Report summary,"The magnetometer survey suggests that there may be a particular concentration of magnetic material, probably fired brick, in the ditch section near the fort’s western corner. There is no sufficient evidence to offer a certain explanation of this concentration; possibilities include an otherwise unproven corner tower having collapsed, a theory which could be tested by excavation, if enough of the wall and/or tower foundations survive."
