Abstract: |
This report was commissioned by the National Trust, Saltram as part of a wider research project at Saltram. The two sites for geophysical survey were lawns to the east and south of the mansion, and an area of gently sloping parkland with a pond at its western extent. Fourteen magnetic anomaly groups and twenty resistance anomaly groups were identified as possibly representing archaeological deposits or features. The magnetic survey on the Mansion lawns was compromised by the presence of iron or steel services and iron lawn edgings. The resistance survey, however, suggests the presence of linear features on both lawns which may indicate archaeological deposits although some may relate to relatively recent service trenches. The majority of the magnetic and resistance anomaly groups recorded in the parkland area relate to informal tracks although one may indicate a former ditch or leat and another a ditch. Ploughing disturbance, possibly from ridge-and-furrow ploughing, was also recorded in the same area. The combination of tracks and ploughing may be responsible for slight, extant earthworks noted in previous work. A curvilinear feature is indicated in both the magnetic and resistance datasets to the east of the pond which may be natural but could relate to a former wall or drainage feature. Two relatively high resistance features were recorded within the Pond area. These indicate the presence of two stony or concrete deposits. |
