries in towns would not be likely to leave much trace in situ (for instance weaving, and cloth making generally). Those industries that show up best are of course the ones that involved structures being set into the ground. This would include tanning, for which examples are known at Warwick, Birmingham and possibly Hereford, or activities such as bell founding where large quantities of distinctive waste were produced (eg at Worcester and Ludlow). Other industries that have shown up in urban settlements are miscellaneous metal working (Birmingham, Dudley), floor tile manufacture (a kiln, for instance, has been recently discovered in West Midlands Regional Research Framework for Archaeology, Seminar 5: Hurst 2 Worcester), pottery making (Warwick), flax retting (Leominster), and possibly dyeing (possibly Hereford; Shoesmith 1982). Droitwich was an unusually specialised industrial centre, which supplied salt over a wide area, and which by the medieval period, had already been in continuous production for over 1500 years (Woodiwiss 1992). Recent excavations have revealed much about the structures and equipment associated with the salt production, including the site of the main brine well at Upwich (Hurst 1997). Both structural and artefactual remains were preserved by waterlogging, and the saline conditions preserved fragile vegetable matter that even in waterlogged conditions would not normally be expected to survive. Documentary evidence for the medieval salt making has also survived in great detail, and the industry has been well served by historical research (Berry 1957), which has unravelled the curious way in which the industry functioned. More documentary research, such as by Dyer (forthcoming), will continue to provide a more vivid picture of the industry. In some towns specific plots have been proven to be associated with specific industrial activities. For instance, just within the south gate of Worcester (Sidbury; Carver 1980), bronze metalworkers had established their workshops. Craftsmen sometimes congregated together, and whole streets could be involved in a particular craft or trade, which was usually reflected in street names. Sometimes, however, excavation in towns has been quite narrowly directed. There have been occasions where efforts were concentrated on the fronts of burgage plots with the intention of recording building remains, while, in contrast, the back-plots were not explored with as much care where evidence for industry might be particularly expected to have accumulated. An example of this would be parts of Droitwich as excavated in the 1970s (Hughes and Hunt 1992). The countryside Many types of industry are still little represented by archaeological evidence, even when they are well attested by medieval documentary evidence, and many of these were based in the countryside. For instance, local pottery production is often not precisely located on the ground, though the main source areas have now often been defined through petrological study of the pottery. Even major pottery industries have proved elusive on the ground (eg the Hanley potters of Worcestershire who produced the Malvernian wares over at least 400 years). Here a campaign of fieldwalking and geophysical survey over several years, in a collaboration with local enthusiasts, finally located and sampled a 15th-16th pottery kiln structure (Hurst 1994). This produced a surprising amount of partially fired pottery, which subsequently enabled scientific analysis to shed some light on the glazing techniques that were in use (Hurst and Freestone 1996). Another approach has been to compare documentary evidence for potters (a term that some have seen as only applicable to the producers of metal vessels) with the pattern of industries distinguished by archaeological methods, and this has indicated that many small-scale rural potters over a large area might have been working in a common tradition (Hurst 1990). Even where such an industry has been more evident in a later period, its medieval antecedents, though strongly suspected, have been difficult to prove. A case in point may be the Deerfold/Lingen industry of north Herefordshire which is established as a West Midlands Regional Research Framework for Archaeology, Seminar 5: Hurst 3 17th century industry, whilst its origins are less well understood (Hurst 2002). The regional importance of medieval pottery from the Stoke area is still to be appreciated as a scientific fact, though it is strongly suspected by those working in this field. The related brick and roof tile industries were also a feature of the medieval period. These must have been considerable industries, and they seem to have been based in mainly rural contexts, with their products often conveyed (as in the case of pottery) over long distances. The recent discovery of a tile kiln close to the city of Worcester will no doubt reveal much more about how this industry was organised (Miller pers comm). The production of floor tiles required similar kilns, and examples have been discovered typically within the grounds of conventual churches (eg Malvern Priory) or parish churches (St Mary’s, Droitwich). In the medieval period it is likely that the division between agriculture and industry was not as sharply defined as by the modern-day observer. Crafts, such as pottery making and iron production were often undertaken at scattered sites in rural isolation, in these cases often in a woodland setting (Birrell 1969). They were often undertaken in combination with farming, and it is even possible that some farmers were erstwhile potters who had used their profits to buy land and then financed others in their potting. Factors such as these may account for some of the difficulty in locating the production areas for industries which were important enough to be of significance for the local and regional economy. Unfortunately even where some pottery making sites have been revealed, for instance at Weobley in Herefordshire, and Deritend in Birmingham, these sites, despite the local and regional significance of the material, remain very imperfectly understood. Certain industries may also be seen as having a particular association with the west Midlands. One such would be the salt industry in Droitwich (see above), but others would be the iron industries of south-east Herefordshire (Forest of Dean), north Staffordshire, and the Dudley area, which were also notable regional industries at this time. The latter has a great significance as a direct precursor to the ‘Black Country’. However, in most cases the ‘archaeological’ evidence is largely documentary in nature. It is evident that some of the more innovative of these industries were under the control of Abbeys, for instance some of the bloomeries of Herefordshire were exploited by the Cistercian monks of Tintern. Abbeys in general stimulated industrial activity as they demanded building materials of a high standard (eg ceramic or stone roof tiles, decorated ceramic floor tiles, and metal fittings), but they also often became the centres of industry in themselves, for the purpose of exploiting their granges and of generating income. For instance Bordesley Abbey seems to have had both agribusiness and industrial enterprises under way (wool (Hilton 1966, 80-2) and iron founding (Astill 1993) respectively). One of the most outstanding areas where data has not been collected is the identification of stone quarry sites. Shropshire has been fortunate that its building stone has attracted study, and this has led to the identification of relevant quarries (Scard 1990). Other parts of the region are far behind on this subject. Here odd quarries have been recorded, but there is no overall understanding of this industry, which had associations with the more impressive buildings that were raised in the medieval Midlands. Mineral quarrying was also widely practised, with iron ore, for instance, being mined in the Clee Hills of Shropshire, and lead and silver being West Midlands Regional Research Framework for Archaeology, Seminar 5: Hurst 4 extracted in south Shropshire, and iron ore and coal in Staffordshire. Coal was also available in north Worcestershire and south Shropshire, but the early exploitation of all these deposits is still largely unknown. Though Dyer (forthcoming) has recently demonstrated that coal was used in the Droitwich medieval salt industry from an earlier date than has been previously thought. Many other smaller-scale rural industries, for instance treen manufacture, flax retting and basket weaving, remain under-represented by archaeological evidence, but also little mentioned in documentary sources. Any archaeological discovery relating to these processes would, therefore, be proportionately more valuable. Agricultural production should not be omitted from this ‘industrial’ scene. Corn growing was a major feature of the Severn valley, but, more distinctively, wool production was of first importance, particularly for the west (ie in south Shropshire and in north Herefordshire), and in the extreme south of our region (south Worcestershire and south Warwickshire). The wool from these areas was some of the most valuable produced in this country at a time when English wool was largely exported to north-west Europe, and was the main national export commodity in terms of value in this period. Little archaeological trace of this is understood to survive, and as a result it has not coloured our archaeological appreciation of the past history of these areas. However, some evidence may in fact already be obvious, for one indicator may be the presence of medieval fulling mills (eg at Broadwas and Childswickham in Worcestershire; Ludlow, Ludford, and Corve in Shropshire) suggesting that at least some of this most valuable of wools was being turned into textile more locally. Use of documentary evidence For the medieval period the possibility of documentary sources providing much more information about the past makes for a much more complete picture. This interplay of sources makes the medieval period particularly attractive for those that like to keep their archaeological feet on the ground. Both types of evidence have their particular, and sometimes surprising, contributions to make. For instance, the earliest documentary dates for processes can sometimes turn out to be quite misleading, such as when the water-powered metal working mill at Bordesley turned out to predate any documentary evidence for this process by over a century (Astill 1993, 303). Though recent archaeological fieldwork may have uncovered a great deal of medieval remains of all types, the integration of this data with relevant historical sources has often not been attempted, as the archaeological data is too fragmentary and limited. However, much archaeological reporting is too orientated towards description and categorisation of the material culture of a period for which the wealth of medieval documentation can do much to help provide a more rounded and developed view of the past, that goes beyond the objects or remains that the archaeologist has uncovered. An agenda for the future? The following are some general points about current professional practices, and some of the strategies which may benefit research on medieval industry, if more consistently developed, and applied in future: West Midlands Regional Research Framework for Archaeology, Seminar 5: Hurst 5 It is still very difficult to establish scientific programmes of research for investigating materials such as pottery, in order to establish trade routes and areas of economic connectivity. Period specialist groups could perhaps usefully play a bigger role in promoting local and regional research projects. Sites are still proving elusive, since research is not generally possible within the practice of archaeology as a development-led process. More pro-active fieldwork, including especially fieldwalking and extensive geophysics, is still needed to chart the extents of some of the more major industries such as pottery making. Where site locations are unknown, and where sites are possibly being inappropriately managed as a result, then damage for instance by ploughing is extremely likely. This is a general problem in archaeology, whatever the period (Darvill and Fulton 1998). The industries that produced much of the material culture of the medieval past are not known in terms of their technological development, nor is their impact on their surroundings and hinterlands presently known with any certainty. For instance what was the impact of the Droitwich salt industry on the surrounding woodland areas, in terms of its fuel supply over 2500 years? (Hurst forthcoming). A substantial number of processes were mechanised in the medieval period, such as fulling and corn milling which were operated by water-powered mills. It is quite striking that one of the commonest types of industrial site was the watermill (for instance there were about 100 mills in medieval Herefordshire), and yet a large number of these cannot now be located. The remains of these structures must be concentrated on river banks, and could now be encased in alluvium and, therefore, well preserved. Walking up stream-beds in order to look for remains in the banks of streams might be one way to rediscover some of these sites. Such a streambed survey could be combined with looking also for small deposits of peat, which have been overlooked by geological mappers, but which incorporate a unique record of past landscape in the local area despite their size (Pearson and Williams forthcoming). There are particular problems with investigating specific themes such as the iron industry in a heavily urban modern environment (eg Dudley), where the local economy has an effect on the extent of funding, and where development is piece-meal. This situation calls for a consistent application of carefully thought-out recording strategy, though the outcome may be less valuable for research purposes simply due to the difficult working circumstances. Much greater account should be taken of documentary evidence when reviewing the medieval town or countryside in terms of its industry. Archaeology may indicate only a fraction of the real extent of industrial activity, and is only useful for revealing specific types of activity. In some cases only documentary sources can provide the data that illuminates the past, and so an integrated historical and archaeological approach provides the best way forward to the study of medieval sites. There is a need for more synthesis of those sites already known about where trends could already be apparent in the data already collected. Some/most SMR’s do not pay sufficient attention to distinguishing the specific activities represented by the archaeological evidence. For instance, the term ‘metalworking slag’ is often used without indicating whether smelting or West Midlands Regional Research Framework for Archaeology, Seminar 5: Hurst 6 smithing is meant. There is a need for SMR’s to make more careful reference/inventory of material found during fieldwork, and subsequently identified by specialists.
