Continuity and Change
The transition from Iron Age to Roman periods in Cornwall is marked by a continuity of lifestyle and tradition. Rounds and enclosed settlements as well as unenclosed round house hamlets continued as the predominant forms of settlement. And there are few signs of Romanisation with only two known forts, at Restormel and Nanstallon near Bodmin, and a single villa at Magor near Camborne.
There were some changes: hillforts fell out of use, houses became oval instead of circular, and in West Penwith and the Isles of Scilly courtyard house settlements developed. These were a variant of round house settlements. They were unenclosed and contained a number of houses; each house consisting of a group of stone-built rooms arranged around a courtyard. They were in use from the second to the fourth centuries AD.
The fifth century was a time of political instability in Britain following Saxon incursions and the collapse of Roman rule. The following two hundred years or so were a time of great change marked in Cornwall by increasing contact with Wales, Ireland and Brittany, new trading contacts with south west France, and, most importantly, the introduction of Christianity.
During this time rounds and enclosed settlements fell out of use. The typical medieval hamlet, consisting of rectangular farmhouses arranged around a shared yard or townplace, developed between the fifth century and the Norman Conquest of 1066. Few settlements from this period of transition have been excavated and we know little about how this development took place. Analysis of the early medieval names of many Cornish farms implies that some of these hamlets were built on the site of former enclosed settlements; in other cases the enclosed settlement was abandoned and a new hamlet established close by.
Everyday life in Cornwall changed little under Roman rule; the archaeological record shows a remarkable degree of continuity from the later Iron Age. Enclosed farms or hamlets continued to be the predominant type of settlement in the countryside. Their number increased during this period, with an apparent spate of enclosure building taking place in the second century AD. It is possible that rectangular-shaped enclosures are a sign of Roman influence but this is not necessarily so and round enclosures were certainly built during the Romano-British period.
There were some changes. Hillforts fell out of use, probably before the end of the Iron Age and certainly by the Roman period. The design of houses developed; round houses were replaced by oval houses. The roof supports of oval houses rested directly on the walls of the house; the advantage being that the floor space was not cluttered by upright roof support posts as was the case with round houses.
During the Romano-British period in West Penwith and on the Isles of Scilly a new type of settlement unique to these two areas developed; the courtyard house. Courtyard house settlements were in use from the second to fourth centuries AD. Each settlement generally contains a group of courtyard houses, sometimes with round houses as well.
The houses are oval or irregular in shape and are enclosed by a massive stone-faced earth bank two to three metres thick. Within this enclosure are several rooms joined together and arranged around a paved courtyard. The usual arrangement consists of a round or oval room opposite the courtyard entrance with a long room to its right. Excavation has shown that the round or oval rooms served as domestic areas, and the long rooms housed animals or were used for storage. Archaeologists are uncertain whether the courtyards were roofed or not, but it seems most likely that they were not.
Most courtyard house settlements are unenclosed although some are found within rounds. Many developed directly from later Iron Age round house settlements; the round houses were incorporated into courtyard houses as rooms. Courtyard house settlements are farming hamlets like the rounds and unenclosed settlements with which they are contemporary.
From Romans to Normans
The end of the fourth century AD was a time of repeated upheaval in Britain. The Roman Empire came under ever increasing threat and shortly after AD 400 the armies were withdrawn for the defence of Italy. It is likely that around this time the government of the British province collapsed. From the 440s onwards large areas of Britain were lost to Saxon invaders. In the west, however, there remained a strong sub-Roman enclave whose power against the Saxons is symbolised by the legendary King Arthur.
Legend has it that Tintagel was the birth-place of King Arthur. Tintagel was originally thought to be a monastic site but is now generally accepted as the seat of power of the Dark Age kings who ruled Cornwall between the fifth and seventh centuries. There are numerous rectangular buildings from this period on the island and its special status is illustrated by the enormous quantities of imported pottery found there.
The fifth to seventh centuries, a period referred to by archaeologists as ‘post-Roman’, was a time of changes. The most significant of these was the adoption of Christianity, which was introduced from the Mediterranean and France and, particularly, from Wales. The early Christian foundations in Cornwall were, like those in Wales, not simply isolated churches, but actual settlements. They were called lanns and consisted of an enclosure which defined the consecrated area. Within the enclosure were probably houses, a cemetery and a chapel. Many parish churches are on the site of early Christian lanns. A good example is St Buryan where the lann enclosure is fossilised in the present-day churchyard. The lann enclosure re-used the line of the enclosing bank and ditch of an Iron Age or Romano-British enclosed settlement.
Very few post-Roman or early medieval settlements in Cornwall have been excavated and evidence for everyday rural life is sparse. There was continued occupation in some Cornish rounds; at Trethurgy oval houses were in use into the sixth century after which the round fell into disrepair.
At Tintagel the buildings dating from the post-Roman period are rectangular, but this was a site of special status and may not have been typical of everyday settlements. Buildings at Gwithian dating from the sixth to eighth centuries are small and sub circular. Each building contained a stone-lined hearth. These buildings are probably workshops rather than houses and there is evidence for iron smelting at this site.
What is certain is that by the tenth century the typical Cornish medieval settlement – a hamlet consisting of unenclosed groups of rectangular houses – had developed. Archaeologists do not fully understand the development from the oval houses of the Romano-British rounds to the rectangular houses of the medieval period, why enclosed settlements were abandoned, or what led to these changes.
The abandonment of rounds marked the end of a settlement tradition which had lasted for nearly a thousand years. At the same time pottery styles changed, and there was a change in trading contacts from the Mediterranean to France. Maritime contact with Wales, Ireland and Brittany intensified and a local British kingdom emerged, providing a degree of political stability.
Another factor which may have acted as a catalyst for change is the occurrence of a widespread natural disaster around AD 540. Although the nature of this event is uncertain it is linked to outbreaks of plague in the Mediterranean and resulted in restricted growth in trees for several years. We can guess that it also caused crop failures and, if it was accompanied by plague, may have led to a drop in population and the abandonment of settlements.
Against a changing political background, affected by contact with different people, it is perhaps not surprising that the post-Roman population gradually moved away from the old system which had been in place in one form or another since the later Iron Age. The adoption of Christianity meant that the ideologies and meanings of the past were being replaced. Crop failure and plague may have accelerated the degeneration of that old system. Enclosure, once a symbol of status and certainty, was now a symbol of the past.
The Pre-Norman Landscape
Very few post-Roman settlements have been excavated in Cornwall and we cannot say for sure what the typical form of settlement might have been. We do know, however, where many of them were. This knowledge comes from analysis of place-names and their meaning. Settlements regarded as medieval in origin are those that were first recorded in documents or on maps before 1540; in Cornwall there are roughly 7,500 of these.
The majority have Cornish rather than English names (for instance ‘Trebartha’ is a Cornish name, ‘Fernacre’ is English). The Cornish names which contain the elements tre meaning ‘farm’, ‘estate’, or ‘hamlet’, and bos, meaning ‘dwelling’, are known to be of early origin; farms with names like Tregiffian or Bosfranken may date from anywhere between the fifth and eleventh centuries but are most likely of post-Roman origin.
Of great interest is the fact that many rounds and enclosed settlements are situated close to farms with early medieval names. The inference is that enclosures such as this were abandoned and that the communities they once housed established new settlements nearby which have been in use ever since.
Another place-name element relevant to the changes in settlement in the post-Roman period is ker, meaning ‘fort’. Ker often appears as ‘caer’, ‘car’ or ‘cra’ in today’s place-names. Settlements with ker in their name may date from the fifth to seventh centuries. This name element is generally taken to mean the site of a round or enclosed settlement and this is borne out by field and aerial survey.
At Crasken near Helston the enclosing bank of an abadoned round is incorporated into the present-day field pattern. The name Crasken contains the early medieval element Ker. This suggests that occupation moved some time between the fifth and seventh centuries from the round to the site of today’s farm. It is very likely that today’s field hedges are built on the lines of the field pattern contemporary with the round. In the lower part of the field to the left of the round are the faint cropmark remains of a rectangular enclosure, which may also have been a settlement.
Not all farms with early medieval place-names have abandoned enclosures nearby. The most plausible explanation for this is that settlement here continued beyond the Roman period on the same site. In other words many medieval farms sit on top of prehistoric or Roman enclosed settlements and many of these settlements have been perpetuated up to today.
Comparison of the settlement pattern of enclosed settlements with the pattern of farms with early medieval names supports this idea, with the enclosures appearing to complement and fill gaps the early medieval pattern.
Of course we do not know to what extent occupation was continuous at each site. Some new settlements may have been established long after a nearby enclosure had been abandoned. Elsewhere enclosures may have been deliberately abandoned in favour of setting up a new settlement nearby.
