The site of the survey falls partly within the Scheduled Monument of Beeston Lodge. Beeston Lodge is the presumed location of the former Clipstone Peel. Measurements of vertical geomagnetic field gradient were determined using Bartington Grad601 dual fluxgate gradiometer. A parallel traverse scheme was employed, and data were logged in 20m grid units. The instrument sensitivity was nominally 0.03nT, the sample interval was 0.25m and the traverse interval was 1m. This initial phase of work has been designed as a starting point for long term research. The results have been a very interesting ‘first step’ in beginning to understand the site: The standing ruin consists of the remains of a rubble core of a stone wall orientated approximately north to south, there are also the possible remains (although buried under rubble and vegetation and hard to fully ascertain and record) of a wall which runs parallel, approximately 8 feet to the east of the standing wall. These two walls may be part of the same building. This standing ruin is surrounded by a large spread/mound of stone rubble presumed to be from the gradual collapse of this structure and other possible buildings on the site. Between the possible northern entrance and the standing ruin, the magnetometer may have revealed the remains of a series of buildings which may have formed a range running northeast to southwest from the entrance to the ruin. A series of buildings is depicted on the William Senior 1630 map of Clipstone lordship at the site. The area of rubble surrounding the upstanding ruin may also contain the remains of buildings or the robbed-out foundations of former buildings to the northwest of the standing ruin and to the south of the standing ruin. A possible ditch detected in the magnetometer survey running southwest from the ruin may have formed the extent of the site on this side. It is possible that the faint remains of former buildings lie within this enclosure to the north of the ditch. It is just possible that the anomalies detected here show something of the former extent of the site of Clipstone Peel, and the subsequent hunting lodge and the site later known as Beeston Lodge, and perhaps represent the first view of what survives beneath the soil on this important medieval site in Sherwood Forest.
