In the late 1950s, Guthrie concluded, in a paper entitled, Terraced fields at Boswednack, Zennor (Gutherie 1956), that the, small, narrow terraced fields may be medieval or later in date. Though he also writes that the field system at Boswednack does, superficially...resemble a late Iron Age or Romano-British agricultural pattern (1956, 166). These recent surveys undertaken by CAU does demonstrate that the underlying field systems at Boswednack are indeed prehistoric in origin. Field remains of an underlying prehistoric field system at Boswednack comprise of both ploughed out lynchets as well as substantially levetted stone faced walls. (so that in their very lowest courses lie in the structural elements of a prehistoric boundary). In some cases, the successional reuse of a prehistoric boundary is not only well defined by the substantial heights of revetted walls but also by the marked projection of a stony lynchet of the underlying boundary along which later field walls have been built. Particular clear-cut cases of this can be seen close to features 91201, 91202 and 91205. The best preserved traces of a late prehistoric field system are seen in the northern areas of the present field system where substantially - built terraced field still survive, echoing the pattern of terraced and rectilinear prehistoric fields that are a familiar pattern on other forms on this coastal plain. (see Nowakowski 1987A Fig.11). Further south and closer to the farmstead, traces of this earlier system are less well preserved and exist as mainly wide and ploughed out lynchets. This is probably a result of the creation of larger fields in these areas which have become regularly rolled and ploughed in recent times. There are no traces of this system on the western more overgrown areas of the property. It appears that this area was left unenclosed by the earliest farming occupants at Boswednack. Though the present dense nature of vegetation in this area made it particularly difficult for satisfactory detailed survey to be carried out. The relationships between prehistoric lynchets and the remains of hut circles at Boswednack has not been particularly easy to clarify. In some cases for example at feature 91190, a prehistoric field boundary appears to lie over or up against the hut platform, and this is also the case at feature 91198 where a lynchet (91199) does appear to overlie to the southern edges of the hut circle; thus implyling that it post-dates the hut feature. On the other hand, several hut circles at 91215 appear to be tacked on to a prehistoric boundary. Thus it is difficult to argue for the contemporaneity of both hut circle occupation and field system purely on survey evidence alone. Whilst they may well be contemporary such relationships can only be clarified by selective supervised archaeological excavation. On the other hand, the absence of any other type of settlement evidence contemporary with this field system preludes that both the hut circle phase is roughly, if not exactly, contemporary with the field system phase. In 1960 the Ordnance Survey remarked on the narrowness of some of the terraced fields at Boswednack (see OS Index SW43NW4) and concluded that this may denote a medieval strip-field type of cultivation. That these fields were used in the medieval periods at Boswednack is certain, though their origins are late prehistoric and similar types of terraced rectilinear field of Iron Age/Romano-British date have been recorded on other coastal Zennor farms. The extent of this system at Boswednack has been defined by this survey (see Nowakowski 1987A Fig. 11) and though not discussed in this report, the traces of a prehistoric field system south of Boswednack Farm (in fields covenanted by the Trust) do extent westwards, eastwards and southwards into the neighbouring farms of Gear and Pennance.
