Abstract: |
This report was commissioned by Timothy Dart Ltd. on behalf of clients. It has been prepared as part of a programme of work in support of a forthcoming planning application at the above site. The magnetic contrast across the area was sufficient to be able to differentiate between anomalies representing possible archaeological features and background magnetic responses. Nineteen magnetic anomaly groups were identified as relating to possible archaeological deposits or features. Of these, one group may represent a linear group of pits. A spatially relatively concentrated set of irregular magnetically positive anomalies could signify an in-situ but mainly ploughed-out archaeological deposit. A set of linear anomalies is likely to represent a former Cornish bank field boundary not mapped on any historical Ordnance Survey map. A sub-circular group of anomalies, highly disrupted by relatively recent ploughing, may denote an archaeologically significant sub-circular deposit such as a filled ring ditch or round-house. The place-name element 'bethow' of the local Early-Medieval/Medieval settlement Penbetha suggests the site of a barrow (HER 22892.10) which could have relevance here. In the southern part of the survey area a group of adjacent oval-shaped anomalies may represent a cluster of archaeological deposits such as pits or large postholes although a natural origin cannot be ruled out. The remaining anomalies mapped as potentially archaeologically significant are likely to relate to field boundaries or other enclosures of more than one phase of previous land management. |
