The images below present EMI (MSa) and magnetometry data from one survey location to the south of a Roman road. This survey location was bordered by a modern tarmac road, metal fencing and modern housing.
The EMI survey highlighted 3 areas of increased magnetic susceptibility (MSa) at the southern edge of the Roman road (top of EMI image). The magnetometer survey confirmed these as representing remains of small earthen dwellings/hut sites, each measuring c.5m x 8m in diameter. Further hut locations, pit remains and shallow negatives in the magnetometry indicate remains of settlement extending southwards beyond the immediate vicinity of the Roman road.
