South West Archaeology Ltd. was commissioned to undertake an archaeological assessment, including a geophysical survey and Heritage Impact Assessment on land at Wheal Vor Road, Carleen, Cornwall. The site is located at the north-eastern edge of the settlement of Carleen, c.1.6km north of Breage and c.4.75km north-west of Helston at a height of c.95mAOD. The Tregonning and Gwinear mining area has a rich mining history and forms part of the Cornwall and West Devon World Heritage Site, assessment of the historic and cartographic sources indicating that the site forms part of the former Wheal Vor mine and is likely to have previously been common land open as grazing. Whilst Carleen has medieval origins, much of the village grew during the post-medieval period as a result of the significant mining in the area. Wheal Vor was one of the biggest and richest tin mines in the 19th century, and it is notable as being an innovative sett, having been the first mine in Cornwall to use steam power for de-watering the mine, with a Savery pump in the late 17th century and Newcommen pump added in the early 18th century. It was also the first to erect a Brunton calciner in 1835. The geophysical survey identified four groups of anomalies. The anomalies identified include: known (Group 1) and possible (Group 2) shafts or mine workings; disturbed ground as a result of mine workings (Group 3); and a modern drain (Group 4). Any development of the site is likely to encounter and destroy the buried archaeological resource, and whilst there is a high potential suggested by the surrounding prehistoric and post-medieval mining landscape, the results of the geophysical survey would suggest that the archaeological potential for the site is moderate, many of the identified anomalies likely reflecting post-medieval mining. Whilst further archaeological mitigation in the form of a conditioned watching brief or targeted evaluation trenching may be required to validate and clarify the results of the geophysical survey, previous mining survey trenching has already identified the scale and nature of the mining features present on the site. In terms of indirect impacts, most of the designated heritage assets in the wider area are located at such a distance as to minimize the impact of the proposed development, or else the contribution of setting to overall significance is less important than other factors. The landscape context of many of these buildings and monuments is such that they would...
