Magnetometer Results:

An irregularly shaped area of increased magnetic response is visible in the south-west of the survey area. Given that the response lies immediately next to a wall surrounding the Methodist Church, it is possible that it is related to this. Part of the response corresponds with a high resistance anomaly detected through the resistivity survey, and with complex responses visible in the GPR. It is therefore also possible that the response relates to possible brick/stone remains. However, given that the confines of the survey area are so small, further interpretation is difficult.

Two further areas of increased magnetic response are visible on the northern and eastern edges of the site. The northern response corresponds with anomalies detected in both the resistance and GPR surveys, while the eastern anomaly corresponds with an anomaly visible only in the GPR. Both features are of uncertain origin, and may relate to buried archaeological remains or be of more modern origin.

An area of negative response is visible across the north-east of the area. Similar to the responses above, this is also of uncertain origin. It may be possible that the response is a result of a former earthwork feature, though this interpretation is tentative at best.

Earth Resistance Results:

High resistance linear and discrete responses are visible across the area. A section of the linear response corresponds with a positive anomaly in the magnetic data, as well as a discrete response in the GPR. It is possible that this relates to a small section of wall, though it could also relate to a row of grave slabs given the proximity to the Methodist church (see MNT28638 for confirmed Roman wall).

The northern-most irregularly shaped area of high resistance corresponds with an area of complex and discrete responses in the GPR results, and as such may be representative of brick/stone remains. The larger discrete area of high resistance at the northern edge of the site may also be a result of brick or stone remains. The GPR data in this area shows strong discrete and complex responses, possibly indicative of fragmented structural remains.

An area of moderately high resistance is visible surrounding the areas of possible brick/stone remains. This area of moderately high resistance may be a result of additional scattered building debris or rubble, though it could also be of natural origin.

GPR Results:

Complex responses at depths between 0.33 and 1.17m are visible in the east of the area. These are possibly indicative of fragmented structural remains, i.e. brick or stone. Part of the amorphous, central response appears to correlate with an area of high resistance visible in the resistance data, further justifying its interpretation as being possible structural remains. The linear response, at depths varying from 0.33-1.17m may relate to a former small length of wall, though its exact origin cannot be determined with confidence.

A weak planar response is visible in the east of the area, at depths between 0.62 and 0.67m. This is possibly associated with a former buried surface, such as a floor or a grave slab.

A weak discrete response, at a depth of 1.15m, in the west of the area possibly relates to a buried obstruction, though it could also relate to a burial or grave.
